6211, BIG BACK FIRE....1997 gsx
Posted by sadc, Jul-19-08 11:25 PM
I have 97 gsx.....So its going to have been the 2nd time swaping out the alternator with a 1g alternator on my 2g car. I used this method http://www.dsmtuners.com/forums/newbie-forum/233232-installing-1g-alternator-2g-merged-5-08-a.html post number 7

Anyways, after I swapped out the 2nd time turned on the car and everything was fine. Changed my spark plug wires (forgot the brand) Instantly when I changed them, turned on the car I heard a loud POP. And from there on in I had no boost and low power. Smelt unburnt fuel. So I thought it was my spark plugs, went to checkers to buy some
Went back to my car and turned it on and still the same. Also theres hesatation when I gas it. So looking at my FPR theres a guage and its reading around 42-45 When I gas it, it goes up to 50ish. Looking at my boost guage it reads -10hmg at idle when gas'ed it goes up to 0hmg then drops to -20hmg then goes right back to -10hmg. Anytime I gas it a few times it backfires. Pretty dam loud. Like someone getting shot. Any ideas ppl?

What are you tuning with? Seems your car is pig rich. Also run ngk plugs.

did you try putting the old wires back in? Or maybe try another set?....
Car ran normal, you changed the wires and it ran like shit. Why would you even think it something other than the wires?? lol

While you're replacing wires, I would put in some plain old NGK plugs as well (not platinum or any other fancy "amazing" plug). Everything else sucks in my opinion.

Well, this might or might not help, but judging from the vac gauge, and large "pop" sound, you might have had an intercooler pipe come off. i'd do a boost Leak Test or at least look everything over. It could explain the richness aswell. the car is still seeing the air enter the motor even though its not actually making it into the engine.
