T350 holding onto the revs
Discussion
Following on from my loose battery terminal excitement, the car now holds onto the revs when changing gears. It also appears to idle a little high, say 1100 vs 900. It does it out of gear too, blip the throttle and the revs take a long time to fall back down to idle.
ECU relearning the settings, sticky throttle cable, something else?

Mines has done the same a few times, first time was after her winter hibernation, some WD40 into both ends of the cable sorted that out. It started again just before service last year, the WD didn't help so was tracked down to the peddle being sticky where it hinges in the peddle box, all the crap gets into it. You have to remove the box to clean and lube up the pin though.
Hope it's something simple and you get to the bottom of it.

When mine did this the Lambda's had died. Started as a poor earth but it killed them. Additional earths added and new sensors fitted and its all fine. Good job I run decats or it would have taken the poison pussies out too if left too long. only a problem under 3K revs after that the lambdas are open circuit I think

Thanks for the responses, the 3k rev thing does seem to apply so it may be Lambda sensors, but I'll check the cable n carpet n what not to.
If you have the diagnostics software its easy to see if the lambda(s) are dead, they show zero voltage and there is no switch trace. They also have a fuse which is worth checking before replacement, can't remember which it is. I know its 7.5A #36 I thinkIve got similar problem. Just started the car for the first time after its hibernation and the accelerator pedal is not fully returning to normal. Its not open enough to move the butterflies but its causes revs above idle.
WD40 to all pedal mechanisms but not fixed it. Going to try and lubricate the cable later but found so far that when I unclip the top of the cable its not pulling the cable back through completely.
Does this just sound a bit sticky or has anyone else any thoughts?
I also thought about a stronger spring.
