Ok I have been very busy with things and haven’t really had any time to play with the motor in my vette(97). Ever since I had the starter changed at a shop down here the CEL has been on.
It runs like total shit, so I finally pulled the codes. There were about 6…lame. I noticed that the shop didn’t put on the Air Pump shit on so I had to connect that, which cleared things up a lot(5 codes), but still runs poorly. Now it only has one code P0174, lean bank. I can’t seem to find any exhaust leaks or vacuum leaks, but they could exists I guess.
What would be your next move? I’m thinking about just buying 2 new O2 sensors. Does anyone know the “best” aftermarket O2s to buy?
I do not want to take my car back to the shop to allow them to “fix” it. I’ll just suck it up and do it my self. Plus I figure the car is almost 12 years old now, the O2 could be bad right? But would it give a bad O2 code?
Oh I have been busy doing some interior mods to the car finally…
Removed all sound deadening material, stock seat belts, about 15 lbs of dash metal bracing, some trim parts…trying to get this piggy on a little diet!! I’d love to get it to 3K lbs or so.
I’d check your MAF 1st. Usually in my experience, when you get a rich bank or lean bank code it’s the MAF. I don’t know if you can clean those or not but if you can I’d start there. If the O2 goes bad it usually throws some kind of code relating to the O2.
lean bank isnt entirely clear on what it could be, possibly O2s or MAF, etc, or possibly not getting enough fuel, ive heard of ppl simply replacing fuel filters and doing tuneups and the code stays away =) try the cheaper things first
I had bank lean on my civic and (hopefully) it is the cracked manifold leaking. I am also changing the donut gasket right before the cat as it looked a little loose.
