Hey all,

my very-reliable '95 Fairmont just developed a bad misfire which is getting worse quickly (in just a couple of days).

Symptoms:
- only misfires when COLD
- misfire is only when pulling away from idle
- feels like it's dropped a cylinder (or two), it's a very regular "chugging" kind of misfire (not a stop/start, stuttering irregular kind)
- misfire DISAPPEARS when engine is warm
- no misfire at road revs or when up-to-speed
- misfore is getting noticeably worse every morning (since it started on the weekend).

Any ideas as a first go-to item to investigate, I'd appreciate any advice.
I've read a number of threads on this subject - sounds like inlet manifold gaskets are an issue - do these symptoms sound like that?

Cheers

Leads cause problems with ignition when they are cold thats when they are most likely to muck up so id check them first

then spark plugs, coil pack
