I have an 04 early build that high idles when it wants to. It first happened with my SRL+ tune. I have been running the SPD and it doesnt do it with that tune. I took her back to stock to update my SCT and change the tunes on it. I have been driving her stock for 2 weeks now and it will High idle at random times. It will NOT idle down if you hit the brake. Has anyone delt with this before? It is driving me nuts. It high idled for 15min today after an 1hr drive. ECT and EOT both were at 189 at that time. I cant figure out why.
