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.

97 3.9 dakota when it's cold outside and I start my truck it'll start right up but idle down til it quits . Start it again and it will idle.. Go down the road and it misses bad until it warms up. After it...


Here are the most common causes of idle surge, rough idle esp when cold and stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

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.

Motor surges up and down it starts


I suggest you clean the throttle valve and the idle speed control valve on the engine.

Engine speed decrease when stert the AC


IDLE AIR CONTROL VALVE IDLE SPEED TOO LOW. IDLE SPEED SHOULD BE 750 - 850 RPM. IDLE SPEED NEED TO BE CORRECT OR IT WILL CAUSE ENGINE RUN ROUGH OR STALL OUT.AC COMPRESSOR WILL TAKE SOME POWER FROM ENGINE WHEN AC IS OPERATING.

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.
