ford five hundred code p0301

Post by k » Sat Jan 13, 2018 8:50 pm

My Ford 500 current mileage is 97500 miles. I have a engine light code p0301. My mechanic friend told me do not waste money to repair since there is also oil leak from engine.

I did replace spark plug and cost a lot of money over $300 but did not change spark plug wire since the poor mechanic shop did not change together. It really waste me $300 just did a month ago and also changing belt and transmission oil together. My Goodyear tires only run 8000 mileages.

My mechanic friend told me I could keep drive without burning catalytic converter.
The best way is wait for next year smog check and ask government buy it back for $1000. I probably have to wait for another year since I already pass smog check this year.

Is it true the catalytic converter of Ford difficult to fail if my annual mileage is less than 5000 mileage since this is v6 not 4cy car.

Did anyone repair code p0301?

Please let me know.

Thanks

Wow, your mechanic friend told you to not repair a misfire? That's terrible advice. That is such stupid advice when you live somewhere that does emissions testing, let alone California!

I don't know about the annal mileage part, but see https://www.obd-codes.com/p0301 for help on that code, and stop taking advice from your friend. Find a more qualified person ;-)

Well its a misfire on cylinder 1. Your 500 has Coil on Plug. You do not change the spark plug wires. You will have to remove the upper intake manifold to get to cylinder 1. It takes 20 - 30 minutes to take it off. You can then remove the COP from cylinder 1 and swap it for COP from cylinder 4 in the front of the engine. Then replace the upper intake manifold. If the misfire is then P0304 then you know that the COP boot or coil is bad. You can easily replace the COP on cylinder 4 without removing the upper intake manifold.

While you have the upper intake off you should replace the PCV valve and the egr o-ring. Personally I would also clean the fuel injectors in the upper intake manifold while you have it off. Replace the gaskets because they are very inexpensive and clean the throttle body while your in there. Since you already did the plugs i'd replace the boots for the COP and line them with dielectric grease so they wont arc. You might as well check the gap on the plugs and the condition of them.

Do not put dielectric grease on any metal contact points, just a small amount on the boot surface that will touch the porcelain of the plug. FYI the correct use instructions. Many (most?) people use it wrong. The word dielectric indicates why it doesn’t help electrical connections ;)
