i just got done puttin on new headers on my maro, and it sounds and runs great except after a about fifteen to twenty minutes of driving if i come to a stop it will die on me, but start right back up and usually drive and die agian ten minutes later or so, i am clueless as to what this could be bc of the fact that it does start back up any suggestions please?

 

That sounds a bit like a sluggish IAC.

 

Plugs gapped correctly?

My ole dodge does this sometimes, Gapped out plugs solved it.

 

what is an IAC?

 

they should be gapped correctly, they are special shorty plugs b/c of the headers, but i will double check them!! it only dies after i have been running it for atleast ten minutes i thought maybe an overheating problem but temp gauge says its good!! and i just put in new thermostat
