I have a friend that just installed performer heads 1.6 rr and a steeda cam on his sn95 302. the car starts, but the idle is rough, even for the cam he has. the cylinders also make a popping sound. the wierd thing is when you unplug the maf the idle steadies out, and the car becomes somewhat driveable but totally gutless. would anyone have any idea what the problem would be?
timing is good fuel pump is good fpr is good fuel filter brand new spark plugs are brand new
any help would be much appreciated
thanks mike,

if u unplug the MAF and it gets better then most likely it's bad. that's one way to check.

Mine did the same thing, mine has a blower though, but it ended up needing a tune

Just as a heads up 94-95 mustangs don't like largeer than stock cams and will give you some issues. If it ran ok before the hci swap you can probally rule out the maf. When you disconnect the maf the ecu goes into a pre determined fuel map (fail safe mode) since it can't read the maf to tell how much air flow is being drawn into the engine. You can try cleaning the maf and then retrying. It probally is the maf, But not all the times it is.
