Code 11 will mask all other codes until it is fixed.

Check your grounds at the intake manifold and the one behind the battery.

ok i will have to check tomorrow. do you think a bad gound could cause it to run like that

What about the one next to the inter cooler pipe on the passenger by side and the one on the manifold?

The grounds for the ECU are on the intake manifold. The fender point grounds the main relay. It's not a question of it making it run like that, it's a question of you getting stranded by the side of the road. Code 11 is a power interruption to the ECU...it's severe. That's why all other codes are not "displayed" until it's fixed.

ok so there was two grounds that were off one at the front of the trans and one at the back. my code 11 went away now im throwing code 43. what should i check now.

Code 43 is no starter signal to the ECU till 800 RPM...indicates a problem with the ignition switch or it's wiring. Pull the EFI fuse to reset the ECU and re-check the codes after you run it.
