For the past month Ive been dealing w/ a mysterious electrical issue where the car would break up when at 4,000 RPM's. It would not do it as bad when cold, it would pull to redline but once it warmed up it would hit a brick wall and fall flat on its face at 4,000 RPMS or slightly before. Tried a different coil, put new park plug wires on, check the Spark plugs, tested the TPS, Tried a new TFI, cleaned the brass connections on the cap, nothing would work. As a final effort I decided to try a new ECU.
Tonight pulled the car out of the garage it was running fine. I put the ECU in which I bought that came out of 95 Cobra. The car started up and ran for about 3-4 seconds and would just die. I tried my original computer and it did the same exact thing. It does it w/ my SCT chip in and out and with both ECU's. I just dont get it, it was running fine this whole time (just not above 4,000 RPM's) but now the car will not even stay running. Im really at a loss for what to do now.
