I got the po301 code last week, replaced a coil and now the codes back and its sputtering, a different kind of sputtering but still sputtering when i first start it, is it the spark plug? do you think its fouled or??? it clears up in a few minutes or if u drive it once it gets past 3k rpm

 

Pull the connector to the injector while its running, see if it makes it any worse. Same with the coil just for fun. Look for either one to not make a difference when unplugged.

 

good idea.....I'll try that, but it goes away pretty quick, and it doesnt do it everytime...should be cute seeing me mad dash for the hood latch in the parking lot hahaha.

 

wow...the plug was finger tight, I spun it out just by turning the extension with my fingers...that coulda blown out. I'm going to change the other 7, the gap on it was a lil over 80 thousandths and I put the new one at 54, which was reccomended is that what everyone runs? trucks got alot better power now, must of been junk for awhile, original motorcraft plugs with 151k miles...

 

54 sounds right, I think thats what I set mine to when I changed mine.

 

is there a how to on the plugs? do u have to remove certain things or? I dont want to go and take everything off for no reason. I recall hearing the fuel rail has to go but I did the #1 coil and plug with it on there no problem??

 

When I replaced mine I had to unseat the fuel rail. If I remember correctly it helps with the ones closer to the back. I also removed the throttle cover and something else but I cant remember what it was exactly.

 

My throttle cover's been gone, I lost the bolts, haha...Ive only got 1...I have to get some someday. I actually like it better off, more access, it seems as I'm always fixing this thing.

 

If you want to drive to rochester I'll give ya a hand.

But honestly just remove only what you need as you go along so you don't have to start ripping everything out. It's nothing hard, it took me like 1.5 hours to remove the old plugs and cops and put new plugs and cops in my first time.

 

haha thanks...that isnt that far from here really, my buddys girlfriend lives there, hes always visiting. I'll have to do them, for some reason I thought they were a wicked PITA job?

 

No not all if you take your time. Also you might want to order a whole set of cops from ebay. Only like $80 if I remember. I had a wicked misfire, replaced the bad cop, went away, and then came back in another cylinder. Might as well replace all of them at once while you are changing plugs. Once one goes they all start failing one after another.

 

alright...I'll have to do that at some point.. I really don't want to though hahah
