I'm looking for someone who has experience with working on and tuning L36 3800 engines in the Chicagoland area.
I have been dealing with a lean condition that is zapping my fuel economy and engine performance.
No one can seem to find anything wrong when there's something clearly causing this.
Please contact me and I can give more details.
Thank you.

Any vaccum leaks at the PCV line?
