Misfires on bank closest to firewall

[2013SHOpp]

I've been trying to figure this out and could use some help
. I'm getting codes 300 301 302 303 and misfire before 1000 rpm. I'm also getting a Code saying the camshaft on bank 2 is overadcanced but I've retimed this motor 3 times and get the same code. I'm thinking it may be the injectors or the clip that connects that bank of injectors. Anyone have any ideas?
I'm also getting a code for the cam sensor but I've switched them out with same result

I forgot to mention, I also get a very strong smell of gas. It's leaking from somewhere buy I can't see where or maby it's just unburnt gas from the misfires

Sounds like a stuck phaser or VCT. Pull the valve cover and rotate the engine so that the cam flats, that the cam tool locates on, are perpendicular to the head. Both cams should be the same. If not, the phaser is bad. If so, the VCT is probably stuck.

so that system has the cam gear part and the part that controls the oil. I'm assuming the cam gear us called the actuator and the other the solenoid. Is there a difference between left and right bank solenoids? I have a few different solenoid from different manufacturers and some are different at the bottom? Also, great idea, cam phasing never crossed my mind

You say you've retimed the motor 3 times. Did you have the front cover off? How many miles on the engine? Bank 2 is the front bank. Cam shaft sensor code for which bank? Did the problem start out of the blue or after some work was done on the engine?

 

[SHOdded]

did you replace the vct solenoids when you did the timing/wp job? is the system timed correctly now? are you on a stock tune or ...?

sometimes general misfires can end up being leaky valve cover gaskets or pcv valve related issues.

check the coil drivers in the pcm to make sure they are not burnt out.

 

[2013SHOpp]

I'll have to Google what coil drivers are. I did change the solenoids and the actuators when I did the timing. I'm 99 percent certain the timing is correct. I bought and used the tool that holds the cams where they need to be. Stock tune. Ijust put catless downpipes on it and the more I drive it the better it seems toget. Maby relearn process

This all started after I put it all back together after doing timing components. 016 came up so I re did the entire job and it came back again so re did it again. Yes the timing cover was off. The last Time I had the machine shop go through the heads for good measure and now it's only intermitten. The codes always show up together and they are 016, 300, 301,302 and 052 and also 011

Well, it all started after you did the work. P0011 and P0016 have the same possible causes. Both refer to Bank 1. Misfires are on Bank 1. If you are sure the timing is correct, I'd suspect an electrical problem. Maybe you forgot a connection.

• Camshaft timing incorrectly set
• Continuous oil flow to the VCT piston chamber
• Erratic camshaft position due to low oil pressure
• Oil flow restriction in the oil passages or the VCT valve body
• VCT solenoid stuck in position
• Open or short in the VCT circuit
• Open VPWR circuit
• Camshaft advance mechanism binding (VCT unit)
• Damaged VCT phaser
• Damaged camshaft position (CMP) sensor
• Open or short in the CMP sensor circuits
• Radio frequency interference

One other thought, you replaced the VCTs and phasers with new Ford parts? If not, that may be a problem.

 

[2013SHOpp]

So the last few times I cleared the codes the codes tht consistently return are 011 016 and 052b. The misfire codes have not showed back up after I cleaned the injector harness conector

I also need to look through all of the ground connections and make sure they are solid connections. I have been using Rockauto to get my parts most of the time. I never pick the cheapest part and also never the most expencive. If motorcraft parts are available ill get them, but if not its the ones that are the better part of middle of the road if that makes sence. At this point im leaning on it being an electricle issue. I have a few cam sensors that im going to switch out and see how that works out. I believe i just switched it out but i may have switched the wrong side
Also, am i confused thinking that bank 2 is the firewall side of the engine? And thank you for all of your help with this. i really appriciate all of your help with this

 

[SHOdded]

bank 1 = firewall side
bank 2 = radiator side

confusion arises because the terminology is rooted in longitudinal engines, where the belts and pulleys face the radiator. the bank on your left is bank 1, right bank 2.

so imagine turning the engine in the sho 90 degrees. and there it would be.

Correct in this instance. Bank 1 is not always on the left or rear. Bank 1 is the bank with cylinder 1.

For these types of parts you are taking chances with aftermarket. Ford or Motorcraft only. They may cost more but, you are far less likely to have problems. Please don't tell me you used Dorman.

I wouldn't use Dorman. I may not be the sharpest knife In the door and I definitely do stupid things but I'm not ********. That and I actually like my car

So at the end of the day it turned out to be a bad ground connection causing the codes to show up

 

[SHOdded]

glad the fix was simple even tho the path to it was not. did have a broken ground strap once on our 95 but thats about it.
