Thoughts on backfire?

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.

no zr-1 is immune from failing injectors

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

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."

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.

I have had my Accel injectors since 08. Never a hiccup.

When I purchased the car last year the prior owner had FIC injectors installed. I guess they didn't last long with the ethanol in todays fuel.

I've never heard ANYone say ANYthing that could be construed as ANYthing but +, about Jon, or FIC. I've talked with him, AND his help, and seen his address to customers on forum boards, with issues that customer THOUGHT would be fixed by new INJ's install, but were failed customer diagnosis, and I don't know too many business entities that are better, when it comes to CS.

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...

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?
