So, my service engine soon light came on. Hooked my computer to it, and reads that it's running too lean. Also, rough idle occurs off and on, while in motion and while parked. My warranty has expired. I think maybe a vacuum leak or dirty MAF? Help would be appreciated! thanks!

A P0174 lean code for bank 2

I have recently powdercoated my plenum so it was removed and put back together but i double checked everything all the hoses are securly in place. I'm really lost.

Any help would be apritiated.

any mods to the motor? lean conditions r usually from a vac leak, most common is tears in the intake boot from being removed, there small tears but they may throw a code

Sounds like a leak post maf. Clean the sensor, air filter, button everything back up tight, and reset the ecu.

It could also be the pcv valve. Fairly common issue on these cars.

check for a vacuum leak along the gasket of the plenum, use either brake cleaner or propane if the car stumbles, bam theres your leak!

when i start my car when its warm the idle drops to 0 and almost turns off but jumps back to idle. in some cases it does turn off. this only happens upon start up. any ideas?
