[Shotimes] Aggrevating Engine Problem, Part II

[Thesing, Hunter M.]

Hey, all, its me again.  My problem is a bouncing idle, and now I've noticed
that it doesn't want to get up and go at times.  For the idle I was told to
check for a vacuum leak.  I checked a few hoses, but nothing yet.  My IAC
valve is less than a year old and doesn't seem to be the problem.  As for
the lack of power, it feels as if it's not getting enough fuel.  I've
experimented with it lately and found that when it doesn't want to go, I can
rev it up, dump the clutch, and she take off like a bat out of hell
(sometimes, otherwise it doesn't help).  I was also told to check the MAF,
but I don't see how this would help the lack of power.  Anyways, I haven't
checked it yet.

It seems as if it's trying to keep the idle steady, and sometimes it does.
But I really hate having to restart it every time I push the clutch in when
I am driving.  It's drivable, but it's getting to the point where I don't
want to deal with the headache anymore.

I ran the self-check on the computer and came up with the following codes:
114, 172, 173, 176, 542, 556 (KOEO).  Be aware that I just replaced the O2
sensors and fuel pump, and the IAC valve and fuel filter are fairly new.

Again, any help would be greatly appreciated.  Also, a tremendous thanks to
those who have already offered suggestions!!
