Cadillac Seville / Cadillac Eldorado Forum
Hi all, working on my 94 eldo base.
94 Northstar 4.6, it's idling rough, and has a random misfire, I have:
Replaced the fuel pump
Replaced the FPR
Cleaned the TB
Checked my wires
Confirmed all coils are working
Replaced PCV valve
Done a vacuum leak check with an unlit torch (non conclusive)...
