    You have no codes. 7.0 means that it is ready to go to the next mode.

    The diagnostic system on these cars has amazing capability if you know how to use it ( i don't!!) Every switch can be checked etc. I've been into it a few times, but didn't pursue it beyond what I wanted to know to fix something.
    Like if it ain't broke, don't mess with it

    I wouldn't worry about it. These things DO do a lot as said already. And its always chance they may act up with age. If you feel its running well and nothing to worry on. I wouldnt freak. Unless codes consistently show for something specific, see how it goes.

    Re: getting wierd OBD I codes what is it bad computer?

    ok thanks i know when 7.0 comes up it means no codes it always used to do that but never with an e7.0 thats something new thats why I asked it's hesitating but thats probably because it doesn't have ac delcos and 2 different sets of wires that stupid aamco did when i specifically told them to change all the spark plugs and wires with ac delcos

    I couldn't tell ya on that aamco stuff. I am just always sure when I replace, its the closest or exactly, to the originals.

    Not likely any problem with plug wires. Kinda sounds like a fuel problem, or maybe EGR operation. The book mentions the Cat converter too. I would think the EGR would show a trouble code though.
    I don't remember all the things you fixed so far. Fuel filter?
    Bad/ intermittent grounds are also mentioned.

    Have you checked fuel pressure? Also an injector stuck open will cause those symptoms too.
