    I have a 93 firebird with a pcm of the matching year that I am currently rebuilding from the ground up.

    I have a 95 Firebird Formula that ticks cold or warm, 5 times fast, every 10 seconds or so at idle. As the rpm goes up, the ticking happens more frequently.

    I have a 1994 LT1 swaped into a 83 El Camino. The car will run off of starter fluid but will not run on its own. I have about 50 lb of fuel pressure and the fuel pump relay is working. And I paid someone to disabled VATS in the PCM. Someone cut out the ALDL of the harness so I cannot check codes...
