1999 GTP help...stalling, lurching, won't start intermittently

Hi guys. New here.

The wife has a 99 GTP and it will sometimes just stall. Sometimes it won't start....it will turn over just fine but not fire up. She also mentioned a "lurching forward". I am assuming it is all the same problem....hoping rather.

I am also hoping this is a "common" issue and has been discussed and diagnosed here before. Any help is greatly appreciated as I would like to buy parts and fix it tonight if possible.
 


First things first...any check engine lights? If so...try and get the codes off of it...that'll help A TON.

Secondly, Unplug the MAF on the top of the throttle body, then start it. Sometimes they'll turn over and even start for a second or two if the MAF is toast...then it'll "buck", or "lurch"...then die.

Thirdly, have the ICM checked if all it is doing is cranking over (Ignition Control Module)...it is what the coil packs bolt to. Any auto parts store should test it for free...the last couple things I suggest is if you can get it running long enough check for a massive vacuum leak around all the rubber "T" fittings around the fuel rail/supercharger/lower intake manifold.

Hope that helps.

It runs fine for the most part. This is intermittent. Here is what I did like 30 minutes ago.

So, I swapped out the MAF (was a remanned one if that matters). Everything was working fine. Took it for a test drive and from a slow speed, I floored it and it died. Made some strange clicking noise as it tried to keep idle. Started it, died. Started it, died. Started it and gave it gas to keep it alive and it was choking...perhaps starving of fuel?...don;t know. Died. Started it up and it ran perfectly.

Does the computer have to re-learn when a bad part has been replaced?
