missing when cold

[texastud1983]

Hey guy, my 87 2.9L sounds like it is missing once I first start it up. I can rev it up and it still sounds to same, after about a minute or so it starts running right. Any thoughts on what it might be?

Have you pulled any codes from the computer?
If you haven't or don't know how take you rig to auto zone or some place like that and they usually will come outside and read your codes for you no charge.
When ya get the codes write back and tell us what you have and we can proceed from there.

I am going to go out on limb and say coolent temp sensor...but yes you need to pull codes.

mine does the same exact thing... it runs like dog crap until it gets warm. i mean it misses if i'm puttin along but just fine when hammered and accelerating but just chugs when cruising along at lower rpms..
