Default Same thing? Or separate problems?

For the most part my car runs pretty well. But almost every morning on the way to work if I run at lower RPMs in 6th (below 1500) up the hill I have to drive over it will miss. Usually it'll do fine if I go down a gear. And then there's the times when I try to aggressively insert myself into traffic and nail the throttle in 1st from a stop. Many times it'll just fall flat on its face. Fortunately I haven't caused any real problems when this has happened, except for maybe the cars behind me thinking they can go too and are surprised when I hardly move.

Any thoughts? Injectors? Vacuum leaks? ECM?

Thanks guys.

have you tried pulling diagnostic codes to narrow this down? I got the following link from bogus:

if you have not done this yet, I suggest it as a good next step

nw, just be a tad less quick to shift up to the next gear especially 6th gear. The first gear drop off doesn't sound normal. Something to be looked into.

Pardon my ignorance, but I am under the impression that codes are only posted when an error lite comes on the panel. There are no error lites. Does the control module talk even when its not turning on error lites?

I just ordered a Helms Manual and printed out the CCM Code Reading guide by C4 Guru. Thanks for pointing me in the right direction.
