Most likely this is a false code being shown due to a faulty Map Sensor or O2 Sensor. Replace the O2 Sensor at the downstream position and double check any exposed wires for damage. I have had this problem in other vehicles, it turned out to be an exposed wire on the Downstream O2 sensor that was grounding causing a problem and a bad O2 Sensor. The MAP sensor will do the same thing on occasion but is less likely.

I have a 2000 Dodge Stratus with a random misfire on 1,3 and 5. The engine runs fine besides a twitch in the motor that can be felt while idling. Already replaced plugs and wires. Suggestions?


get the OBD codes read this will tell you which switch/sensor is causing the issue , the last random misfire i encountered turned out to be low cylinder compression so if the OBD code says " random misfire " then get the cylinder compressions read , hope this helps

Intake or vacum leak will be the first codes 174,171, try idle and spray propane around intake if car idles up, then intake is leaking, otherwise could be a broken vacum line, check with a gauge

Replaced upper intake gasket, still losing antifreeze this time not visible


Did you change the Plenium also / if not you should of, these also go bad and leak antifreeze through to egr port , most parts stores will recommend you change it too, i've done several and they look good but the plastic turns soft and leaks coolant to egr port.

My 2003 Tiburon GT is having random misfires on cylinders 2,4,and 6. I have replaced the plugs and wires and it drove fine for about an hour. Started misfiring again on the way home for about five minutes,...


Check you fuel pressure, If it's low, it cause cause your symptom. Have you checked your timing? Your belt may be skipping, if it's old it could be losing it's teeth, change it before it skips bad enough to cause you valves and pistons to crash into each other. Could be a bad cam / crank sensor also. Pull your codes and see what you OBD II is telling you.

Po300 random mulitple misfire detected p1399 misfire any cylinder


If only one of your cylinders was misfiring, you probably would be getting a more specific code than P1399.
Also check the distributor rotor along with the cap and coils and wires (as mrgreenz suggests); the EGR valve to make sure it doesn't leak; your fuel pressure which can cause random misfires if the pressure is too low; and injectors if they are really dirty. If you have really high mileage, I probably would first just change out the plug wires with a new set, then reset the DTC and see if the code comes back.
Hope this is helpful as well.

96 bmw 740il misfire


This is a pretty common problem. I would change your valve cover gaskets. They run around ~ 50 bucks. If they are bad it will leak oil into spark plug well and cause a misfire. Very known on the 740.. Also if tune was not anytime not too long ago id change spark plugs while you at it. Then clear the computer and if you still get misfire on 8 try changing the ignition coil which is right about the cylinder with cylinder ignition coil 5. clear the computer. if you get random misfire and misfire cyclinder 5 after then its your ignition coil. parts store runs around 100 bucks
