ohhh......more probs.....i think it's fuel system related....

[eseo@thecanyons.com (Erik Seo - The Canyons Resort)]

Heh, it fired up first time perfect this morning.....still seemed to lack a
bit of power though...

But thanks very much for the helpful advice.  I was waiting for a new idle
screw to come in, so that will be taken care of.  I'll check out the cold
start valve, i've been meaning to check it's operation, but have been too
lazy to look at it.  As far as the air/fuel ratio, I'll see if my local shop
can squeeze me in this evening....hopefully they'll get me in, and let me
see what they're doing so i'll know how to deal with it if it happens again.
i was hoping to get the rocco into it's second autocross this
sunday....hopefully it will be happy and i can!

You need to replace the o-ring on the idle screw and IF you had bad injector
o-rings then you should have the air/fuel ratio set (or set it yourself if
you know how).  You set this adjusting the plunger in the fuel distributor
with a 3mm T handle allen in the little hole next to the boot.  IF you have
no idea how to do this then take it somewhere where they will charge $30 or
so to do it with a gas analyzer.  Too rich and too lean can be bad and
sometimes can only be a smidgen of a turn in either direction.  Idle is also
valuable during the setting of the air/fuel ratio and sometimes timing can
come into play when the idle is set really high to offset the bad air/fuel
mixture setting.

Seen it, done it, glad I don't have to do it everyday for a job anymore!!!
Actually it is rather entertaining to see how much of a hassle some people
cause themselves when the pittle around with their car and they have no idea
what they are doing.  I usually played the good cop though and set things
for them and sent them on their marry way with money still in their pocket.

HTH!!
