Need help getting car to stay running?
I installed an 8 PSI 3-Core Intercooler Procharger in my 01 GT 5-speed. The install went pretty straight forward. I removed the Predator tune from the PCM and put in the supplied Diablosport Chip. I also installed a 90MM Lightning MAF and 42lb injectors, all new except for the MAF. The car started fine with no problem, let it idle for about 5-10 mins to check for noises, leaks, ect. found none so I blipped the throttle up to 4000 rpm made about 5-6 psi of boost then when the rpm's came back down the car stalled and would not restart.
I have done the following steps so far:
1. Disconnected battery to reset computer.
2. Removed Diablosport Chip to make sure terminal connections were clean.
3. Removed spark plugs, cleaned (heavily fuel fouled), and regapped to .052. The car now started but ran very rich(raw fuel coming out exhaust tips.) The car was rich it would not even rev past 3000rpm. Had to remove exhaust system to pour unburnt fuel from prochamber and mufflers.
4. Removed Diablosport Chip and tried to run on stock computer. Result were the same as step 3 above.
If left to sit for awhile the car will run for a few minutes before the it stalls from running to rich.
It appears as the the injectors are just dumping fuel into the engine with out regards to rpm.
The car initially started fine and idled but after I gave it some gas is when the problems started.
I plan on having the car dyno-tuned but I am trying to avoid paying a shop just to get it running then tune it.
Is it possible the plug gap is wrong?
Any suggestions would be appreciated?
