What you are describing is the inability of the engine to take a wider throttle setting. I would clean the MAF (Mass Air Flow) sensor first to see if that clears up the issue. The MAF senses the amount of air coming into the air intake, if it is dirty or damaged it will not send the correct signal to the ECM and in turn the proper fuel mixture will not be delivered to the engine cylinders. Cleaning a MAF is fairly simple, but requires some caution. The MAF is rather fragile and should only be cleaned with MAF Sensor Cleaner. Simply follow the instructions on the product. The MAF is normally located on the air intake system directly behind the air filter box.

This sounds like an ignition problem, when spark plugs get old they don't work as well under load, first step, replace them, while you are there, check the wires, or coil packs for shorts, sometimes you can see where they have been shorting out, 2001, I think staill has a distributor, caps and rotors go bad too, inspect carefully, or just replace tham, they can get carbon traces in them causing missing. Hope this helps, and you just need new plugs!

Car cuts out when you push on accelerator like to take off or something


Make sure you don't have a clean air filter. It might be short on air intake.

Air conditioner stops when i accelerate rapidly


The air cond compressor is supposed to stop, but only if the gas pedal is pushed to the floor.
If it is cutting off and the pedal is not all the way down, you could have a problem with the throttle position sensor.
Cutting off during hard acceleration gives you a few more horsepower.

(1)Car overheating (2)Car starting and cutting out


1- There are 2 fan systems in your car. One is a fan clutch. the other is electric fan. The electric fan is still working, but the fan clutch is not. Replace the fan clutch will take care of this problem. 2- When you put flat down on accelerator the car starts since at this position the throttle body open all the way making a correct air: fuel ratio of 14.6 :1. When you release the accelerator,the throttle body has to go back to it preset position and at this position it didn't make a correct air: fuel ratio of 14.6 causing the engine die instantly. This means your throttle body needs cleaned. There is a vacuum thermal valve at the top engine block to answer your question. It can be easily identified by looking at 2 vacuum hoses from this valve running down to the throttle body.

1992 toyota camry v6 le boggs down on acceleration


It sounds like you may have a vacuum leak. Your car should normally idle at about 700-750 RPM. You said that yours was at about 1000-1500, that is waaay to high. If you have a leak somewhere in the system the car will draw in extra air and it will want to idle much higher and will also be very erratic and hard to drive.

Hesitation , skipping,engine cuts out when accelerating


Im having the same issue I believe. I have a 94\' Chevy 1500 and when i accelerate it will jerk like the gas has cut out but it wont stall. It just jerks and slows me down. It only seems to do it when going up a hill. I feel like it could be the fuel pump or possibly some intake gaskets?
