i have had a K&N filter in my air box sense about a month after i bought the truck, so that would be january of 04, never any spark knock, never any check engine light with lean codes either!

i just got around to cleaning it for the first time this spring, the truck had just shy of 50k on it, i cleaned it and oiled it to K&N's specs, still zero problems.

see what i think is funny is that the factory ford air filters come OILED, both my truck and my freestyle and the 500 i had all had oil impregnated air filters installed from the factory, why ford does this i do not know.

I put a K&N filter in my truck 30 minutes after leaving the dealer lot, been running one ever sense in some form, 108,5xx miles this morning no issues.

Agree with the 2 above me. I've had my K&N for 7 years now and not one problem with it. I clean mine about once or twice a year.

Carbon buildup does two things.
1. Increases compression.
2. But most likely that's not the problem. Rather the carbon build up on the valves is making the fuel puddle on it and then get swept into the chamber in globs. That makes for inconsistant a/f pockets in the chamber. The burn is not propigated evenly and sometimes the burn starts in multiple areas too.

Clean the carbon off the valves and this will most likely go away.


Bob, I've beat my head against a wall enough with you. You have some knowledge.. but your simplistic views and LEAPS to grand conclusions are beyond my ability to reason with.

Here we go again Rich, your dead wrong about a dirty MAF sensor NOT causing pinging, and you won't admit your wrong! Very pathetic!!!

pathetic? no, correct, yes

"pinging" or spark knock is caused from carbon build up on the tops of the pistons and the back side of the intake valve. the fuel hits the carbon and becomes un vaporised causing a incomplete burn, thus pre-detonation, or spark knock.

the PCM does not know if there is excessive carbon build up on the pistons and valves, so fuel trim is unaffected. the o2 sensors control most of the fuel trim not the MAF. even if there was dirt or oil on the MAF the PCM should try to correct trim, in some cases it can not, in these cases a misfire or hesitation will result.

i am tired of beating my head against a wall also.

Mark, for your benefit, I'm re-posting the links I posted in post #14.

Obviously, you missed them, like Rich did!!!!

I hope you comprehended this information, and now know a dirty MAF sensor WILL cause pinging (or pre-ignition).

You guys just stop debating and give the guy some things he can check for problems. No need to go on with this crap it isnt helping anyone, and is cluttering up this thread.

Takeda you say its pathetic that wydopnthrtl wont admit he is wrong, well I think its pathetic that you end up getting into a fight or debate in every other thread you post in. You need to learn to ignore what others say, just tell the original poster what you think the problem could be and leave it at that. If someone says your wrong then ignore it. You already told the op what you thought it was and he has the choice to check or do what you said even if others say your wrong.

Also nice pictures in your sig.
