The emmision warning light came and the car misfires on few occasions

Sound like a brake on warning so you don't put in gear and drive with the break on however a brake light should come on but it maybe Burt out

take it for a run on high way
high speed, low gear to clear the emmision

well i can not say its good for you to drive with it for a while because by that its telling you that you must change your idling sensor and your plugs or plug wires but when your car is idling or in immotion is there any misfiring?

hello there
Make shure you fuel filler caps is on corrrectly.Also water+oil filler caps have to be tight.
Then you could try mass air flow meter .
After try to have someone replace oil separator unit for you with the breather hose.

proporsche

could be the maf sensor for the back firing cond,the a/c and heat could be the blower motor,check fuses and relays









TIM........................

a blinking light means the system has detected a misfire in the engine. Have the system tested to see what cylinder(s) is misfiring

I just had the same problem, which I also had in another car, a Jag XF, this can be related to too much town driving, and you may need to take half an hour of motorway or similar driving at higher speeds to clear the problem from the exhaust system, and the warning light.

Sounds like the lambda sensor! for the emmisions

The warning light has two states. A blinking light indicates a critical problem with gaseous emissions from the engine that is likely to cause permenant damage to the engine, exhaust sytem or catalytic converter. A blinking light must be remedied immediately, and the car should not be driven in this state, at the risk of causing serious and permenant damage to the engine, exhaust and/or catalytic converter. Repairing or replacing these parts can be extremely expensive. A reputable garage or a Vauxall/Opel garage should be able to diagnose and repair the problem.

A solid (unblinking) light indicates a non-critical fault in the emmisions exhaust system. Many faults are covered by this light including failures in emssions sensors, temperature sensors and a variety of other parts. This usually results in a higher than average amount of environmentally harmful pollutants being expelled from the car, loss of power and/or gradual damage to the engine, exhaust and catalytic converter. While the car can still be driven with a non-critical emmisions problem, it is highly recommended that the fault is diagnosed and repaired at a reputable garage or Vauxhall/Opel garage.

try changing the o2 senser that will cause the car to run rich or lean
