Hello all,
A little info first, new to SC's but not injected fords. I am putting a SC motor in a competition rock craleing buggy for a guy here on the board. Motor was delivered and we got it wired up and running. I am having several problems that leave me bit puzzled.
1. It runs wide open throttle great! or even part throttle. It surges at idle and wants to "hunt for the right idle"?? This motor has no egr and I have insured no vacuum leaks. fixed the ones I found.
I replaced the Idle Air Control valve since this is usually what fixes the problem on most fuely fords. If I allow the throttle to close slowly it will set and idle, but blip the throttle and it stalls when throttle closes adn then stumbles.
2. It drags when starting sometimes like timing is advanced to much on a normal 5.0. Will then start with a backfire and run fine besides the idle problem.
Do I need a new cam position sensor?? I also put a new MAF on it and it made no difference, new O2 sensors as well.
How do I know the cam position sensor is set right? It runs great when your are giving it gas.
Thanks for any advice...
