Hey everyone! Heres another little problem with my 86 firebird. When I first start the car in the day, it stumbles and dies out in 2 seconds. Start it back up, it stumbles, then revs a bit higher, then stumbles, then it revs up...etc..does this for like 30 seconds. Followed by rough idling. And now I get the SES light on and i scanned it and I got code 44. thats oxygen sensor-running lean. I just got the car 2 weeks ago and i did a tune up and changed the oil. the car was sitting for 5 months prior me buying it. Any suggestions on getting it to run more richer? thanks.

 

What engine is in this '86?

 

Sorry for forgetting to mention it. Its the 2.8l v6.

 

Update... I was browsing some sites and I came along one which gave more detail to this code...
44. Oxygen sensor lean
(Poor electrical connection, open or short in circuit; defective ESC module;
defective knock sensor; defective ECM.)

Anyone had experience with this code?

 

Bump

 

Sounds like one or more fuel injectors could be plugged from the car sitting for 5 months.

 

ahh..should I try and pour in some fuel injector cleaner into my gas tank? Or do I have to take them out and clean them? If so, how would I clean them?

 

Try the in-tank fuel injector cleaners first, with a tank full of good gas. You can not (or should not?) attempt to clean the injectors yourself. The other option would be to take the car to a shop that will clean the injectors on the car with a heavy duty solvent. Cost at a shop can be pretty expensive, anywhere from $75 (on sale) to the cost of a new set of injectors.

Use a good fuel injector cleaner. I've always used BG44K, but it's pricey (~$25).

 

Cool thanks...could a dirty fuel filter also cause this to happen also?

 

Yes.

 

Update: I didnt touch anything in my car, but I started it today and it ran nice...no rough idle, no stumbling....this is interesting...
