PCM trouble too

[ptgtjoe]

The other day, I started to experience the dreaded 'hiccup'....but instead of at high RPM, I'm getting it at 2k-2.5k...has anyone else had this issue? Does the TSB cover this also?

I asked at my dealer two weeks ago, and they acted like they were going to order it, but I haven't heard anything....I'm gonna call them tomorrow!

I think this is another NEW problem to add to the list. The "hiccup" as it's being called now is experienced above 5200rpm at WOT. I'm not too sure what your problem is, it could be a number of things...

Yea, I only had the misfire above 5000RPM before my PCM was replaced.

I don't think it's a 'hiccup' I experience it also but only when I'm slowly accelerating (cruising) at around 35-40mph. I think it's just shifting (a little hard) into the final gear. I'll pay more attention the next few days...

Well, I called the dealer today, and they are going to look at it next Tues. I explained about the problem to my service manager, and also advised of the TSB, and he assures me that they'll be able to fix it, whatever it is. I'll keep you informed.

By the way...the hiccup is only getting worse....it was only mostly in second gear last week, but now it's happening in all gears!

Ok....well, got the GT back, and it turns out the problem was not the PCM....they told me that two spark plugs were 'glazed'....I've never heard of that before....but they replaced the plugs, and I tested it out on the way home....seems ok now...no more stalling, or stuttering.....the dealer claims that I do not need the PCM upgrade.
