I have seen a lot of posts about this recently, but none of them seem to cover my problem.
I have done the TH fix and for two years it has been fine, recently the throttle has been hanging very badly sometimes between shifts. The rpm's will drop to 2000-2500 and stay there for a few seconds before dropping further.
The car idles perfectly and I can not get the rpm's to hang while sitting still, only happens between shifts. My throttle and cruise cables appear to be working properly.
Any suggestions or help would be appreciated.
