87 5.0 AOD Speed density....
I've never had it popping/burping sound from exhaust till after changing Ignition modules and replacing bad connector to module...
It was really bad popping at 5 degrees base...I thought it might be lean condition....I bumped the timing to 10 to 11 degrees most of it went away but still some popping...no pinging....
I have no clue.....need help...
