everything has been swapped over to the fairlane engine from the old engine. the idoling is sh*t. its over boosting when I try thrash it just to move anywhere otherwise it will just stall. everything is the same from the old motor. I just dont get why its like this. im scared its going to blow up again. a scan tool got put on and a few faults showed up. it started reving loud and playing up. since that's been put in its worse.
