I am not running a thermostat, my stock radiator can barely keep up with the high. compression of this engine as it is.

I will look into the TW sensor tonight. Also, i noticed today that the single pin water temp sensor next to the TW sensor wire is broken. Would this sensor being offline cause this type of issue? I believe it is the one that tells the ecu how to adjust timing.

correct? thanks for the tips guys
