My car is hesitating...again

[JUNIOR]

sometimes it does it and sometimes it doesnt....like if im at a light, and i press the gas a little to take off it acts like it want to bog down and shut off for a lil bit, then goes....and then if im on the freeway in high rpms and floor it, it starts pinging and popping, but if i ease on it, it will rev up fine....someone told me to replace the throttle position sensor, but i wanted a second opinion before i spend unecessary money, pleas help..so far i've replaced

coil, rotor plug, wires...what else could it be!!???

[mozzandherb]

could be a problem with your fuel system. Man it's hard to say because there's a lot of things that could cause that to happen.

[Losiracer2]

also check to see if you have any oil fouling in the spark plug chambers or on the plugs themselves, because if you dont have a good enough spark, it can cause pinging and misfiring so just inspect that area.

pinging and popping isnt good lol. You done any work to the car recently? Basic tune up yet? I would start with your basic tune up. But if you kept up with basic tune up and stuff wouldnt worry about it. If you feel hesitation constantly in the same rpm range it could be your tps.

[JUNIOR]

Yea it bogs out when i try to take off and at wide open throttle only....i think my TPS might have some dead spots and not recognizing wide open throttle...

[JUNIOR]

someone said my timing belt might have skipped a tooth and the tensioner my be loose....could that be it? thats what the mechanics said, ive bought everything having to do with ignition...fuel pump still good....im soo frustrated with this dam car!!!

[NAiL05]

Well when was the last time you did a timing job on your car. A tps will be consistent even if its partial throttle. You sure your timing and everything is set right. If you advance it too much it can cause pinging. BUt yea.

[JUNIOR]

yea, i have never done a timing job on it....the mechanic sade it probably skipped a tooth cause the tensioner gets weak sometime and its probably due for a timing job anyway....could that be the reason?

[NAiL05]

Could be you never know. Whats your mileage on your car.

[JUNIOR]

about 160,000

[npor]

just swap to an H22

[JUNIOR]

I know huh? im tiring of tinkering with a motor that has no potential....BTW how much would it be for a full h22 swap, labor and all?...just a ball park figure?

[NAiL05]

Well 160000 is bout time for another timing belt if you change every 80k miles. Which is about right. I recommend 70k-85k depending on driving.

[F22HB]

Or, you could upgrade to an A6 intake manifold. Its even got the tps.
