Throttle won't go above 20%

TBatt

I had something similar happen to me and it turned out to be a bad connection to one of the throttle bodies. I had installed a Stillen SC kit with the A2A upgrade and the car drove fine for many miles and then suddenly it would go into limp mode while driving. Shut the car off and restart would fix it every time. I took all of the cable ties off and re-seated the throttle body connections. This time when I installed new cable ties I made sure to leave the wires a little loose. So far the problem has not come back. Check all your connections on the MAF and throttle bodies. I recommend disconnecting them and then re-connecting them to be sure you hear a click when they seat in the connector.
