2000 SL1
Default went from p0301 to p0304

i have a 2000 SL1 had the faulty intake gasket problem causing misfire on cylinder 1 ( p0301 ). changed gasket everything was great after that for a month. Now i have missfire on cylinder 4! im stumped drove around all day yesterday just fine. Startedthis morning with ruff idle and almost immediate code.

compression is good all above 180

just replaced plugs and wires when i did the gasket and cleaned coil terminals at the same time did ohm test on coils checked out ok

fuel pressure was good dont remember the exect numbers but i know it was within peramiters at the the time i checked it about 2 months ago
