I HAVE A 1991 3000GT VR4 MIT WHAT IT IS DOING IS WHEN I TRY TO PRESS ON THE GAS IT HESITATE?


Fuel-injected cars often experience clogs in the oil filter. This is especially a problem for cars that are filled up with low-quality gas and cars that have recently run out of gas. Try adding a fuel injector cleaner and filling up with premium gas for a couple weeks. In addition, check to see if the fuel injectors are functioning properly, and make sure the fuel pressure is within normal range.
For cars with carburetors, check the fuel pump. This is an essential part for fuel delivery, so it is the first thing to check when a car is hesitating during acceleration. It's also possible that the car is hesitating when accelerating because the carburetor is failing.
If the problem persists, have the spark plugs tested to see if there is a malfunction. Also inspect the wiring for frayed edges. Other things to check include the air filter, fuel filter, timing and gas leaks.

I've got a 1996 jeep grand Cherokee with the 5.2 v8 fuel injected Holley throttle body. My problem is while driving at soft or low acceleration it accelerates fine, but if you hit the throttle hard it


I would check the voltage on the throttle portion sensor with the engine off from idle to wide open throttle.If there are any dead spots, replace the sensor. If the tps checks out, you should check fuel pressure. If you have good fuel pressure, you may want to make sure there isn't a lot of slack in your timing chain. I don't believe you mentioned the mileage of your vehicle. Best of luck.

2001 dodge ram1500 /accelerates slow even w/peddle to the floor


How many miles on that rig? The 4.7 motor is a great motor.

Sounds like a fuel starvation issue. Might also be a trans issue. Does the trans seem to be shifting properly?? Could it be starting in 2nd gear which is the "limp mode" for Chrysler trannies?

Hesitates on acceleration


Does the car always hesitate during acceleration? If it ALWAYS struggles when it starts or ALWAYS hesitates on acceleration then I would say the issue is fuel delivery. If the problems are more intermittent and come-and-go then it could be an electrical issue.

I would start by changing the fuel filter. Changing plugs, wires, cap, and rotor are all good things to do as your budget will allow. I doubt you will have to change your injectors.

If you end up replacing any rubber fuel line, be sure to use the high-pressure stuff made for use on fuel injected cars.

I hope this helps! -Nick

Hesitation when accelerating, mostly between 20-30mph,


the funny thing is , we have had this problem also , the check engine lite came on , said downstream 02 sensor bad. replaced it. still had hesitation. change plugs and wires. still had hesitation, replaced fuel pump/fuel filter/fuel screen assembly, and the S.O.B. still has this problem. im running out of ideas except that i have run into other posts that say the crank position sensor , or the computer itself could be the culprit... all my switches and and other components seem to be working fine, though it makes me wonder also if tha cam sensor could also be going bad....
