adjust your idle speed

I know you said that it has a rough "idle", but just to make sure, does it smooth out as you give it a little gas?

Is is a rough "idle" or does the idle just do a fluctuating thing ??
Did you over-rev your engine at all ?? possibly miss a shift and it shot past redline ??

idle was adjusted and when i come to a stop light it starts to fluctuate and go up and down, and kind of wants to take off.

i drove it tonite and it was fine, then on the way home it starts sputtering again, i startin to think i should trade it in for somethin with less problems

i kinda had the similar prob with my 95 max, wen idle it sputters, turns out the injectors were real dirty, could be that

jaykid806

what stuff should i run threw my car for injectors, i ran slick50 hi-mileage fuel system stuff threw is that good enough?

jaykid806

Check your Throttle Position Sensoor...I garentee its that

Could the TPS malfunctioning be causing my throttle to be jerky. When I am driving and I let off the throttle(slowly or abruptly), the car jerks badly. The same problem happens when I slowly accelerate while coasting. When applying throttle, acceleration isn't smooth. The engine seems to stumble and then all of a sudden the car jerks and then accelerates smoothly.

same with me, the tps is clean it took it apart and was very clean, idk and its drivin me crazy

yeah you cant clean the TPS, you can adjust it, i think jaykid is under the impression that the throttle body is the TPS, but its not, check your haynes manual on how to adjusting and checking with a multimeter

jaykid806

no i didn't clean the tps i was clean when i took it apart, and i know the difference between the tps and the throttle body! should i have the tps replaced if so how much does it cost? the part?

TPS=Throttle Position Sensor....TPS's are alittle over $100
