Car loses power in 3rd gear

Do you have the sinking feeling that the horses under your hood have turned into ponies? Does your four-banger feel more like a three-and-a-half-banger these days? If so, you might have a power problem. Back when carburetors were king and fuel pumps were mechanical, power loss usually came down to vapor lock or a clogged fuel filter [source: Goms ].

Today's intricate fuel systems have largely conquered the former if not the latter. Even so, all that complexity brings with it a slew of potential failure points. The same goes for the car's air intake and exhaust systems, particularly since catalytic converters became standard equipment in the late s [source: Newman ].

In many ways, though, the old rules still apply. Like your own body, every car needs fuel to burn and air to breathe. Your vehicle doesn't like running in high altitudes with a potato crammed up its tailpipe any more than you would but, hey, to each his own. If only nailing down the causes of power loss were as simple as a tuber in the tailpipe, we wouldn't make such a hash out of diagnosing them.

But identifying a power problem can try the patience of a saint, and doubly so when the drop in oomph occurs intermittently, virtually guaranteeing that your mechanic won't be able to reproduce it.

It also has power in first and second gear. The problem happens when i am driving up a long incline, I will be in third or fourth gear flooring the gas but my rpm's wont go up and neither will my speed.

What might be causing this and what parts would I have to change to fix this problem? First of all This is not a problem with your vehicle its general physics and applies to all vehicles.

Horsepower determines how fast a vehicle can travel, torque at the wheels determines how quickly that speed can be reached. The greater the torque figure, the faster the acceleration. The easiest way to picture what torque is, is by loosening a wheel nut. Try to loosen the nut by pulling on the spanner at the same end as the nut very little torque and you'll struggle to loosen it. Pull on the spanner at the end of its shaft maximum torque and you'll loosen it quickly.

Sogears 1,2,3 have higher torque but less power allowing you to move from a stand still gears 4,5,6 have higer power which help in rolling acceleration once you hit a particular speed.

This is not a problem. This is perfectly normal. Unless your car has immense power, you will need low gears to climb steep inclines. The higher the gear, the lower the effective torque available for acceleration. This is part of the trade-off gears give you:. The question does not specify what speeds are being attained or what grade of incline is being climbed, so this is a generic answer. If the vehicle cannot accelerate anymore it is due to a lack of power.

Basically the resistances against the vehicle such as the weight of the vehicle against gravity on the incline, and aerodynamic drag have used all of the engines available power. Check the flowmeter. If it is faulty, it gives wrong message to the fuel intake and therefore not enough fuel enters the engine. Sign up to join this community. The best answers are voted up and rise to the top.

What car do you have? Active Oldest Votes.If your car loses power while driving, there are a number of potential causes. In order for a car to operate efficiently, it needs to regulate the correct flow of air, fuel and compression. Any compromise to this process could result in a significant loss of horsepower. While there is a wide range of problems that could impact your power, there are a number of common offenders that could be slowing down your journeys. The most likely issue is a clogged fuel filter.

The purpose of the fuel filter is to ensure that dirt and debris stay out of the fuel system, so over time, it may need cleaned or replaced. When the fuel filter is clogged, the fuel pump has to work much harder, resulting in a far less efficient drive. While the fuel filter is the most common problem with the fuel system and is the easiest to fix, a lack of power could also point to issues with the fuel line or the fuel pump.

If fuel injectors are either clogged or leaking, this can cause the car to struggle when trying to reach high revs. If there are fuel injector problems, these are likely to be accompanied by other problems, including issues with ignition, misfiring and even an increased smell of fuel around the car. If your engine warning light is on, this is a sign that there is a significant problem with your vehicle that requires the attention of a qualified mechanic.

Many modern cars have engine control units that will automatically put the car into limp mode when a problem is detected, restricting power in order to ensure that driving is safe and accidents are avoided.

If the light turns on with a false positive, this could also cause limp mode to be activated, even if there is no underlying issue.

In any case, you should still get the vehicle inspected as this false positive could point to a problem with the electronics. Turbochargers are increasingly fitted to engines as standard.

These work by increasing air pressure in the combustion chamber, allowing more fuel to be added to the mix so that more power is generated from the explosions in the cylinder. While turbos make engines more efficient, if anything goes wrong with them, the engine will lose power. Problems could be as simple as dirt or debris entering the turbo and causing issues with the mechanism.

Similarly, a simple hole or loose connection in the tubing will hugely impact on performance. Turbochargers also need oil to work effectively so ensure that oil and the oil filter are well maintained. The cooling system is designed to maintain the engine at a particular temperature. In very high external temperatures, an overloaded heating system would cause the cooling fan to start working harder, taking power away from the engine and reducing performance levels.

If the weather is cool and the engine is overheating, this points to a more serious problem. Always keep an eye on the engine temperature, as running with a hot engine is likely to cause serious permanent damage to a car. Power loss from an overheated cooling system could also be experienced if the car is at high altitudes, where the air is thin. If you feel your car is accelerating more slowly than usual, it could be a sign of a clogged catalytic converter. A clogged catalytic converter blocks gases, meaning that the engine cannot rev to its maximum capacity.

If this is the case, take the car to a mechanic where the problem can be diagnosed. For diesel carsthe diesel particulate filter DPF could also get blocked. The DPF is designed to remove diesel particulate matter or exhaust pollutant particles, however, like all filters, they have a finite capacity.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

My car loses alot of power going into third from second. It is like going from second to fourth in any other car. Does anybody else have this problem. And does anybody know why it would be doing this. Jul 17, 2. Jul 17, 3. Jul 28, 4. Sep 19, 5. I have done a boost leek test a couple of days ago and it held 20psi for about 1. So I don't think that is the problem.

I think it might be the cat. I know my profile says I have a 3" test pipe, and I do, but none of the exhaust parts are on the car yet. Sep 26, 6. So nobody here has any idea what this could be. Sep 26, 7. Sep 27, 8. Sep 28, 9. Some other thoughts: CatCon could be obstructed, exhaust manifold gasket leak, fuel filter clogged, intake leak i. Sep 28, One thing I know is there is no codes in the computer. Oct 16, One moment car was running perfectly, next, just loses power.

Hi There, What you are describing sounds like you may have a clogged or damaged catalytic converter. The catalytic converter converts toxic exhaust gases into less harmful pollutants that are suitable to be expelled into the atmosphere. When the catalytic converter is clogged, this causes these gases to be backed up into the exhaust system not allowing the engine to breathe properly. When this happens, the engine is forced to work much harder to expel these gases.

This often results in the engine bogging down, hesitating, shaking and causing very poor fuel economy. This should also cause a check engine light to come on as the O2 sensors should be reading the incorrect amounts of oxygen in the exhaust gases if this is your problem.

I would recommend having an expert from YourMechanic come to your location to diagnose and replace your catalytic converter.

Car loses alot of power in third gear.

When I'm driving, and the car changes from 1st to 2nd gear and with my foot on the accelerator, the engine sputters and the car loses power and then slowly catches up. It also does this when going from 2nd to 3rd. But its not there or at least noticeable when going from 3rd to 4th gear. No check engine light warning either. This problem occurred all of sudden and not gradually, i.

After problem occurred, drove the car home and parked it in the driveway and turned off car.
