Won't Idle
I have a 92 LX street/strip mustang that I've been building. I assembled a 347 for it and after finally being able to start it up I found that it won't idle and is running very rich. It will run as long as it does not fall below 2000 RPM.
The motor has a Pro-M 80mm mass air meter calibrated for the 42# Bosch injectors I'm using. 70mm throttle body, Holley Systemax intakes, PCV is not used (blocked at intake), EGR is still hooked up but not being used, using air temp sensor and water temp sensor in lower intake, using Bosch O2 sensors, throttle position sensor at .985 Volts, using stock computer.
I plan on installing a supercharger eventually so I went with larger injectors than I currently need. All sensors are new.
I've been talking with Pro-M and have even sent the meter back to adjust the calibration but we haven't been able to solve the problem yet.
Please respond with any questions or recommendations.
Thank you,
J.T. Munk
