I'm also having a high idle situation at times, and it's starting to happen more frequently. It appears we all have VE autos (not too sure about Bryan's) I've been looking into this problem for a short while and I'm thinking it might be the TPS, reason being the TPS has a off idle and WOT switch along with the usual potentiometer for the different position of the throttle. Maybe somehow the ECU is getting a signal from either one of these switches thinking that the throttle plate is off idle when it's not. Also with mine, as I'm stopping at a light in gear I can feel the engine wanting to keep reving (kinda like power braking) and sure enough if I select neutral the rpm will raise to 14-1500, but if I tap the throttle the rpm lowers back down to about 7-800 while still in neutral. I put it back into gear and it idles fine until I come to the next light where it happens all over again. The TPS is listed for about $150 at the dealer, this is why I'm trying a few different things first along with Nismo suggestion. Another thing I've notice is that my 1-2 upshift happens rather quickly with light throttle from a stand still, not quick like performance quick it's just hard to explain. I've never notice this before. I don't know about you guys, but I keep my power/comfort switch in auto mode and I'm not too sure if it makes a difference. I also have one of Don's VB and I agree with James, I've had his VB for about 15-16K and this problem just recently started to happen.
