Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Did you do the throttle relearn after replacing it?Also, is the check engine light coming on?
Sometimes cleaning the throttle body damages the motors in it.
Are you using a watch or clock with a second hand to do this? If you don't time it perfect it won't do the relearn
Ok, you might have a vacuum leak. Take some of the carb cleaner and when the engine is running, spray it around the throttle body and intake. If the idle speed increases or smooths out, you have a vacuum leak
I assume this wasn't an issue prior to cleaning the throttle?
