EGT Question
--------------------------------------------------------------------------------
I have a 94 TA with a 383 Golen engine with an ATI Procharger D1SC, Pacesetter long tubes, Magnaflow cats, MSD 6btm ignition with NGK TR6 plugs. Opti is about 3ys old with about 6k miles on it. It is one of the Dynaspark models. I have some initial tuning done by pcmforless (Bryan). The motor only has about 200 miles on it and I am getting a miss that is increasing in severity. I pulled # 1 plug and it is carboned and black. I am going to pull all the plugs and check or replace them. The car under load feels like it is popping or missing. Occasionally it seems like it is back firing. I also noticed when I pulled the car into the garage to check for spark leaks near the wires while in the dark, my # 5 header tube is glowing slightly red at the bend.
My plan was to pull the plugs and check, replace if needed. Gap to 35 for the supercharger. Check the coil although it is a new MSD blaster and should be ok. I will also check the wires for damage and tightness at the optispark. After this if I still have the miss I was going to disconnect the msd box and connect only the factory ignition in case the msd is bad. I data logged the car and my long terms are at 128 but the short terms are around 138-150. The 1st tune had me rich and kept the long terms at 108-114. I had this tune in for about 40 miles prior to adjusting with the current tune.
As of yet I have not had the car tuned on the dyno but am planning to do so. I dont know if the plugs are carboned because of an ignition problem or if I have a fuel or tuning issue. I also dont know if the header being red is normal at idle but I dont think so.
Any ideas from you guys would be greatly appreciated.
Thanks in advance.
