idle issues my fellow ford drivers need help

Thegreensnail · Sep 13, 2011

What's up guys I just did a whole engine build and swap but she ain't staying on
So far this is all I did a 306 speed pro pistons,pro comp 210 heads f can 1.6 rockers edelbrock victor Jr intake and a Paxton gss self contained supercharger, I deleted ac smog and and the tried.the egr its still in there but barely mounted...so the problem is the car will start just fine and rev up just fine but it will shut off as soon as I let go of the peddle, and I have no tune or anything done the ecm, this is on a 95 gts...so any ideas and help is needed

I would start with testing the TPS signal voltage with the throttle closed. It needs to be between .65 - 1.25v with about 1v being optimal.

Yeah I tried the whole 5 step article thingy and nothing, replaced my harness checked fuel pressure and its all good, but I'm running out of ideas

Vacuum issue?

Reset base idle. I would get it going first then put the sc on.

he said he has no tune done the computer is trying to compensate for all the additives thats now on it. thats what i think and rz5.0, i agree with you to start where you said to

That's exactly what I've been doing trying to get it to run good as is then throw in the blower, you guys know where I could get a chip? Plus I also have a chp pd ecm I heard those are good on modified cars but hearing and people with experience is two different things. Would anyone recommend me trying to install it?

I dont think its compatible. You are talking about a fox ecu from a cop car right.

Yeah from a fox, and yeah I don't think they are idk what the hell I was thinking haha probably all the bangs in my head got to me haha, well I put her all together last night for the second time and hopefully she runs good, my brother said he had issues on his saleen when first installing the f cam too from not idling because I guess the ecm was going crazy not knowing what was going on
