really. rough idle on cold start

[getatmydsm]

My 92 Talon has a really rough idle when i start it up sometimes it dies if i don't let it idle long enough. Does. Anyone know what is going on. O yea. It has a new battery n I'm just about positive the alternater is good

i would check your spark plugs and ignition system. dont sound like an electrical issue at all but if your wondering once your car is idling steady (once warm im guessing) turn on ## dome light if its flickering then you alt is bad.

but like i dais more of a spark issue to me.

Yea. I changed out my plugs and wirestwo months ago so it can't be them

Vacuum leak, BISS adjustment, bad ISC...take your pick...

 

[getatmydsm]

Its not a vacuum clear but I'll check the other stuff and get back to you guys

How do you know its not a vacuum leak? Have you checked? I see your N/T but a boost leak test and a mechanics vacuum gauge would prove valuable here.

doesn't matter if you just bought them 2day or two months ago checking em is still part of the process. things go wrong and nothing is guarantied not to break.
check it out anyways as well as the boost leak. then once its been ruled out by test then you can move on to something else.
