2.5L convertiblw, 2000, 95,000
 

I have finally registered and hope to get some feedback on a frustrating issue. EVERYONE, everywhere has this problem with this vehicle, but I have yet to find, after days, weeks of research, THE ANSWER. Is today the day? My mechanic has been working on this for 4 days (finally found one that was willing to spend days on this issue, and now he's stumped too.) Accelerates like a champ. after 10 minutes, she hesitates. Computer shows it's missing on all 6cyl at some point, but no reason why. Yes, new timing belt, yes, double-checked for proper teeth alignment after install (again) Yes, 2 new distributors, 1st one was supposedly OEM, 2nd one from junkyard. New Plugs, Head gaskets, wires. I have driven it doing this for 18 months, never failed to get me from point A or B, just annoying hesitation keeps her off the interstate & going over 50 mph, it becomes nuts...Thanks for your time!:)

Finally picked up car today from my mechanic (2000 2.5L Sebring Convert). Yup, exhausted ALL avenues and the result was "90% sure it's in the computer". I opted at this time not to go the computer route as I am now out $1,000 trying to diagnose the hesitation at 220rpms/Misfire codes on all cylinders. It still has THE POWER back and drives like a dream, just can't drive over 50mph for any length of time, just 49 and under comfortably. Should I go for the computer and a "flash" ? Approx cost is $400.
($300 for comp/$100 for flash). Going to wait and save more $$ up and keep searching for the ANSWER: will_it_run? Thanks everybody for any suggestions!
