Greetings,
If i stop and start it a couple of times it settles down to a reasonable level-- some mornings it will jump up and stay at over
1500rpm-- i can pump the throttle but to no avail-- it has to be restarted to cure it. The high idle can show up anytime.I replaced the TPS, but still happens. ( I did replace IAC, TPS, MAP, CCV and the one beside the MAP sensor last year. So the sensors are only 12 months sold) I also took off the TB last year and completely cleaned it. I had it idling smoother than the day it rolle doff the line.
I did replace the TPS last week but it still has problem. I did pull the IAC and it was clean.
My next move was to try the MAP sensor-- maybe the little hose has split or something.
It doesn't happen all the time, but something is not right.
Any tips appreciated
thx, james
