Have a N/A starts fine most of the time and rusn fine for a while then all of a sudden it just starts putteringt and backfiring. Some say its a loose connevtion, some say its some 2 dollar that cost like 800 dollars to be installed and some say the stereo was removed and there is some wire that is not there or conflicting. Any ideas?

 

I know you have a bad coolant seal so it could be that. Are you still overheating?

I remember seeing pictures of your engine bay. clean that **** up. Did you get a blow off valve? replace all those nasty vac lines and comb that thing clean god dammit!
