Hi everyone I have a 89 Gt that is stalling out at stop signs and lights intermittantly I will do my best to explain and list all the new mods. If I drive it normally to a stop sign it will retain the idle. If I say drive it hard to a stop sign at 2nd gear with the rpms up and put it in neutral it will slow down to 500 rpms and then try to catch itself but stalls out. If I reve it up before I pull it into my garage it does the same thing it seems to happen when the motor is under a load right before neutral.
The enigine is a new build with a trickflow top end H/C/I. It has approx 100 miles on it.
Everything is new just about, new vacum hoses, new tps sensor set at .98, new egr solonoid, new pro-m mass air calibrated for 24lb injectors, new 75mm TB, new iac, new coil. New plugs, wires, clutch cable, clutch, headers, exhaust, alternator.
I stil get a code 33 but I cleaned the egr valve and let it soak in carb cleaner for about 6 hours and that now looks like new.
Pulled the codes only got 44,94, 33
It was acting up bad until I replaced the CnL mass air to a pro-m.
I am stuck, I had some excellent help with it so far getting it to this point but we are at a loss I'm reaching out on all the sites for some extra help.
If anyone had this issue please let me know.
