    with engine idling, pull one spark plug wie at a time with plastic pliers. When you pull one and it makes no change in engine, that is a bad cylinder.

    Could be a burned valve too.

My 1999 ford escort lx is jolting when accelerating and when idling it feels like it wants to die but doesnt


Water in gas, plugged fuel injector, plugged fuel filter, bad plugs or wires. Its tune-up time! Start with the easy stuff and go from there. Hopefully it's an easy fix.
Could also be plugged catalytic convertercatalytic converter or bad torque converter

I have a 1996 crown vic i need to know these touble codes po305 po304


P0304 means that cylinder 4 has a misfire and P0305 is a cylinder 5 misfire. What this means is you may have bad spark plugs, or bad plug wires, or you may need to replace your distributor cap and rotor. I would start with plugs and wires.

Ses light flashing, truck running rough


Good Evening. I'm sorry to hear your truck is running bad, however I can give you a few points to check on. Your flashing SES light is because you have a misfire in your engine. The misfire could be caused from things like spark plugs and wires or a cap and rotor, low fuel pressure or bad gas. Or the other things like an intake leak or a bad valve so diagnosing is harder without the code that is set while your SES light is on. So get a scanner hooked up and see which cylinder it says is misfiring and go fron there back to the wire to the cap etc. Hope this helps and if you have any more questions please feel free to ask.

Took my car to have check engine light checked. It said misfire cylinder 2. I replaced the spark plug wires and spark plugs and it still says misfire cylinder 2. What is the next step? Thanks Steve


In modern cars so much can go wrong to indicate an issue and a computer in the car can get confused as to what is really occurring. In most cars a misfire indicates either an incorrect firing order, shorted wires, bad plugs, or bad coil. Since you have replaced the wires and plugs we can rule those out. Im also assuming after the second engine code you pulled #2 plug and made sure it wasnt fouled with oil, was gapped correctly, and reinserted. To produce a sufficient spark for combustion the alternator sends power to a "Coil" which is in reality a storage point that then sends an amplified electrical current down the spark plug wire to the cylinder to fire the plug. If the car is truly misfiring you will notice a rough idle, fluctuating RPM's, and lack of acceleration. If you are experiencing any of these I would look at replacing the coil. If you arent experiencing any of these I would have the code cleared again and complete one drive cycle 100 miles and then have codes read again. If you still get a Misfire error some other causes known to occur with Rio's are fuel filter issues, gas caps, and fuel injector issues. Although rare, these can cause issues with the cars fuel delivery and emissions which can confuse the sensor in the ECU. I would try injector cleaner, replace the fuel filter, and gas cap . If funds are an issue then based on symptoms I would start with injector cleaner first $3, Filter $12, Gas cap $12, Coil $48 to $200+

96 Ford Explorer is studdering (misfiring) when going up hills


I have the same exact problem that just started immediately AFTER I got a tranny service where they changed the Trans Fluid, Trans Filter, Fuel Filter. Took it back and they say nothing is wrong with it. Took it to the dealer thinking I could get some REAL answers... they just told me to replace spark plugs, wiring & coil, for $900. Only studders when quickly accelerating above 40mph. I've check other forums, they say to clean the Mass Air Flow sensor. Haven't tried it yet. This seems the easiest before replacing spark plugs. Any other suggestions anyone?? Please.....

Misfire on 3


Misfire on 3 could mean bad plug or bad wire...or the distributor cap has a bad spot in the 3 position. Time for a tuneup. Get all new cap, rotor, wires, and plugs. Should be around $100.
