The car has a h22a swap in it and the electronics arnt wired the best. But when my friend got it it was running fine. about a week ago it began sputtering hard and stalling he has not changed anything on it. were lost we thought that some of the wires wernt connected to the ecu right, so we got a diagram and check the wires that had anything to do with the vtech solinoid. Nothing worked... were at a loss for words and he needs the car running cause he is stuck at my house.
