Replace the fuel & air filters, check and replace all spark plugs if necessary, and clean inside the throttle body. Then check the intake system from leaks, using a carburretor cleaner spray, engine idling. If there are not revs raised, the intake system is OK. Also verify the idling regulator step by step electrical motor actuator. Replace it if necessary.

2007 V8 diesel sport. Missing badly at idle (650 RPM) when cold, runs smoothly if revs raised to 1000 RPM. Does not appear to miss under full power, and will generally run smoothly at idle when warm.


most likely bad injector tips
have them serviced and raise the idle to 750 rpms as the lower idle speed may not be raising the combustion pressure temperature to ignite badly sprayed fuel ( diesel has to be atomized not squirted )

My suzuki swifts fan comes on even when cold the car suddenly revs to 1000 from 800rpm. I can shut her off and it revs normally for 2 mins then the fan kicks in and the revs go up any suggestion plz


A sticking cooling fan relay ! What year is your swift ? The ECT - engine coolant temp. sensor is an input to the PCM - engine computer ,when the engine temperature reaches 213 degrees ,there about ,the PCM will supply a ground to energize the relay turning on the cooling fan . Also when this happens the PCM will raise the idle RPM to compensate for the load on the engine . Do you know what a relay is ? It is probably located in the under hood fuse / relay box . It will give you a diagram in your owners manual >

Hi VW fans a 2007 Jetta 2.5 liter with a


The problem that you describe is in no way normal. That six second lag that you describe is more than enough time to get you into a serious accident. I have experienced a similar issue on Mitsubishi automobiles. When the hold down on the throttle cable is holding the cable too tight (not enough slack in the cable) or if someone has adjusted the throttle cable to remove the slack causing it to be too tight it will cause a fast idle lag like you describe. On several fuel injected cars stick and automatic I have experienced the engine rev issue you describe. Every time it was fixed by setting the cable tension back too loose.
Another item, if the cable slack does not fix the problem, fuel injected cars are fitted with an Idle Air Control Valve (IACV). They are located on or by the intake throttle valve. The price range for most is $30 to $100. If they malfunction they will raise the idle speed by letting too much air go around the throttle valve raising the engine speed even though the valve is closed. You can check if the throttle cable is too tight yourself. The IACV may have to be checked at the dealer. Only the dealer can tell you if the problem is covered under warranty.
As always check to make sure that there are no loose vacuum lines under the hood.

1994 C220 mercedes stalling problems


check your main harness wire. The harness wire becomes brittle and will eventually short circuit your car. Stalling and hard starting is the initial symptom. If not replaced soon, your car will smoke and eventually affect your computer box

Mitsu Montero Sport '02 engine stalls but not when air cond is on.


hi there. the reason that the engine idles good when the air-con is engaged is that ussually all vehicles nowadays have a vacumm advance mechanism. this is triggered mainly by a electric solenoid valve which is also attached parallel to the source supplying power to compressor. a small vacumm hose with a diameter like a common pencil or ballpen case. its made of rubber and it runs from the alternator vacumm pump then to the solenoid valve and to the vacumm advancer unit attached to the injection pump throttle. this system raises the idle a tad higher.

if your montero runs completely normal and you experience no other problems with your engine except for your present problem, then the solution is just raising the idle a little higher. if your montero is equiped with a RPM guage on the dash, try adjusting the idle to around 800 rpms. it would be healthier for your car if the idle raises a bit when you engage the air-con because this would compensate for the added load on your engine.

hope this helps.

Idle out of control.


check all your vacuum hoses and the throttle body itself for a vacuum leaks if the hoses replace as nessasary if to check for throttle body get can of carb cleaner and spray around base of throttle body and sides not in it if idle raises you have a vacuum leak goto a good parts store and ask for a rebuild kit don't goto auto zone or advance they don't carry them

1994 Mercedes C220 A spontaneously switches off when engine cold


early production 202 chasis cars had an updated overvoltage protection relay modification. I beleive it was to remidy a no start condition. From my experience there was a problem with the o2 senser heater circiut that would cause intermittent stalling when cold. There should be codes stored in the engine diagnostic modul even if hfm has not reconized a problem. i would have the scanned for codes. If none present I would purge the intake manifold(clean with special cleaner inducted into manifold via vac, port to remove all the carbon buld up and have the maf senser electrical porion cleaned. It would be a good idea to replace the front o2s with the mileage you have on vehicle.The heater grid is also located internally in the o2 senser. Hopefully you maintain your vehicle and have changed the sparkplugs and fuel filter according to service specs. Good luck
