I have 02 s2k 55k and im getting a hesitation around 6k 7k rpms. Any suggestions. Jus have I/e. Do for an oil change but no significant probs ever.

 

how is the oil level?

 

map whack, search it might help

 

Oil level is fine no prob there.

 

Check the MAP.

 

Do you have a CAI? Has it rained recently?

 

Any particular reason a flooded CAI would wait for 6k rpm to result in engine hesitation?

I'm seconding the map whack diagnosis

 

I'll 3rd the MAP sensor.

 

If that's what Billman say's, DO IT!!

 

after completing this (TSB 04-073 Intermittent Hesitation During Hard Acceleration ) you will not need to do the so called "map whack".

I still don't know why everyone still brings up the map whack. pulling and reinstalling the plug would be better then whacking the damb thing.
