3.8 v6 with 120,000 miles 1st week. Van started and began to cut out til I got it going on the road...check engine light comes on. Mechanic tested (code P0301) cyl 1 misfiring. He did a tune up with new spark plugs & wires and pcv valve. Seems to clear up. 2nd week. Van starts and begins to cut out again til it gets going on the road...check engine light comes on. Mechanic tested-same code. replaced coil hoping that was the cause. Started to cut out again and light comes back on. 3rd week. ditto. Mechanic disables fuel system and cleans with fuel rail cleaner? 4th week. guess what. cuttin out again and light is on....arghhhhhh I like my mechanic, but now he thinks I have the hots for him.....

Start the car with the hood open. Check the engine compartment as well as the fuel line from the fuel tank to the engine compartment. If there is a leak you will find it. Remember gasoline will evaporate quickly when there is air movement so watch carefully to make sure you don't look over the leak.
Sorry!,..More than likely the front seal of the transmission has actually cut a groove into the torque convertor neck.I have seen these hundreds of times, when the van is hot the seal wont hold the fluid pressure behind it and trans fluid will leak past...also the lines/hoses are on the side of this transmission..the vent is located on top of this trans near the main connector,.not in the front(Ax4n).,, seriously go to an accredited trans shop only for this repairATRA......again sorry for the bad new..Bob Stinson
remove the coil pack and look at bottom of it if it shows any cracks coil is bad very common on these vans if you have a noid light check for injector pulse on #4 if you have pulse and good blue spark most likely the injector is bad you have to remove upper plenum to get injectors out let me know how you make out
the check engine ligth just means you are not passing emissions right now. Coud be due to loose fill cap at some time, or filling the tank with the key on.
Try disconnecting the battery ground cable for an hour. Then reconnect and drive for 10 miles until computer relearns engine changes. It may run rough for 10 miles.
If still on, go to Autozone and ask them to perform a free computer scan & get the fault code. It will tell you which sysem to check.
Not given much to go on but first thing to check is the air filter , don't know your abilities but filter is in black plastic canister just to the driver's side of center under hood has black flip lever clamp in center and I usually have to loosen a hose clamp to get apart. depending where you drive this could get clogged in as little as 30,000 miles. the hoses connecting it to engine are about 3" in diameter. The filter is cone shaped and collects dirt on the inside.
