Acceleration Hesitant

" No CEL " - lost me?

Starts like normal regardless of engine temp.

Sorry... check engine light

I'd start with fuel filter & see if any improvement...it's the cheapest & easiest possibility.

Ok thanks for the input. Ill get on that tomorrow.

No CEL either..

There is a writeup around here somewhere on the "nuts & bolts" of fuel filter replacement.
IIRC, Spazz was the author.

Other possibilities (from recent personal experiences) are the TPS (throttle position sensor/switch) and/or the MAF (mass airflow sensor).

Has anyone done anything under the hood recently? If so, the connectors to the MAF or TPS may be loose, which will cause those symptoms.

Do you have a K&N-style (oiled) air filter? If yes, then it is very possible the oil has messed up the detector wires in the MAF, which can also cause the hesitation problem. CRC makes an MAF cleaner spray that will clear the oil residue off the wires, but don't use any other type of electrical contact cleaner. (Ldub, did you use the CRC spray on yours?) I had to replace mine twice with AutoZone rebuilds before I could get the engine running right (but that's another thread).

Good luck!

Yep, that's the "good stuff"...I don't leave home without it.
