How to check coil packs and spark plugs wire with a multimeter. ..having random/ multiple misfire P0300...need to know their spec? 97 Cadillac Deville, 4.6 engine/Northstar


I don't think you really understand what this fault code means, it means that likely all the engine cylinders are misfiring at random no set pattern, not any particular cylinder. I would start with checking for engine vacuum leaks like the intake manifold gasket. that is all I can say since you provided no make, model or year and engine type and size information.

The tok tok sound is probably a blown exhaust gasket. Replace the exhaust manifold gasket. As for the rough idle , replace the distributor cap, cap rotor, spark plugs and wires. With any luck this will take care of the misfire at idle and improve your gas mileage for a minimal cost for the repair.

Spray around the intake manifold with carb cleaner. If the engine smooths out or revs up, fix the leak. It sounds like a leaking intake manifold gasket.

hi is your car a fuel injection or carburettor model ?
it sounds like you may have an air leak somewhere around the inlet manifold
check all vacuum pipes and hoses for leaks when the engine is running your looking for any hissing noises ,use a length of rubber or plastic hose to your ear and probe around the engine bay with the other end like a stethascope it sounds silly but this is a very affective way of finding vacuum leaks

Cylinder #2 Misfire-after intake manifold replaced


It's possible he has two plug wires crossed, or pulled a spak plug wire apart replace #2 spark plug wire First. To test check the firing order and make sure all the wires on the right plugs and the correct place on the distributor, if it is right, then buy a can of carburator cleaner and spray around the intake gasket if the engine revs up when you spray the carb cleaner around the intake manifold with (engine running) if the engine rpm revs up you have an intake leak.

1991 Camry running rich


check for vacuum leaks especially around the intake manifold gasket. Although the engine appears to be running rich, it could also be misfiring due to being too lean in one cylinder. When the cylinder doesn't fire the charge, it goes into the exhaust completely unburned and looks like a rich running condition due to the unburned fuel. If it is a vacuum leak causing the problem, the engine will run fine at road speeds but misfire at idle and not pass smog.

Misfire


i would bring it down to the shop and have the timing checked and the timing belt or chain replaced....also check for vacuum leaks as this could be a problem..however you can usually check for bad vacuum leaks yourself by once you start teh vehicle pop the hood and listen for any loud hissing sounds.....also teh car wont start anymore? did you see that the fuel pump was operational? also id have the shop put it on the computer odbc and check if its throwing out any codes to tell you whats wrong with it.
