Re: Thoughts on backfire?
That's what I have been told up here in FBI land.
I had a 1992 Nissan Maxima and the injectors on that car were well know for failing due to ethanol in the fuel. If I knew about the failing injectors on the LT-5 before I purchased I would have purchased a 1993 or later model year.

Re: Thoughts on backfire?
I suppose you are correct but I have never heard of a failing injector on a 1993 to 1995 LT-5.

Re: Thoughts on backfire?
Reached under the car and managed to tighten 6 of the 8 clamps (didn't jack it up yet, figured I'd try what I could reach quickly and see if it helped at all.) The 6 I hit felt pretty darn tight but I made them a little tighter; don't know how far I can go before shearing a bolt. Took it out for a quick spin and the backfire seemed less frequent but just as intense. To answer Dom's question, seems like it's primarily driver's side. If it isn't one of those other 2 clamps, I'm stumped. Marc says, "I would guess that we have a 50% chance that we could cover-up what ever is wrong by adding fuel during engine deceleration."

Re: Thoughts on backfire?
Headers, no catalysts, and a Corsa (no)catback is basically straight pipes with a couple of chambers for standing wave acoustical tricks.
I thought the Corsa was too loud with the factory manifolds and factory cats- I doubt there is much to be done about the intense popping. Usually conventional mufflers and cats muffle the lean pops to a common burble. |

Re: Thoughts on backfire?
I have had my Accel injectors since 08. Never a hiccup.

If you had a bad experience, I think you should contact him, and allow him to address the issue. And he's done so in the past, ON FORUM BOARDS FOR ALL TO SEE. ============================ KS; looks like you might have a couple of issues here; a little FSM reading (never fun, but highly informative) might lead to a common root issue solution, such as a shaky ground on an important / multi-ground connector...

Re: Thoughts on backfire?
Will an exhaust leak cause backfire, when he's got a good burn in the cylinders?
If so, what burns? HC's? Will HC's light up SES? Got SES there KS?
