    wanting my pile to run
  1. I am running the stock ECU and 83 harness. I'm also confused about the absence of the coolant temp sensor. I'll take a pic to make sure I'm not being an idiot. I have a multi meter and am going to test the coil today. I'll double check my AFM is not stuck as well and I'm going to remove and dry my TPS as well. I'll report back. thanks for the help
  2. Sorry I should of mentioned that I had to get a tow home. The car only idles for less than 10 seconds and doesn't move. The throttle doesn't do anything. What do you mean ohm it out? Just test it with a voltmeter?
  3. Both my fuel filters were changed a month ago after the car had been sitting for some time. They don't seem to be clogged and I have good fuel pressure (30-55). I posted somewhere else and they also said ignition coil. Would that cause the leaning out when the throttle is applied. I'm going to look for a replacement to just be safe and check it off. Also my car doesn't seem to have a water temp sensor. Could this been deleted by the previous owner. It ran fine for the past two years without one. I thought they were necessary for the ecu like the AFM is.
  4. So about a week ago my car started to have issues when it got up to temp. It would originally start, idle, and run fine, but after the car began to get warm it would lean out like crazy (have a wideband installed) and there would be no response when throttle was applied under load. It did this for a few days until it decided to completely die on my way home from the gym. After a few minutes the car would start and idle lean on the side of the road, but then die immediately with any throttle (not under load). The engine is from a 1983 280zx turbo. After a little bit of research I'm wondering if it is my Crank Angle Sensor in my distributor, but I'm still very confused. I don't think it's a wet Throttle Position Sensor because I had that problem recently and I removed it/dried it out and the car ran fine. Also the symptoms are different due to not even idling rather than failing at 2000rpm. Short video with symptoms: https://streamable.com/nn9ls

    (noob) 280zx turbo engine sputtering popping wont rev past 2k rpm

    SOLVED!! Was a wet Throttle Position Sensor (or valve). Removed it and ran compressed air through the opening and now the motor runs fine. Ordered a new connector since I saw some corrosion on the leads.
  6. Hello, I went to drive my car to the gym this morning I it is running horribly. Yesterday it ran perfectly fine, built boost seemed normal. It starts normally, but then starts to get slightly choppy and when I rev it it wont go past 2k rpm and is sputtering and popping all over. I have a wideband 02 sensor installed and when I start to rev the engine, the gauge goes crazy and reads its maximum (- - -). I disconnected the 02 gauge last night when trying to mount it a different location, but I thought that had nothing to do with the engine since I'm running a stock 83 engine and management system. (Previous owner was about to megasquirt, but sold it before finishing). I disconnected this connection and tried to rev the engine and seemed to be running early identical to when it was connected (barely at all at rpm): https://imgur.com/a/q7at5 Small Streamable link (44 sec): https://streamable.com/nzztz
