I'm throwing this CEL.
From what I've read, here are some possibilities.
1. Leak in intake tract after MAF (checked and triple checked, can't find any leaks
2. Vacuum leak (checked, gauge shows 20 vac)
3. Dirty/Malfunctioning MAF (how to clean/test?)
4. Bad/sticking EGR valve (how to check?)
5. Fuel pump (doubtful, as I can clear the code, turn the car on and the CEL sometimes comes on after a few minutes of idling
6. Bad front O2 sensor
Other symptoms:
1. Occasional drop in RPMs when idling
2. Spark plugs are due for a change soon (29K miles)
Any thoughts?
