How-To: Eliminate 4.0 SOHC 'jolt/buck' symptons
Okay guys. I solved my 'jolting' problem at cruising speeds.
It seems that my K&N OEM replacement filter was indeed sucking up oils from the filter media and contaminating my MAF sensor. The cure was simple enough. Clean the MAF sensor and install a dry paper filter.
Here is a pictorial How To.
Tools recommended:
Gloves - recommended for dirty engine bays like mine
Flathead screwdriver - Optional, to help with removal of MAF plug
Zip Ties - To reseal air box if the clips are broken, such as mine
Cloth - To wipe down air box and MAF
Electrical contact cleaner: To clean MAF sensor
Difficulty: 0.5 out of 5
Time: Less than 10 minutes
Step 1:
Begin by unplugging the MAF connection by pushing down on the clip with your finger or a flathead screwdriver.
Step 2:
With the air box opened,remove the problem causing oil-based media air filter, by lifting it out of the bottom half of the air box.
Step 3:
Show anger at cause of problem by making a fist and then raising your middle finger, making sure it is pointed at the subject.
Step 4:
Remove new dry paper filter from box.
Step 5:
Install new dry paper filter with the mesh side facing up and replace top half of air box.
Step 6:
Make sure the air box is sealed tight as not to let in excess air which may also result in the continuation of the jolting symptons.
Step 7:
Go for a test drive and cruise at 40-60mph and make sure symptons do not return.
Step 8:
Problem solved!
*Disclaimer* This is actually not a 100% serious how to. Actually more of a parody. However, this did solve my problem and the photographs are more for humour value. Please take this into consideration before commenting. *

Well if I had a filter I didn't have to oil in the first place,then there never would have been a problem. However, this is about the 10th vehicle I've used a K&N filter in and the first one I've had a problem with.
However, not having to replace plugs,wires or resetting or reprogramming the PCM or doing anything else really made it a simple fix. This K&N filter is 6 years old and has over 190k miles on it. Probably about the 4th time it's been cleaned and oiled, and November was the last time it was done.

My jolting was a cruzing speeds, as you know since we talked about it. Just put in a factory filter intoday hopefully that'll fix it. When it gets about 20's im gonna clean the mass with CRC mas cleaner but i noticed my intake tube was dirty so might was that down also and check if my TB is dirty.

Very broken. Got that in October. Gravel truck on the highway at 70mph. Stone hit the very edge of the windshield right at the piller and put a big golf ball sized crack in it and it took 2 months to spread all the way across the centre of the windshield. I'm waiting til the spring to replace it, because by then I will need to do an Out of Province inspection on my truck in Alberta when I register it there.

That filter has been in the truck for 6 years with no problems until 4 days ago.
I had cleaned out the MAF prior to my little photoshoot. I wiped it out because the MAF tube was full of slime and crap.
Mark, as for inspection, my truck does not need an inspection unless I continue living in Ontario and change the ownership from my dad's name to my own. If that's the case,then I need to do safety and emissions inspection. Since I am moving out of province, I have 3 months to register the truck in Alberta,so before I move I am going to have my dad write me a bill of sale with no date,so that when I go to register it in Alberta, I change owners there and then do an out of province inspection and get it plated and registered under my name.
