91 245. I'm chasing an issue. My wagon has quite a drag/hesitation until maybe 2000rpm or so (don't know because there's no tach). Seems to get a bit better after it warms up. Below is everything I have done as a possible remedy:
- Tune up (plugs which were correctly gapped, wires, cap/rotor, air filter)
- Both fuel pumps and filter
- New seals and caps on all injectors
- Replaced a couple suspicious vacuum lines
- Swapped a good MAF from another 240 that runs great
- Swapped ignition coil
- New FPR
- Retimed
- Intake hose has no holes
I checked codes and had 3-2-2 (Mass Air Flow sensor burn-off signal missing or faulty (MAF wiring fault). I cleared it and it doesn't seem to have had any effect.
I keep thinking vacuum leak but I just can't seem to find any leaks.
