Yea I dont think its the coils either, settings may need to b adjusted a tad but not the issue. I checked everything again after lowering the steps for the fan cuz that did not work, so I adjusted the throttle plate closing it until the idle speed and timing adjustment in the data stream were in the correct range. now the only time the idle isnt correct the tps reads .39% which is not often and ive never seen the tps read like that so I was going to adjust that, I think the bolt holes come slotted for adjustment. Its been to cold to find motivation for that step :). The terminology always gets me, the "definition" Is the XDF correct? If so how complicated is it to add?
