Message	I did all the work myself, done it a few times on my other Z's. I'm sure the timing belt is set properly and tensioned properly. The valve timing will be off by 0.5 degrees from decking but that's it, not enough to cause interference. Ok let me rephrase the "freewheeling", it sounds like a car cranking over with the coil disconnected. Some resistance and I can hear valve events in the exhaust, but definitely no fire. Also, ECU gives me code 55. I will check some voltages around the engine bay and put some temporary grounds in to eliminate that. I am also trying to find an ECU and PTU in NorCal to borrow.
