This is my first post on this forum, but I've been reading for a couple years and learned a lot about the 3800 and how to fix problems with them (series 1 and 2 anyway). The problem I'm having is baffling me and a few others as well, so I figured I'd post here and ask for some help.
I have a '99 Grand Prix GT that runs great when it wants to run. Sometimes it will choke up and die while I'm driving, sometimes it won't even start at all. I've replaced the battery, fuel filter, spark plugs and wires, crankshaft position sensor, and the ecu. I've tested the alternator, the coil packs, and fuel pressure and all check out fine.
I'm wondering if it could possibly be the ICU or the security system (damn passlock system). At this point I'm just tired of dumping time and money into it just to end up back at square one. Any help would be greatly appreciated.
Side note: If I posted this in the wrong section I apologize. Sort of new to using this forum.
