I just had that problem and took in to the shop. Had the spark plugs changed and had a bad wire. Because of this I also ended with carbon build on the cylinder which they cleaned and had to have my fuel injectors cleaned because we had used fuel injector cleaner thinking that was the problem but caused another problem of gunked up injectors.

SOURCE: engine misfires

You didnt mention having changed the spark plug wires, so that is another item that could be culprit as well. As well, it could be a coil pack that is not working properly.

I cannot recall at the moment if that model year uses coil on plugs or if it uses coil packs. Either way, if it uses a coil on plug set up, take the one for the #3 cylinder and move it to say #4 or anyone of your choice and see if the misfire follows

If it uses coil packs, there is likely one coil pack that controls two cylinders. In that case just swap the coil pack with an adjacent one and see if the problem follows. Pay attention to where the spark plug wires go because it will be an issue if you get them mixed up. You just swap the coil packs around.

I would, however, start with the spark plug wires if you have not changed them already.

SOURCE: p401 emission code ford escape 2001 6cyl

P0401 shows an Exhaust Gas Recirculation Flow Insufficient. Without a good scan-tool you will be playing the "Parts Changing Game". Insufficient flow can be the result of a vacuum leak, bad MAP sensor, an exhaust leak, faulty EBP sensor, carbon build-up, and so on. I wish I could say more but with all the electronics it is more complicated then earlier cars.

P0304 is engine misfire #4 cylinder Several things can cause a misfire #1 electrical which you have covered #2 Mechanical Test engine compression is should be around 150 cranking and 120 running . internal valve train components can cause bad compression and the valves then self. #3 fuel injector can be the cause suggest swapping with a know good cylinder and see if misfire follows injector.

The flashing light means the problem is serious enough to damage the catalytic converter.
The code means cylinder 1 is not producing power. So it could be fuel, compression, or ignition related.

P301 and P303 Code with flashing CK Engine light.


Here is a pic of the regulator

The EGR valve is under the throttle body. You could take the vacuum line off the valve and plug it just to leave the EGR valve closed. Then drive to see if you still have the problem. I don't remember where the purge valve is, but it is usually in the engine compartment at the other end of a hose that connects to the intake manifold. The other hose goes to the vapor canister. You can pull the purge line off the manifold and plug both to keep the purge vapors out. If you spot any bad hoses in the process of doing all these things, that may well be your problem.

Have a p301, p305 codes (misfires) and p401, Engine runs really rough. 120000 and never changed spark plugs. Could a simple tune up fix this. Also replaced the egr back pressure sensor. What else could...


It is most likely an ignition system problem so starting by replacing the spark plugs and wires ia advisable.

If the problem persists then have the ignition module, and coil packs tested.

P301 Code on 2001 Ford Taurus SOHC (not FFL) with 253K miles. Replaced plugs and wires with Bosch Platinum +4 plugs and Motorcraft wire set. P301 returned almost immediately. Engine performance extremely...


Coil pack should in the front top of motor, with engine running remove one spark plug wire at a time from coil pack ( careful not to get shock ) they should all have spark, if one don't replace coil pack.
