Help with codes

Started off, was driving fine and then shudder and noises and went to limp mode.


Had p305 and 306 codes, misfire in cylinders. Started with new plugs. Have same 305 and 306 codes but now threw a bunch more up. Not sure where to start now. Thanks for add and help.

 

Welcome to TW…

 

Ty. I've done search. Sort of overloaded and frustrated.

Here's a pic of

 

You swapped coils from known good cylinders to see if it moves with them?Is
#5 and #6 misfire on cold start?…loosing coolant?

 

Man, I’ve seen a jacked battery cause a code avalanche… I think it unlikely that 2 coils puked at once. Have you ever cleaned the MAF?

 

Nice looking truck btw.

 

I didnt , but when I changed plugs, I forgot to label which coil was from which cylinder. I kept track of sides, but not cylinder. 33% chance I got the original 5 and 6 back in their original cylinder. But ill tey that tomorrow and see if they move.

 

If you just randomly put the coils back, then I’d say the chances that you put 2 bad coils back on the same holes is slim.

 

Agree, having same cylinders throw code is frustrating me more. Im going to get a new battery tomorrow and start fishing lol

 

Also, 5 and 6 spark plugs were bad. They were all black and nasty.

 

More so than the others?

 

Yeah , by a long shot. They were all.black, the others weren't too bad

 

Sounds like you could be rich in those 2. Pretty soon the smart guys like @Dm93 or @TnShooter or @Jimmyh will be by to help.

 

How the hell did the ground strap get pushed down onto the electrode?
WTF???????????

 

I'd pull 5 and 6 and see if the new ones look like that.....
You got issues, a weird one at that....

That's doesn't just "happen".

 

Its Friday tomorrow

 

Either too long of reach plug or it was dropped/smashed prior to/during install.

 

Ill pull and see. We bought it used a year ago, that wasn't my doing lol.
