2014 running lean

2014 running lean

Postby ABar51 [OP] » Jun 29 2016, 1:38am

This is my first post, so go easy on me.

My 2014 Silverado is running lean, Lew states it's got an air leak. I've had it to several techs and can't find anything leaking from anywhere. I've crawled all around this thing, check it personally and with technicians around the air intake - the exhaust anywhere I've done anything and can't find anything wrong. Some things that I've noticed is that when at idle it almost stalls out on me and drops below 500 rpms. Sometimes when flooring it, it'll lose all power for a moment then will come back with a vengeance. Any suggestions what I could look for or what I could do? No engine codes ever show up when I run diagnostic tools on it.

Have you tried returning the truck to stock tune to verify its not just a programing issue?

I had a similar issue about 6 months ago. About a week after i noticed it, my 2014 tanked and would stall out. I could run it for about 1 min if i didn't gun it before it would die. Chevy towed it, and replaced the mass airflow sensor and it has been fine since.
