smelllikefumes Posted September 15, 2017 Share Posted September 15, 2017 (edited) 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 Edited September 15, 2017 by smelllikefumes Quote Link to comment Share on other sites More sharing options...
smelllikefumes Posted September 15, 2017 Author Share Posted September 15, 2017 SOLVED!! Was a wet Throttle Position Sensor (or valve). Removed it and ran compressed air through the opening and now the motor runs fine. Quote Link to comment Share on other sites More sharing options...
