96 blazer 4.3
Hi guys I have a 96 blazer that starts and idles fine. If you eat into the throttle it's fine unless there's a load on the engine or give it quick throttle in park it sputters and backfires it's got good fuel pressure. Checked inside if distributor and cleaned contacts. On scan tool while in throttle timing advance goes to -40 I feel that's too much. Any help is appreciated thanks
