Need help please !!!
 

Ok guys here's what happened today...coming home from town car felt sluggish and when I stopped at red light and pull off the car wouldn't hardly move. RPM's didn't go over 1100, pulled over right then with my foot still on brake and car still in drive i pressed the gas and the rpm's didn't move at all. I put the car in park in foot off brake hit the gas and rpm's went up slowly, I then turned car off and restarted it and it did fine......until the next light. As long as the rpm;s don't drop to low car runs fine. I need help on this one guys, oh and no CEL or codes.

Check to see that your inlets and intake system are all in tact. The charge pipe likes to blow off (partial detachment). The intake plastic isn't the most secured either. Double check vacuum lines.

This sounds like limp mode. This happened to me going up a hill, from being stopped at a light. Not sure about it not tripping anything.

Please report back if it continues, mine never came back. I assumed it was something blown loose.

I pulled the codes today of P0120, P0121 and P0220

So do I need to buy new throttle/pedal or throttle body?
