SOURCE: Engine Idle speed

Yes that is most likely normal for your car. But there you could be other factors playing into the potential high idle, for example if your timing is off the computer could be compensating by advancing spark. When was your last tune up done?

SOURCE: 1992 volvo 940 has alectronic

It could be a fluctuation in oil pressure due to the cold temperature, or it's due an oil change with a new filter. The oil pressure switch might also be faulty.

Low idle


remove and clean the Idle air control (IAC) it may have carbon build up in it. make sure pcv valve is working properly. you can use carb cleaner to clean IAC valve. after IAC is removed, clean at throttle body side also. good-day!

Good day. My Volvo XC90 has check engine on, and the scan result is P2188. Can you explain code P2188 and what to do to fix the problem. Thanks


It means the engine is running rich (too much petrol) at idle speed. It probably has a rough idle now? The most common cause seems to be the Mass Air Flow - MAF - sensor at fault. It will need to be cleaned or replaced if so.

I have a 1997 nissan pickup with a 2.4l 4cyl engine and it idles rough. On idle it sounds like a V8 with a big cam in it, you know kind of lopey. When i drive it though it seems fine. The engine runs...


Possibly be a problem with the egr valve if it has one fitted I would check on line to see if your model was fitted with one it normally is the cause if car goes into limp mode

not a oo2 but maybe a IAC (idle air controll ) you should try and clean it with carb cleaner before replacing it.
