maybe iac didnt seal right. valves would be individual misfire. only other thing i can think of is if the fpr lines didnt seal right maybe the fuel pressure is wrong. could be the fpr just picked now to go bad.

running there is a slight almost hiccup sound . sometimes its worse if i turn the A/C ON. if i drive it there is a slight miss sound but power is there , i can feel a miss in the acceleration . when checking out yesterday it would do it more then eased up? with the suck back at the tail pipe im leaning with a valve sticking? but what is confusing is the compression check? so im going to get some marvel mystey oil and add to the crank and as tank to see if it does anything.
