okay so my car seems to be having a throttle hang issue. when i shift the car will stay at the RPM i push the clutch in at for like 2 seconds.
but heres the kicker. sometimes the car will stay at the RPM i push the clutch in and not come down, and its kinda like the car is on cruise control. it will just stay at that RPM. to get the RPM's back to normal, i have to kinda give it full throttle for a second, then the throttle will not hang and idle will be normal.
why is this happening? is this something in the ECU? the car is stock ECU speed density tuned. i have tried cleaning the IAC, throttle body and checked to make sure IAC is working. i have also set the idle using the evoscan IAC mode and reset the ecu. checked for boost leaks and all. everything checks out...i have no idea what to do to fix this.
if someone would like id send them a copy of map and they could look to make sure everything looks okay.
It loops around and into the throttle wire clip on the valve cover right?
I was going to say if you have re routed the cable then it's been known to cause more friction in the line. But even in the stock location its possible for the wire to gain friction in the cable over time. Whats the odometer at? You can inspect and lube the wire with something like white lithium. I've seen this problem at least 3 times.
i cleaned the iac with cleaners you can only get if you work for a dealership. its made to clean carbon out of the TB and engine. its what they would use if you paid $300+ for the service. i dont know the name of it. but it works
the iac is clean and im assuming it works because when i click the idle adjustment mode in evoscan, my idle changed drastically at first. then i fixed it
