Hi all!

I’ve got a 1982 Trans Am 305 crossfire.

I’ve changed the spark plugs, new engine oil and filter, new fuel filter, and fuel.

It backfires on the injector, throttle body, and flames for a moment once you press the accelerator.

We have tried all we can think of, and it’s still running rich.

Please help. Any suggestions would be appreciated.

We have also turned to 10, 8, 7, 6 degrees with no luck.

Thanks in advance

Jess
