Out of nowhere yesterday I got a CEL and the code I pulled was P0301.
It was raining really bad in the Chicago area and thought it was maybe some water, But nope sitill not running correctly this morning.
I drove almost 150 miles in mixed traffic and about half a tank of gas. didn't notice anything till almost home at the end of the day.
I changed the Plug and tested with the OEM wire same. The plug did smell of gas.
I installed the Screaming Coil and Live wires last fall.
Had the 40k service done a few weeks ago with the Injector cleaning.
I did also test the oms across the 1-5 Secondary's on the coil and got a 09.01 which is well within range.
Now I'm starting and idleing fine. and at speed it also seems fine, but at idle under load, backing up or pluging away is is idling ruff.
I do have a 70mm Maf, volant CAI, Modded TB and the stock muffler replaced all been installed for a while. Running an 91 tune for the MAF on a SCT Xcal2. also nothing new.
Anything you guys can think of.
I am still under warrenty, but can't afford to lose the truck for a few days and no work.
Also if I do take it in, should I pull the CAL, MAF and TB and reflash to stock?
Thanks alot for any direction you can point me in.
