wandering /high idle
OK since I had the loss of my TPS due to a short ( which is fixed) I now have an odd idle problem sometimes I start and it shoots to around 2k other times 6/700 or 8/900 I am burning through fuel at an alarming rate and don't think it is totally due to the cold weather all sensors look normal
Have 0451,1447 codes for emisions ( waiting on new fuel sender) doubt they are causing it, any ideas??
Please, rather not have the engine grenade on warm up

Black Box Solutions Nanocom but it's better suited for newer Rovers because of all it can do for them. It works for our antiques but not as much functionality for the price and aint cheap but it's less than an Autologic. If I'm not mistaken can't PT do the resets with the ECM off the truck?

Did you ever get to the root cause of the high idle problem ? I had a chevy pickup that had the same issue, turned out to be a leaking TB gasket. Of course, the reason I ask is, my 98 D1 started doing the same thing today. Random high idle at startup, around 1500 -1800, when cold. Not all the time, but enough to be noticeable and annoying. Sometimes it settles in by itself after a few minutes, sometimes it won't and takes a couple restart cycles to get it back to normal. And when it does reach normal rpm, there's some hunting going on. I'm looking at TPS, VSS, MAF, fuel trim, 02, etc and everything looks normal for that level of RPM & temp. No apparent vacuum or intake gasket leaks. Cleaned IAC. Voltage is rock solid 13.6, on UG and verified with meter. Hope you have the silver bullet for this one cuz I'm stumped.
