Sounds like the engine control module is in the limp in mode. This can be caused by a bad sensor or the module itself. Do a diagnostic test with a code reader to determine the exact cause.

Sluggish Acceleration


A high mileage vehicle usually suffers from any number of maintenance related deficiencies. I would address the Fuel filter maintenance first. It's the cheapest and easiest of the solutions. Lack of fuel pressure under higher demand due to acceleration will result in a sluggish engine. The engine would idle fine and even run fine at high speed but would be sluggish under acceleration. Other more complecated solutions would be worn Ignition coils, Worn spark plugs, Timing belt stretched or jumped timing and the most expensive would be loss of compression in the cyllinders.

Tip

Loss in engine power, sluggish responses, low top speed, etc.


If your car has
  1. Poor fuel responses
  2. Lost its "power"
  3. Low RPM
  4. Lower top speed
  5. Burns a lot of fuel
Then it could be because of carbon build-ups in your engine's combustion chamber. This is left behind with unburned fuel. It causes poor acceleration, a loss in power, lower top speed, and burns more fuel than it really has too. Not to mention causes smoke belching.

The best way to get rid of that would be to have a carbon ridding solution injected into the combustion chamber. The solution will liquify the carbon and other build-ups, which would then restore the "power" of your car. You'll get better acceleration, higher rpm and top speed, save fuel, etc. have a mechanic do it for you. It's alot cheaper and faster than having the engine overhauled (overhaul could trigger "loose compression").

Complete loss of power on a hot day in heavy trafic, after about one hour power is back


Did the engine overheat and go into limp home mode? That would be my guess.

My engine 6G74 has lost pick and no acceleration, please advise on the possible causes


Um.... I know this is way late, but with the 6G74's either clogged injectors or worn out O2 sensor (located just before the catalytic converter) are the most common causes of sluggish acceleration/ power loss.

Get the injectors inspected & ultrasonically cleaned as this will make them perform like new. You can buy an O2 sensor for these either at your local auto shop or on line. Best to get a professional to do both of these if you are not too savvy with car servicing.

Momentarily Sluggish Acceleration


Are you loosing power to the ecu when the car is shut down? most cars with an ECU that controls timing, fuel, or boost can be forced to relearn the car if the ECU looses power (called a "limp" mode). I'd look into this. Also are you getting any check engine lights? considering the description of the problem, this would help to diagnose. Try getting the car started and running normally, then turn the car off but do not kill the power to the car, just stop the motor from running...Fire the engine back up and try to give the car a good stomp on the gas and see if you get the same sluggish problems...my 2 cents... Good luck future auto DIY's

1991 Toyota Corolla loud and sluggish


You need to do a compression test on the engine cylinders. It appears one of the cylinders is not firing and dragging the rest of the engine down in power. The compression test will show if one of the cylinders has a problem.

HOW TO CHANGE THE FUEL FILTER AND WHAT KIND OF PROBLEMS WOULD THE FUEL FILTER BE CAUSING?


The fuel filter is tucked away inside the frame, located on the drivers side, right about the middle of the door. If you crawl under the truck, looking up, you will see the fliter hidden neatly behind the beam of the frame. Its very easy to take off. Buy a new filter before you take the old one off, and you will then know what to look for. Hope this helps.
