Looking for some ideas everyone. I have a 94 sc that while driving the other day just started to die if I was not pushing the gas. Ran the codes on the obd 1 and it came up with 126 and 181. Basically saying barometric pressure not in range. Tried replacing the IAC and spark plugs( cause they needed it and figures who knows). But still not doing anything. I did order a biometric pressure sensor but for the life of me could not figure out where the hell that sucker went. Think it was for s different engine even thought it said in autozone system it fit my car. Anyway anyone had this happen and have any ideas!?
