The truck is an 03 ranger xlt with the 4.0 SOHC v6
So finally the check engine light decided to come on my truck after 90,800 miles of service. I had it scanned at autozone, and it came up as "left cylinder bank lean" The truck runs and drives fine, i noticed no difference in the idle or anything else.
This came on shortly after the exhuast broke on my truck AFTER the cats. Basically all ive done with the exhuast since it broke is just run it straight out the side with some flex-pipe from advance. I love the sound, and it isnt too loud ethier, even without any muffler at all...unless you floor it. And with gas coming up on 4 a gallon...i cant afford to floor it lol.
Basically what im wondering is if the exhuast being such low flow with its current setup, is that some how throwing this code on the ECM? Doesnt seem likley but all vehicles differ. Ive had plenty of car with open exhuast and never had an issue.
Also i think the fuel filter has never been changed, so ima go ahead on do that this weekend. Though i doubt that would somehow cause only half the engine to run lean...but however unlikley im sure its possible.
