first things first: check to make sure your wires have a good TIGHT connection

Try swapping coil packs and see if the misfire follows it. smile

We've talked. He has some things he is going to mess with I suggested, I know about some of his issues more than he has described to yall. Hopefully he tends to those asap.

what other issues you got? Im interested in all the troubleshooting/diagnosing yall come up with. Gives me more "tools" for my "toolbox".

Well he only changed front spark plugs. Hasn't done the rear. Misfiring on cyl 6. Has had the car since like July of 07, no maintenance. Hasn't inspected fuel filter, who knows if that was ever changed.
Needs to do a tune up basically.

ahhhh. ok. I thought "other issues" meant that his car spit out the PCV or his ALT burned up or something.

Just the basics. got it. thanks.

Cat would do it! Do the tune up anyways!

My car was throwing that code around 7months ago...I did change my wires, and went away. But I've noticed for awhile if I give my car too much gas...it seems like something is holding it back....I might have to get the cat checked..

Re: p0306 - 03/10/08 06:34 PM

Might, I would get it checked out GTPJesse.
I did mention something to 01gt about his Cat, but I figured he had plugs and fueling issues to deal with first.

If all they did is a diagnostic check (OBDII) they lied about diagnosis and were guessing. A cat will never show up in the computer and the only way to check it is to check exhaust pressure through the O2 sensor bung before the cat.

Anyway, $200 max for a stock cat and installation. $700 is pure ripoff. Don't go back to that shop for future diagnosis or anything, they're just after money.
