Hi, /o/. I have a problem. Recently my car has developed a misfire.

Change plugs and go from there

>>16152855
I did the plugs today. (Probably should have mentioned that) also the plug boots don't have any signs of cracking, rotting, burning, or anything. Same with the wires. Although, I think the wires are still stock.

>>16152871
Swap the wire with one from a different cylinder. (both end) if the misfire doesn't jump to that cylinder it could be the fuel injector. If it was both banks it might be a clogged fuel filter. It could be an air leak after the maf sensor or vacuum leak somewhere.

I had an issue with persistent misfires that would start when the car hit operating temperature and it ended up being a valve issue.

>valve issue

Pls no

>>16152871
I change wires with every plug change. To eliminate the mystery.

>mfw I also have a 4.6 that just started having these exact same issues (shuddering and missing without any visible fluid/exhaust issues) and the same code (cyl 8 misfire)
Let us pray together.

Just doing a little googling it seems like this is a fairly common problem for the 4.6 so you're probably not SOL quite yet. You know what they say Ford stands for don't ya. It stands for fix it again tony.

Change in fuel?

Had a similar problem when I was forced to use 89 octane in an 87 octane engine. Missing due to timing issues with higher octane fuel. Only ever happened at operating temp, and had loss of power associated with it. Once tank was driven empty and filled on proper fuel, it resolved.

>>16153093
Well that day it started I did get a full tank of gas. And it was in NJ where you can't pump it yourself. If it was bad gas wouldn't it be misfiring on more than one cylinder?

>>16153142
Don't know, but it will cause weird engine issues. Mine just kind of intermittently missed. I was like 16 or 17 at the time, so I don't remember well.

You can always drain the tank and get a fresh fill and see if that fixes it. Problem solved.

>>16153142
Also, not being able to pump your own is fucking retarded. Wife and I drove through Oregon, it's weird.

irrelevant to current post but i need help. i didnt want to open a new thread for my question

So i was changing the hose for the radiator because it broke and i well i replace it and placed things back together. but there was one hose that i couldn't recall where it went. can you guys help me out. i have a 1996 nissan altima.

thanks for the help, i really appreciate it

>>16153424

Trans breather hose, I believe. That is where it goes.

>Watch for gushing water.
>Attach hose to whatever water came out of.

>>16153071
my nigga.

>>16153488
yeah i think that's what it is because it was close to the air filter when it was moved. i am concerned that it has to be connected but my friend did say it wasnt connected when i was working on it.

>>16153494
it was close to the air filter thing. i had to remove that section to get to the hose that i needed to replace

thanks fellas. but if anyone thinks otherwise i'd appreciate the info.

How many miles?

Check any rubber elbows on the pcv system under the hood. The heat causes them to soften up and they suck themselves closed or develop a leak and pop a lean code. Since both codes pertain to bank 2, I'd look around that side of the engine for any rotten hoses.

I'm not sure. The odometer is broken. Maybe 120k+.

There is carbon blocking one of the intake valves. Easiest fix is to.go to the to of a steep hill. Go about 20mph turn the engine off, then turn key back to the click before the starter motor. press the accelerator fully down to the floor stick the car in second and drop the clutch.

This will blow out all the gunk with a bang!

Be aware when the car is off you lose power assisted steering and brakes so dont do it when other people are around

OP here

I have found the problem. I swapped the #8 injector with #5 and the misfire has migrated with the injector.
