I'm at wits end trying to figure out what is the matter with my Foci. Lately it has been running VERY rough at lower speeds.
It's a 2000 SE w/ 2.0 SPI AUTO.
It spits and sputters then it will "catch" and take off. When this happens you can smell a bit of gas in the cabin. Once it takes off, the miss isn't there (much). You can cruise along at 80-90 MPH no problems. The issue is at lower speeds no matter the engine temperature.
Stuff recently done...
- Hollowed out CAT... Was glowing cherry red EDIT: Cannot afford a new one right now.
- New plugs
- New wires
- New fuel filter
- Used ignition coil
OBD codes P0102 (MAF circuit low) and P0302 (Cylinder 2 Misfire) *On both coils
Oil on Cylinder 2 plug, rest look brand new
I've checked for vacuum leaks, can't find any
I've checked the wiring to the coil
Spark tested cylinder 2 and it has good spark
Have not compression tested but I'm not sure if it's needed??? It also seems unplugging the MAF makes it run a little different and sometimes kills the engine.
Also, I've pulled power to each injector as its running and 1,3,4 kill the engine however, 2 doesn't.
