[198491132]

Good Day, I am reposting, lost my original post. My 1984 3.2 was running great in December. I filled up the tank in early December, added Stabil, and ran it down to about 50%. The car sat with one start in January. It now has a severe mis, back fire and unable to drive issue. Starts fine, idles good at 800, under throttle, will behave fine for two or three revs. The third or fourth time under throttle, I get the huge mis issue.

I have added a bottle of red line fuel cleaner and five gallons of fresh gas. The car is now down to a quarter tank, same issue.

Done so far:

Listened to the injectors, all six sound the same.
Tapped injectors to free up
Verify all wire connections from sensors
Changed dme relay, for kicks and giggles
Checked battery voltages
Unscrewed oil cap for vacuum check, ok
Secured plug wires
Viewed cap and rotor, slightly worn but car idles and revs 2-3 times before issue
Pulled air cleaner, look fine
New air flow meter 1k ago

Some folks got back to me with injector ideas. I am going to change the fuel filter shortly, as I have a spare, just to see.

Full pump is new with only a few thousand miles on it. Sensors have been changed out about 15k ago. Temp sense and O2 also newer.

I am thinking bad fuel, but would like your thoughts as well. I only have a quarter tank left, should I run it down or add a few gallons of fresh?

I made a video, but Pelican will not take my post.......if interested please let me know and I can send it to anyone that wants to help.

Thanks, Dave
