lost power in my z overnight. was driving fine one day and came out and car would barely run. checked all injectors and they are good. when we disconnect any injectors from the drivers side of the engine we do not get much rpm change. compression numbers are 1# 150 2#133 #3 150 #4 133 #5 151 #6 132. car seams to be running really rich. engine was rebuilt 5 years ago and has been running fine until now. changed ecu, coil packs, spark plugs, pdu. no smoke of any kind. did a vacuum test and all good. swapped mas air flow sensor. cant think of anything else to try. compression numbers in the drivers side are low but i dont know if they could be responsible for such an imediate problem??? please help!!!
