Sounds like you gummed up the IAC when you cleaned it.

Let it dry.

And no more spraying the IAC port.

kk this was done last night now i just changed the idle air control motor and same thing
found renix fuel injection service model
tps voltage corect
any other thing i should check

Try squeezing the MAP sensor and checkthe small vac hose to it. If that doesnt work, check the 'cold start solenoid' - make sure its plugged in. Did you clean that too?

I had a prob. after cleaning mine, turned out to be the vac. line for the MAP. make sure it is properly connected.

Am not familiar with 'cold start solenoid'. Is there another name for it and location?

just checked map by pulling vac line off and idle went down

yes please more info on cold start selinoid

what is a good scan tool for these engines

After replacing the TPS and Cleaning the hell out the IAC and TB and letting it dry, I seem to get a vibration from the transmission housing, but only when the car is in gear. Park or Neutral and it goes away. Its on a 2000 XJ. Im stumped. Does the TPS or IAC have any effect on the transmission? Someone told me to check the torque convertor bolts. Are there 4 bolts on the outside diameter of the flexplate? Do those normally come loose. If so, could that be the vibration I feel?

Word of note, when I was cleaning the IAC, I turned it out of adjustment. It still idles just fine at around 600 or so. Could turning that IAC cause the vibration im feeling. Only reason I ask is cause it started after that happened. Is there any connection between the IAC and transmission?
