I didn't think i would have to be posting anything for a while on here except my opinions to help others but i guess it's my turn again lol..

Ok so i have my 2nd new engine in and have almost 2000 miles on it, and just yesterday with the A/C on it threw the SES light on, i took it to advance and had it read and it showed misfire #1 cylinder..shut the A/C off the light goes off after a few minutes..i verified it several times and it triggers the misfire Only when the a/c is on..anyone ever come across this before?

 

*Merged with your previous misfire thread*

 

i dont know why but, blazers and misfires seem to go hand in hand for some odd reason...

 

Has anyone ever figured a fix for this code. Done everthing mentioned in this thread and have same issue.
