Just wondering b/c im thinkin of changing it to see if it helps my hesitation any

 

when under heavy load likegoing uphill it will hesitate and cut out on ya

 

what about at idle and off the start...woud a map sensor cause hes??

 

This question gets asked frequently. Anyone try the search button?

 

Well, if you can scan for codes, a bad MAP sensor would set codes 33 or 34. I doubt that it is bad as these sensors rarely fail.
Cleaning the throttle body and IAC would probably help a lot with the hesitation, unless you need new plugs.

 

same problem
