Chris the other day you suggested that I check my codes with the help of the FAQ section. I did and I just want to make sure I'm seeing this correctly. I got a 12 which I have had the battery out recently. I got a 37 which doesn't fit my year model(1990 318 tbi auto with overdrive) or maybe it has one which is the throttle lock/unlock solenoid driver circuit. I also got a 31 which is the evaporator purge solenoid circuit driver(whatever that is). I also got a 55 which they say that it is the end of codes. I did this several times and to my eyes this is what I saw, I didn't know that more than one code would come up at a time so I'm just asking if this is a normal sounding code readout. There was 27 total flashes and according to the pauses after reading in the FAQ section the above code numbers make sense.
