I've been a member for a while but never had a chance to post, so here I am. I got a SSV Manual, So everything started when I cleaned my intake filter, which is washable and it was all clogged up, car was running fine before I cleaned. I took the opportunity to clean the throttle body butterfly spraying some Carb cleaning into it while car was running. Because mass airflow sensor was off I got a engine light while I was doing the process, that was expected. Throttle Butterfly cleaned, air intake filter housing cleaned and filter dry, time to put all stuff together again. then I did: Clean the ECU error codes Unplug the battery for 2 minutes and connected back Start the car and left it running until the cooling fan kicks off Turn the car off and on again. Now a very weird thing has been happening, everytime I'm coasting or gliding engine revs up to 1100 - 1500RPM approximately however if while coasting or gliding clutch pedal is depressed engine goes back to idle, If I leave the clutch pedal car revs up again. If car goes to a complete stop for example in neutral after coasting with clutch pedal not depressed RPMs goes back to idle in 5 to 10 seconds after car stopped. I know its not right to coasting and that was just an example. Problem is: if any gear is engaged, car is moving and clutch pedal is not depressed car won't not glide and speed its kept even though my foot is off the throttle pedal. Does anyone know whats going on?
