sputtering/backfiring
this am when warming up the my 87 Max before going to work, I was noticing that it was sputtering/backfiring until it got up to temp....just wonding if anyone has had any experience with this....the noise that is it making not loud at all, just sounds possibly like it is missing every once in a while....very low pitched like "thoooop" "thooop"....lol thoop....any help would be appreciate...I will probably just change the plugs and hope that helps.

My car will make the light thoop sound every now and then when cold. You can probably do some timing adjustments and tune up. Also check the operation of the EGR valve. The air regulator could also be the reason it's doing that. As the frequency of the sound is excessive, you probably won't have too much to worry about.

ok thanks, I plan on checking my ECU tonight for any codes...I imagine I will have a few 
I am also going to do a tune up tonight...I just got oil/filter, air filter, plugs, wires (advanced auto brand?)...so hopefully that will smooth things out a little bit...if not I will look into that air regulator

Oh yeah, be prepare to curse at the oil filter location....it's on the back side of the motor. I guarantee a PITA to get to. :P What kinda plugs you get? I usually like to stick with NGK stuff for the ignition myself.

I agree its an easy spot, to a point. Sometimes theyll come out easy from the top other times youre ready to curse at it.

Read Pkfinn's post and link in the "sticky" section on the air regulator. That air regulator acts like a choke, mine could not be fixed but new one only $65.

Curse at the oil filter, that crack me up. Well I know how much it's a pain to get there when you have a hot engine.
