Guest donmobile Posted August 10, 2006 Share Posted August 10, 2006 I have a 81 280zx turbo and got it from a guy for 800 bucks!!!!!!!!! car runs great but has had a miss and thought it was just the same old ♥♥♥♥ plugs wires cap. Anyways have put ajustable fuel reg with gauge and bunch of new stuff in the car and car still missing so went to the track and the miss got really bad before the car even got off the trailer it was small at low speeds before and now the car just loses spark like someone is turning the key on and off saw this on a timing light. air flow meter and fuel press and everthing is good but spark is coming in and out new coil too. can someone tell me if this could be crank angle sensor and or ignitor problem because car runs great but then this sparkcomes in and out sometimes and its like almost a short or something. alsoput a timing light on the cars coil wire to see spark coming in and out also could get timing to chage at all no advance or anything when you turn the dissy?
