LT1 Stalling problem
Hey All, I have a LT1 with LT4 heads and gm hot cam kit with 6 speed in 1957 Belair, harness is Fuel Injection Connection and all input/output sensors have been replaced, Engine rebuilt and first time run. so now here is my problem, engine runs and idles fine although on the rich side while cold, once at operating temp (176DEG) Engine begins to run super rough and stalls out but will start back up and run for a few seconds then stalls. if left to drop to 160 degrees will start and idle/run until 176 degrees.
Here are some specs cold and then hot = fuel pressure 38 psi- 43 psi with vacuum removed, left H02s bank 2 - 0.85 to 0.89 v, right H02s bank 2 - 0.84 to0.88 v then hot left H02s - 0.84 to 0.89v and right H02s - 0.0v. I ohm'ed the injectors
cold then hot and they were #1-16.7-17.1 #3-16.7-17.1 #5-16.7-17.2 #7-16.7-17.2 #2-16.7-17.3 #4-16.7-17.2 #6-16.6-17.3 #8-16.8-17.4. I swopped 02 sensors left to right and it made no difference.
Any help would be appreciated, Thank You.
