    I got in the GTP this morning and it is misfiring like crazy. I stopped at autozone on my way to work to have them scan it but it just came up as multiple misfires. I am going to change the plugs and wires and also have some gaskets (intense mls head,lim,valve cover gaskets) to change when I get some time but I am extremly busy and probably wont have time to do all that for a few weeks. Does anybody have any ideas as to why it is doing this. We didnt get rain here last nite and I was driving it fine yesterday but this am it sounds and drives terrible.The car just hit 90k last week and the engine temps are fine. I do smell burnt antifreeze but thats nothing new since it needs a L.I.M. gasket.

    How good are you about keeping up on the maintenance? Like, when was the last time you changed plugs, wires, fuel filter, air filter, oil, tranny fluid, etc.

    I would start with getting all maintenance up to date.

    I just got the car a month ago but rarely drive it. I have maby 300 miles on it since then but do not have any service records from the previous owner. Is it normal for it to just come up like that? It went from running beautiful to barely running. I though it would have gradually started running bad. I was driving it last nite and everything was fine then this am I started it and was like !! I figure I will start with plugs,wires,and coils then check all the vacum lines and try to track it down from there.

    I was able to look at it better when I got home from work, it turns out the middle coil pack was dead. I popped 3 new ones on and she runs great again. Thanks for the advice.
