How's your coolant level? The intake manifolds on the 3.8L engines are prone to breakage at various locations causing coolant leaks into the crankcase and vacuum leaks on intake ports.Removal of the upper intake manifold will be necessary for inspection. Also, check for vacuum leaks at various locations on the outside of the intake manifold using WD-40 or brakeclean/carburetor cleaner sprayed hoses, non-electrical components, at the base of the manifold etc. As for a faulty injector, not likely but if you suspect one you can always swap the suspect injector with another on the engine and see if the misfire follows the injector. Just be sure to relieve the fuel pressure before servicing. Hope this helps.

Spray the intake with carb cleaner to find the vacuum leak. Check where the EGR mounts and the throttle body gasket sense you had both off.

Before you do that, check which thermostat it has in it, if it has one that is letting it get too warm or not completely up to temp when the computer think it should be, it would cause this. My 2000 crown vic did the same thing and thats what it was.

1997 opel corsa 14i while drive if I depress accelerator car backfires,how do I fix that

Tune it up. New spark plugs if they are over 50,000 miles old.

Backfiring is typically a symptom that occurs with a gasoline engine that has spark plug wires crossed, spark cross firing inside the distributor cap in dust or condensation or an over lean condition.

If it runs smoothly when normal cruise it wouldn't be crossed wires so that leaves an over lean condition or cross firing in the distributor cap as the most likely causes. So check the inside of the distributor cap for moisture, dust etc and clean it if you find it.

Next, to check for over lean on acceleration the most likely is partially plugged fuel filter so renew it. Next step is to clean the fuel injector (s) with the good breed of fuel injector cleaner that you add to the fuel.

I have changed ditributor cap spark plugs for my mazda626 92,v36,2.5. after i started its misfiring and i think its not burning the fuel,can see smoke coming from the i try to rev up the rpm...

Make sure the spark plugs are properly gapped (this will cause misfires). Replace all spark plugs wires!! Insure there is no oil inside the spark plug chamber.
