well its got new plugs, got good compression, its still an awesome sled but this is like the first problem i have had with it
yea....no, i dont think i'd do a back flip on my zrt lol
If its the first problem you've had with it, I wouldn't be so quick to want to sell it and jump to a poo or a doo ....how long's it been since they made the ZRT?? First problem in 8-10 yrs, I'd say that's pretty damn good for any sled.
good that its got new plugs, but does it have spark?
if its got spark then I would start to go to the carbs. Cold start issue likely choke related to me. I don't think the outside temp has anything to do with it if it doesn't start at +3 or +25. What about the fuel pump, did your vacuum line come off?
Need more info.
