Should I disconnect while it's running? Is that safe?
Also, can I use WD-40 to clean the MAF sensor or only to check for more vacuum leaks? I'm going to take a look today when I get home from work.
If the car shuts off when I disconnect the MAF sensor, does that mean it's still good? If it runs better, that means it's bad?
It's just idling a bit high now at 1,100 rpms instead of the normal 775.
