Keep getting p0302 code

Ill be honest. I did run a couple tanks of pure e85 in the car over the summer. Now i got issues when cold. That may have been a cause. As e85 dont like cold and gels up and probly busts them jecters. I did read before that the 15 MY sho can handle it because pump is suppose to be better. Either way i made it home. Dead miss at any rpm but 2k. Runs good at 2k and cel light goes out but as soon as its under or over its flashing cel light. I guess the jecter only runs good flow for 2k rpm no more no less, just my 8 cents.
Fun fact, you know that usa had in circulation a 3cent nickel at one time

Yeah rail pressure/volume become a big problem with any kind of spirited driving. I think max run successfully was E45 on the stock fuel system. E85 is way way beyond that.

3 cent nickel huh? Plugged or unplugged? J/K. Will have to look it up.

 

[yaycandy]

The jecter is coming in the mail tomorrow. Motorcraft oem. Hopefully it has the teflon seals with it. Ill get it tore apart either tonite or tomorrow morning. Dont look to bad. So i hope it goes well because ill have 5+ more thatll go bad haha

Best to plan for all 6. I know now gdi injector cleaning services are available but no idea how effective they are. If you have a setup to clean common rail injectors, you can do these as well.

 

[yaycandy]

Common rail? Im a holley 850 double pumper kind of railman. V6 aint to much of a common rail if.......theres....2....right. Common on the back half but uncommon to front half type of common?

 

[yaycandy]

Oh i see how it works now. 1 spits to 2. I think i had to many drinks already. But i brought out my old lady mobile. A i built 507ci bigblock with 600hp and 890ftlb on an engine stand dyno. All that tork going through a rebuilt turbo400. Front left yanks up good

Common on the back half but uncommon to front half type of common?

yes. that type of common is very common

 

[SHOdded]

Common rail as in diesel engines LOL. Really the forerunner of modern GDI technology.

They all that bad. Seafoam will fix it i hope

Why does the cylinder that miss fires jecter look new compared to the others?

 

[yaycandy]

Cylinder 2 is the middle rear aint it?

 

[Johnbigdog]

From the transmission looking to the acessory drive bank 1 is on the right. Starting from the front (the acessory drive) is 1,2,3. Number three being closest to you. You are correct.

The valves look normal for gdi engine. There is nothing to keep an clean.

 

[yaycandy]

The injector that has misfire is clean and others are normal carbon coated? Whys that? Sticking jecter?

 

[yaycandy]

New injector in. Still runs the same. All misfirery. No codes yet. Probly will show the same. I guess ill have ford look at it. I did a compression test also and got the same numbers across all cylinders. Pretty close to the same

 

[yaycandy]

Maybe spark plug wire is bad

 

[yaycandy]

Yep codes just came up. 302 and 316. 316 is misfire at startup and 302 is cylinder 2 misfire

 

[Johnbigdog]

Maybe spark plug wire is bad

You already swapped coils and plugs right? Not these then.

Youre down to a circuit, or a valve train fault.
