Question 1 - Have you checked to make sure you don't need a larger alternator? It sounds like you might need one.

Questions 2 - Head gasket? When I blew mine in my girlfriend's v6, i saw white, blueish smoke.

1. Have you tried cleaning the IAC motor. I would start w/ that

2.The pop coulda just been back fire. How many miles are on the motor. Does it use oil at all between oil changes.

goto muscular musangs.com and look in the tehc articles, theres a through article on cleaninf the IAC, TB, setting base idle and TPS voltage, sounds like the problem in my opinion, whens the last time the timings been checked and the fuel filter changed as well....
