Okay so my gas mileage straight dropped within about a month and it’s lost it’s power recently. Those 2 fault codes showed up and I had a crank position relearn done and cleaned MAF. It ran best it ever had in years and now it’s back to crap. Any help?

You ever actually figure this out? My problem was right behind yours! I replaced my throttle body being pretty damn confident it was that. I have no codes though, I replaced basically all of my evap system within the last year too, found a cracked pcv hose... yea not the issue. A couple other small things but I don’t want to keep hunting at this point.

If your going all out go get a fuel injection service done and make sure you get the actual service where they clean through the fuel rail.

Did the brake feel spongy at all? Like right after they put in the brake booster/master cylinder?

I’ve inquired about this before because one side was squatting more than the other. Tech told me they hardly ever fail and to inspect for cracks but I’m still wanting to do it because even when I’m on empty it’s squatting on the driver side.

Try relearning throttle position sensor before doing anything else, just YouTube it it’s so fast.

I have the same problem and the only possible answer I got is leaf springs. The other is gas tank weighing the other side down.
