Car starts and everything works but idles rough

Apr 29, 2024

Hello guys I ended up get the new fuel pump and AN line setup for the assembly. The problem I have now is when I start the car all the DL come on and when it turns over the only one that stays on is the CEL the idle is rough on the car I 0ed the SACF 2(probably spelled wrong horrible memory) hooked the laptop up and checked the DTCs cause the CEL(was recommended to check for codes) was on and I’m getting “DTC 0012 Volume air flow circuit malfunction” I cleared and updated and it popped right back up. I’m new too this so I’m wondering if anyone knows what I need to look at I’d be grateful.

Thank you.

Do a google search for the error code. Could be the MAF, or connection issue to the ECU. Do you have an idle surge, or more of a stall?
