1995 Volvo 960 idles rough, Emission Control light on dash is on

My 1995 Volvo 960 struggles at idle speed and has a miss at lower road speeds. The emission control light on the dash came on. Can't get it off. What do you suspect is the problem? How can I clear the light?

Possible intake gasket leak causing a misfire, or plugs or coil causing a misfire. each cylinder has its own coil. You can hear the vaccuum leak with your ears under hood if gasket is bad. Check eng codes at advance auto prob for free. If it has misfire codes only, prob coil or plugs. If misfire with fuel trim, prob gasket.

Is the check engine light on ?
The idle speed problem could be the idle air control valve, and the rough running problem could be fuel pressure or dirty injectors.

5.7 6 speed. Just started running rough miss firing at idle and lower speeds. Throws no codes.


Check for plug leads touching each other. Check for moisture in distributor cap if you have one. Check plugs and replace if necesary

It could be a fuel problem, but in most cases the rough running would continue at road speed.
You could certainly change the fuel filter and see what happens.
A rough idle but no problems on the road would point to a vac problem or maybe a burnt valve. A fuel or ignition problem would be at most speeds including when you put the engine under a load.
Its possible to have a faulty injector on one cylinder that is bad enough to cause a miss at idle but smooth out on the road, but that is a rare occurance.

95 volvo 960. rough idle which feels like a misfire but runs well above 1000rpm. Code 231 comes up once in a while even when 02 sensor has been changed.


Check for a vacuum leak. Could be a loose or broken hose. Also check the intake manifold gasket, they leak quite often. This would show up at idle only.
