Well to start off today i had a Flashing CEL today and i stopped my car and shut it down.About a minute later i start it up again and the CEL stays on.On my way home i hear a loud rattling noise which came from underneath the car and im really freaking out now.When i got home me and friend checked the rattling noise and it so happens my bolts that hold my rim where all loose?Im like WTF thank god it never flew off the highway?
The bolts were literly loose and you can unscrew them with your hands,so i tightned thge bolts up and that answered one of my problems.

Now my friend had an OBD 2 scanner and when i scanned the car i had 4 CODES!!!

P0300-Which is Random misfire detected
P0302-Misfire in Cylinder 2
P0304-Misfire in Cylinder 4
P51586-MT/AT encoding signal problem

So i pull out all 4 spark plugs and replaced them with new ones.I then took the car for a drive for about 1 hour and then when i rescanned the car there was no codes EXCEPT the P1586!!

Now my question is what exactly does this code mean?
I think it has something to do when i cut the PIN72 Wire which removed my CEL!!

 

Sorry my bad the code is P1586-MT/AT encoding signal problem!!
The thing is while im driving in first gear and as im about to release the gas pedal the car starts jerking and noticed the Rpms drop from 2000RPM to 1500RPM then spikes down to 800RPM.
ANYBODY HAVE ANY IDEA?????????????? sad.gif sad.gif frown
