I test drove it yesterday with the bumper off and was rewarded with the same results. About 205 on the freeway and as soon as I got off it dropped down to 190-195.
I'm gonna order an oem tstat and oem radiator cap. Both are already new but aftermarket.
Does anyone have any idea why I can't set the base timing? Is there something else besides an improperly adjusted tps or a check engine light? Bad coolant temp sensor maybe...?
