That'* a good question. There isn't a code 58 specified in techinfo. Hang around a bit...

Check again and see if there were any more codes after 58. Keep watching until you get 6 12'* in a row.

What was that? I got a red "x"....

EDIT: if you have a pic to post, send it to mypookiness AT hotmail DOT com, and I'll post it for you.

A blown plug tip? I hope the fragments didn't damage anything in the cylinder, like a valve for instance. You may have far more serious problems, especially if all your plugs were oil fouled.

When was the last time you replaced your PCV valve? Code 58 is a Vats (or Passkey) fault. Try another key if you have one, or clean the contacts on your resistor pellet AND the contacts in the ignition switch.

Are you getting a security light?

Judging by the damaged plug, I'd bet you killed an intake valve. It would explain the rest of your symptoms.

PCV valve is less than a week old, changed that when i changed all the rest of my stuff, if you mean security light as in the light flashing security yes i am, and all im getting is that code 58, if i did mess up a valve what am i gonna have to do to fix it, and why did it make one Huge puff of smoke if it was a valve??

Code 58 may be bull, as alot of 92'* have that problem for some reason.
Are you sure the PCV valve was installed correctly?

How could an intake valve cause that puff?

You've already stated your plugs are oil fouled. You have oil in your cylinders. The plug tip damages a valve, so that it can't fully close. As the cylinder comes up on compression stroke, the oil is pressed up into the lower intake.

Just a theory, but it makes alot of sense. To fix it (assuming I'm right) you better be very familiar with pushrod engines and buy a maintenance manual. Depending on the mileage of the motor, most people would replace the whole motor for something like this. There may be other hidden damage, like scored cylinder walls, etc.

umm 162k miles on it, and err would a complete engine rebuild fix it or is new engine pretty much my only option? i mean can i just get one from a junkyard or something and rebuild that one or just put it in?

Here'* the pic:

one more thing, something wierd happened,when running the codes, after it did its thing a bunch of times, just repeating 12 and 58 everything like turned on and my fans and everything were just going full speed, and the SES light was blinking very rapidly.
