    a bud of mine had an lt1 with the same problem, he got some intake cleaner and it worked. Just disconnect your intake down to the throttle body and fire up your beast. Spray the cleaner into it and rev the car up. Use the whole can, and get ready for tons of black shit to spray out the back. GL

    sounds like typical hi side electrical in the opti going bad. compare the resistances and voltages at the opti with what GM specifies.

    also, ignore eautocad.

    lol....

    my lt1 was giving problems similiar to that... it ended up being the sock (filter) on the internal fuel pump.... I would go through everything else that they say *first* like opti, because my fuel pump was not easy to get to.. and no fun at all...

    my car got so bad after running for a little while it would start to break up even at idle.. if yours isnt doing that and only breaking up when reving it probably is opti...

    quick test, wait till night fall, the dead of night when its really dark. open your hood start your car....... make sure you are not in enclosed garage.. look at all your spark plug wires and see if they are arcing anywhere. raise the rpms up to the level the car stutters, and see if you can see any arcing. The wires should not be sparking or showing any glow whatsoever. Its a quick test and you dont even have to get your hands dirty

    We can always choose to percieve things in life differently. It's important to focus more on what's right in life.. versus what is wrong.

    Yea I acually found out I have no money, and im hesitant to tear it down myself becuase it is by far the nicest thing ive ever had. Im 90% the problem is in the opti, it basically runs like a vehicle with piss poor timing.

    lol I know there not much, but my funds are real low. As of tonight my car lags when you rev it up fast and i hear a sucking sound once its warmed up which seems odd. I'm basically waiting to sell somthing so ill have some money.
