I started my car up the other day and it was idling very weird. Revving up and down between 1-2 rpms. Started up again on my way home and the idling was even more dramatic. On my way home, codes threw off for system running lean on both banks of the engine. Took it home, cleared the codes, re-flashed the ECU with the original tune. On start up the idles immediately went from 2k to less than 1k, the engine began to stall out, giving it throttle kept it alive. At a glance the intake system seems fine, and i dont hear any leaks. These are the only codes i am getting. And honestly, I am leaning towards a clogged fuel filter. This has all come on very suddenly. This is because it simply feels like the engine is not getting enough fuel, and the issue has become more and more pronounced each time I start it, as if whatever is in the tank is making its way through the filter.

Was hoping someone could chime in. I suppose it could be the sensors, but again, im not getting any other codes besides system running lean on 1, and 2.

 

What were the DTCs exactly?

Did you check LTFTs and STFTs?

What is the fuel pressure?

 

p2187 and p2189. I have no way of checking those right now.

 

Your pcv diaphragm maybe leaking, 15min job

 

dennis black..

sounds like a small job that many of us would like to be able to do...

would you post info? directions? a link?

thank you!

 

Is it possible for someone to intentionally clog a fuel filter? I have a gut feeling there is some foul play involved.
