Check the coil packs for voltage , the cam position sensor and the throttle position sensor. Put a code reader on it and crank it so any new codes will come up.

Hope it's the correct one for the engine displacement. The best way to do this job is to go to an auto parts store and get the chilton manual for your car. It will explain all you need to know.

Backfiring is caused by either the firing order being incorrect or the engine timing is incorrect. generally backfiring through the carburetor is caused by incorrect firing order. confirm the distributor is inserted properly and double check firing order beginning with cylinder number 1.

Check your vacuum hoses. Holley aftermarket may not have as many vacuum ports as OEM QuadraJets, and you may have a vacuum line that isn't plugged into anything...or you may have a vacuum leak around the carb base gasket. Also, does the Holley have an electric or manual choke? Is it connected?

You have a vacuum leak. There is a rubber hose going from the transmission to the intake manifold. Check that first. The other thing you might try is to disconnect the battery cables wait 10-15 minutes and reconnect. This will reset the onboard computer that also controls automatic transmission.

Check all your fuses, they can come loose and get corroded on these cars. Give all the fuses a good wiggle to get rid of any corosion- and be sure they aren't blown. If it's not that, check your wiring harnesses to be sure they're tight.

I don't want to insult you, but did you check the fuses?
Check the bulbs?
Check to see if they worked on "high beam"?
(possibly the dimmer switch, if all the above questioned items were checked and found to be good)
Best of luck with it !

Just under the dash on the driver's side. GM always put them there, I think. They usually stuck out just a little from the very lowest panel on the dash. Post back if you need the code retrieval process and/or code descriptions, and I can give you a link. Or, what the hey, here it is:

  • Hi, I can help. Please see the diagrams I uploaded for your firing order. You did not list weather you have fuel injection, turbo or carburetor so I will list all 3 possibilities for you.

  • This is the firing order for a carbureted.


  • This firing order is for a fuel injected turbo engine.


  • This firing order is for fuel injection with out turbo.


  • If you have any comments please feel free to leave them here.
  • Hope this helps and thank you for using FixYa.
