LEFT side of engine, cat was glowing cherry. So that bank is running extremely lean. Also have p0305-p0306. So cylinders 5 and 6 are missing, feels like a dead miss, snapshot data tells me that, at 1500 and change RPM I have 34.6 psi. Is that too low? Shouldn't I already be up around 45. 30% on tps as well. Ive heard of bad fuel pump grounds and clogged fuel filters. I also had p0300. Not too familiar with Fords but dont they throw 300 for farting in the seat? My attempt at humorously saying they throw that code all the time. I have to say this truck is really turning me off to fords. Id sell it but its financed and any dealer is trying to take us to the bank. Please help

 

Which left, the driver's left or the left as seen while staring at the engine in a forlorn or puzzled manner?
No, it's running extremely rich due to the misfiring cylinders.

it would help if you explicitly identified your vehicle including year and engine. We aren't psychic.

It's been 7 years since mine threw ANY misfire code.

If you recently bought this truck, then the probability is high it needs routine maintenance. That isn't Ford's fault as maintenance is the responsibility of the owner(s), present and past.

 

Lol, I'm a mechanic so from drivers seat. 2007 f150 5.4L. You're absolutely right its running rich, I got it backwards. You are also right about it not being Ford's fault. When the truck is good, its SO GOOD😍😍😍. I guess I'm just butt hurt about the whole situation. That being said the plugs were changed. What would you recommend for coils? That seems like the place to start at this point. Thank you for setting me straight. I got this truck from an.......ahem idiot to put it VERY nicely😒. Is there anything else known for causing ignition issues? I guess I should change plugs again. Again any suggestions?
