Inconsistent idle
Hey guys, I dropped a GT40 crate motor in my car....and car sometimes stalls when coming to a stop....its starts fine...but has an issue holding idle....I did all the normal trouble shooting....does anyone know what the stock lph is? I thought 155 but not sure....dont know if this could be the issue.....??I pulled the motor out of my other car where it ran great but that car had a 190 pump in it? Any thoughts? Car at idle is at 32 psi fuel.....24# injectors....yeah I think that bout sums it up.....thanks all

Deng 88lph? Wonder if thats my issue...vac leaks were checked....all seems well...I searched a bit and found people who had similar issue and it turned out being the fuel pump? But I dont know worked great before just seems weird that all of a sudden it took a crap....unless the issue is that the pump is "stock"....thats a diff story...whacha think???

you could try cleaning the IAC and the MAf...and try running a koeo/koer test to check for any codes also the multi pack connectors behind the intake or/ clipped to it were a common problem of corrosion getting inside the pin connections and cause multiple issues like such...cleaning those and installing some contact cleaner/dialectic grease is worth a try!

RE: Inconsistent idle
the only way i could get mine to idle is to open up the buterfly a little then I had to reset the tpssensor now it idles.
the motor would stop when I stopped.I have a kirban adj. reg. and adjusting the fuel pressure had no effect on idle.
If you dont have that guage to read the sensor I paid 5 bucks for mine at harbor frieght.
