Ford f150 with a miss

bwelch · 08-20-2011, 11:34 AM

Its an 04 f150 v8 4x4. It has a sputter so my sister took it by autozone and it had almost 10 codes. The mass air, cam sensor, and crank sensor are the major ones. I'm leaning towards a cam sensor. What do the ford guru's think?

Has there been any work done to the truck lately, especially exhaust?

bwelch · 08-20-2011, 11:43 AM

Nothin. It was running fine till this morning. It was low on gas and started missing after she filled up. The gas cap is tight. I haven't went and looked at it in person but it sound like something with the cam sensor or phaser.

Water in the gas?

BigdaddyDupree · 08-20-2011, 12:52 PM

sounds like bad gas.

bwelch · 08-20-2011, 03:38 PM

I just talked to her and it started missing before she got gas. Thats what made her stop and get gas cause it was low on gas. I looked at all the codes that came up. 5,6,7,8 have a misfire. a misfire code for random cyclinders. It has a p0022 code for bank two. Isnt 5,6,7,8 bank two? Which makes me lean towards the cam sensor or maybe a phaser. What does the phaser do? never heard of one

chrisheltra · 08-20-2011, 03:57 PM

Can you list all the codes?

When was the last time a good tune up was performed?

bwelch · 08-20-2011, 04:07 PM

I have pretty much figured out it is the VCT/phaser. I search a couple f150 forums and have seen similar problems and codes that we have and they all replaced the vct. Its a dealer item! F'n BS. What side is bank 2? passenger or driver?

clubracergt1 · 08-20-2011, 04:21 PM

Very possibly a phaser issue. Used to see it a bunch at Jones.

bank 2 is passenger

Without having one in front of me to look at, I do believe most Fords have Bank 1 on the passenger side. This is opposite of the GM engines.

When in doubt, look to see which cylinder bank is more forward of the other bank. The bank that is more forward than the other one will be bank 1, with cylinder 1 being the most forward one on that bank. The only other variable between makes is how cylinders are numbered. Chevy and Dodge go odd numbers down bank 1 and even numbers down bank 2. Ford goes 1-2-3-4 down bank 1 and 5-6-7-8 down bank 2.

For something even more hair pulling, I once had a misfire code on a Dodge 3.5 V-6 for cylinder 5. No matter what I did to cylinder 5, I couldn't get the miss to move. What it ended up being was the computer was flagging the 5th cylinder in the firing order instead of the actual cylinder #5. Kind of makes you want to go strangle the engineer at Dodge HQ that used that kind of twisted logic when programming the PCM.

Which brand oil filter is on the engine? Some of the cheaper brands have been known to let loose a piece of filter media which usually gets stopped at one of the cam journals up in the head and starving that head for oil. 3 valve Ford heads have very small oil passages and it doesn't take much to restrict/stop one up to where there isn't enough oil to operate the phaser, much less lubricate all the cam journals. If you pull the valve cover and cam, you can inspect the journals. If they aren't galled, you can probably get away with just replacing the phaser or its actuator.

bank 1 is passenger and bank 2 is driver

I had like 8 code's and a P1000 I took it to Jones ford Refashed the computer and wala no more code's All the code's were a product of the computer reflash, ( Note Tommy's GMC had 70 code's a reflash of the computer cleared all of them)My 2 cents Lurch!

It ended up being the driver side VCT solenoid. Just got done fixing it.
