Re: 2000 neon backfiring

Is the check Engine Light on (CEL) ?
Any local Auto parts store can pull the Diagnostic Trouble Codes (DTC) for free.
Bring DTC's back to your Thread in AF.

You are probably getting a misfire and raw fuel is being dumped into your catalytic converter causing the backfire.
