Which of the nissan maxima is this. Year, engine size. This is where is the idea of patience comes in cos I could see in your post where you are already in need of the car. Was the tune up done? If the fuel delivery system was lean. Then let him go ahead with the engine tune up

Checking fuel pressre from fuel pump, spark plugs, ldle air control valve, air filter, throttle body, clogged up fuel injectors etc.

Let him check the idle air control valve . Let him check the throttle body. If dirty clean it up. That can cause this problem as well. Just treated this same issue on a pathfinder

are you sure it has one? guy just leave this matter...

mayor2013:
If it doesn't the scan tool would not throw up that fault error. " idle air control system " you better leave Nissan o

GAZZUZZ:


for this present matter, where you see idle air control valve?

mayor2013:


It is built into the throttle body sir

steveyen:


Thanks Costee.

This was left out because the car was starting and behaving almost normal with P1800 code on it.

mayor2013:
Let him check the throttle body. If dirty clean it up.

Costee:

That's one thing you don't want to do.

Costee:

Nope. Nissan removed the IACV from the Maxima after 2001. The term used for the TB function is Idle Speed Control System. And when it's out of specs you need Idle Air Volume Learning for correct regulation.

mayor2013:


Am talking about the nissan pathfinder 2003. And what happens in a case where you run a scan and find idle air control system lower than expected

mayor2013:


Why?

Costee:

Well-known fact. You risk a high rpm. The TB adapts well to the grit that builds on the valve over time; remove the dirt and the you throw the TB off balance. No problem once you have the tool to do the IAVL to "pacify" it.

mayor2013:


That's well known on a drive by wire system. Best way to clean is take it off the intake plenum or better have someone press the pedal for you while you do the cleaning.

GAZZUZZ:


This is nissan, you clean it, you find trouble.
