So my 01 is starting to feel like an old car . and what i mean by that is when you blip the throttle maybe in 1st or 2nd gear or even when you get off the throttle sometimes, the car will kinda rock back and forth like the motor is moving, kinda like an old worn car.

my question is what is the most common problem for this? i know its something wearing out. my car has 127k miles on it now and it was find just until recently. Are the motor mounts getting severely worn? or can it be something else?

 

could be motor mounts? hard to diag a car over the computer. u need to put the car in the air and get a jack on it to see it the mounts are cracked and comming apart.

 

does it feel like its the back end moving? When you apply the gas does the car seem to drift one way or the other? it could be something as simple as the tire pressue, but its hard to diag over the computer.

 

if it's an engine stumble i'd say check your vac lines. after 120K of heat, some may be cracking and leaking. a small vac leak could certainly cause a bit of an on/off throttle stumble. the carb cleaner trick could help you find it.

also, what kind of gas have you been running? changed the fuel filter recently? how are the plugs?

interweb diagnosing is hard, but those are some preliminary thoughts.

 

yea just looking for some suggestions, too bad none of you are in my area to feel it.

ill check the vac lines, whats the carb cleaner trick? ive been running 91 octane, thas the highest we have here in colorado.

i have not changed the fuel filter...i probably should do that as well.

 

valves or vacume hose. Valves need adjustments, though it is not knocking, bc it "may" cause thottle to not push in enough air in the engine to throttle. mine is slighly throttling if i slighly press on gas, not in gear, then as it dies down, it throttles. Mechanic said it might be my valves too tight or loose.

 

ahhh ok, im just gonna have dealership check it out, they are doing a free valve adjustment for me tomorrow anyways. thanks for the info guys!
