@greggbenchpress1 Mine was not a gauge problem. The gauge was fine the PCM was receiving the wrong temp

You retard it only sounds choppy becuase of the cam. But a bad ect sensor will for sure cause a closed loop scenario. I had that same problem with my foxbody mustang.

@Hekikahni Not sure if you know it or not but it does not mess up until about 1:20 in the video. There are 2 sensors on the lt1, one runs the guage in the car and one tells the PCM what to do. Your guage is right under the exhaust Manafold/Header on the drivers side head and only effects your guage. This has been fixed since Jan of 2010 and only cost about $12. The sensor used by the PCM is on the waterpump and will cause this problem once the PCM goes closed loop. Class dismissed!
