Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hello. Is this an intermittent problem or is it constant? If it's an intermittent problem, there is a TSB that pertains to it. If it's constant, try first cleaning the throttle body with brake cleaner and a rag and a tooth brush.
Finally, have you checked for diagnostic codes?
Yes you can use carb cleaner. The TSB is a technical service bulletin. It helps us quickly identify common problems. When a problem is rather common on a particular vehicle, a tsb is often submitted. If the cleaning of the throttle body doesn't work, I can email you the TSB
While your at it, apply power to the IAC located on the side of the throttle body. See if it clicks.
Yes. That will work fine. IAC is the idle air control valve. It has a lead on it with a connector with a couple wires. It should click with power applied if it's not sticky. If it's sticky, it would cause this issue as well. Clean the throttle body first though. See if it fixes the problem.
here is an illustration.
sounds good. Thanks.
Sounds good. Here is a picture of it. Since you have carb cleaner, you can remove it and clean the carbon out through the holes on the mating surface. After a while, they get sticky and don't function nearly as well as they should.
The TSB is directed toward intermittent idle fluctuation, or surging. It indicates a bad connection at the splice on a black and grey wire coming from the computer and branching 3 ways going to the throttle position sensor, engine temp sensor and exhaust temp sensor. the splice is located on the top of the engine toward the back of the valve cover. If you would like me to email you the TSB, I will gladly do so. I would send you an additional service offer and you would provide your email address there.
It's not too bad. You would just have to either Re solder that splice, or check continuity at the splice. I'm sure once you saw it you would realize that you could easily handle it. Look for it when your checking out the idle air control.
Not a problem. I'm here when your ready. No rush.
OK. I'll be here. If I don't reply right away I'll reply asap. Thanks!
