Background info...this is in my LSC. 90 mustang 5.0, 89 mustang A9L computer, 93 mustang mass air, 95 mustang T5, 97 mustang rear end, it just looks and rides like a lincoln I did all the work and swapping.....anyway:
I'm driving along, coming to a stop sign and all of a sudden, the engine starts screaming shortly after I put the clutch in. I shut off the key, restart and it idles normally. 2 stop signs later, same thing happens, like the throttle is stuck at wide open. I get the car on the highway and it starts taking off in 5th now, randomly surging up to 90 then slowing down normally and surging for a few seconds at a time again. I get it off the highway and to a mall, replace the TPS, still does it, disconnect the IAC, still does it, disconnect the MAF, still does it. Now I'm freakin out, so I go pull the EEC out of my notch and swapped that into the lincoln and it's never run better, drove it 40 miles home without a glitch.....what the hell happened !? It went so high so fast, the stock tach got stuck in the dashboard! Thankfully I had my MSD set at about 6 grand and no severe engine damage occurred, but the EEC and tach signal were much higher than that somehow... anyone know what went wrong and how I can prevent this from happening again?
