I have checked the grounds, new plugs, new wires, New MAF (and the code came back). No luck. Things were great, before i went to the track What else should i check? Thanks.

Well I' trying to figure out my p1637 code right now. I guess it can be an aray of things. I'm going to start by checking all the connections to and from my alternator, as well as my pcm. maybe something got loose when you were at the track? i hope its just that.

Thanks Tootall. Anyone have any ideas on where to look to fix these? Like I said. I put a new MAF on, did the plugs and wires. But now im at a loss.

if it has a bunch of miles . . . clean the top end with Sea Foam.... intake and gas tank only, . . . nothing in the oil.

If it's a bunch of miles, the fuel pump could be weak.

humm nice . . . .


some may be tune related. If you have a big cam, then turn up the mis fire count.

The EVAP stuff - I'm guessing that you're not running that any more, so have that set to "no report"

MAF - if it was tuned and the tuner didn't put the re-cal numbers back in, it going to fail, or it's just not plugged in. Are you on a Speed Density tune? If you are, then it's not needed.

Alternator - I have no idea. Check your wires . . .

Just had the tune done last saturday before i went to the track. We spent 6-7 hours on the street tune with a wide band on the car. Everything is pluged in, and it has a MAF tune with the re-cal done. Im going to check the wires (ive gotten a new, bad wire before). The evap im not worried about. I dont know if the tuner messed with the mis-fire count.

The Alternator, im going to check all the wires and make sure that they are good.

The coils have 184,000 miles on them, so im going to get a scaner and see if they are firing right.

Thanks for the help.
