Thread: Is running lean safe?

if your running lean enough to throw a code...then you are not just a little lean you are VERY lean...be careful!

Yeah it's throwing a system too lean SES code. I haven't been getting into boost at all since I posted this lol.

If you know your maf is bad, unplug it and run off the pcm tables. At first the car will run like crap until it learns the tables. Running off the tables will most likely make you a little rich and safe.

If you are getting a lean bank code, then the pcm is telling you based off the O2's that it's adding more fuel than it's allowed w/o pushing a code. It's not necessarily lean.

Alright, thanks. I didn't even know you could run it without an MAF.

You bet you can. One of the first things in the FSM for maf testing is to unplug it.

Which cable do I need to unplug?
Theres a pic of my engine in the lounge if you wanna do some circling for my dumb ass
