hesitation ,surging

[shodazzl]

Whatsup Guys,I did A 60 k on my car,plugs ,wires ,shims,fuel filter.But the car was still hesitating above about 35mph.I replaced the tps,but no go.What other possibilities are there?The hesitation is not that bad,but you do feel it.Could it be from some type of tranny hangup thats making it surge?The rpm gauage looks steady but the engine doesn't have constant throttle all the time.MAYBE bad egr??Any suggestions 93 atx

Clean out the IAB and the EGR system. Most likely this IS the root of your troubles. wink

Also make sure that your engine computer ground strap is tight. This happened to me, but my car was backfiring, caughing, and the Tach was all over the place. I don't think that this will be it, but I thought that I would check.

Also did you make sure that your timing was correct? Once again one thing to check.

Chris,My car was running that way even before I replaced my timing belt,Pretty sure about my timing.my iab is not cleanable,and the egr-Both cost about the same to replace $100,Man after all service I still need more.
