Driving down the freeway today. All of a sudden I hit the throttle car starting feeling like it was sputtering, kinda shaky everytime I hit the gas. Check engine light comes on and I get a drive train warning. At idle car shakes and it's giving me these codes. First time in 2 years it's done this. Any idea?

Have you done some basic physical checks?
  • Check all loom connections are secure
  • Check for split or detached intake hoses

were you able to move to the side of the road, park. turn off car, wait a few, look under hood, check for anything... turn back on? How did car behave afterwards? reason i ask is: i had this happen a few weeks ago on JB4 map 1. car started bucking. pulled over turned her off. waited a few mins, turned back on w/o JB4. drove home just fine, no errors thrown. took it to dealership, couldn't read any codes. drove it a few days w/o tune. now i'm back on JB4 Map 1. no problems.

Yea got off the freeway, let it sit for 10 min, checked to see if I could see anything loose or not connected. But same thing. Starts up and its slightly shaking, still in limp mode. Same codes

What's your ethanol content at? I put too much e one time and got a bunch of errors. They went away after putting in gas and bringing the e-content down.
I pretty much always keep it right under E50. currently at 44. but i've gone over a few times. so maybe the injector is done. I'm just going to try replacing the injector. I did put some 91 in this morning and drove to work but the problem is still there.

I'm thinking maybe its the injector and why it feels like i'm getting a misfire in cylinder 6. So going to start by replacing the injector and seals
