I changed the Head on 5.4 triton 2v. The mechanic didn't set timing correct and the vehicle wouldn't crank. Then I set the timing per the manual and it cranked. Sounded really rough and would not stay running. I have changed the starter, starter block, battery, IAC. It will crank up but is idleing low and is hesitating with some backfire. I am afraid to take it out of the driveway for the fact that I may not get it back. Anything I can do to check and see why it is hesitating
have the same problem?
