Hi all,

I just had my 1995 Z28 worked on a bit and when I got it back, while
it runs really nice, it runs a lot hotter than before.  I am wondering
what I could have had done that would have made the difference as well
as if it is a real problem and whether or not I ought to take it back
for a look-see.

It's a stock Z28 with nothing done to it by me except for a clean K&N
air filter.  The mods I had done were as follows:

Eibach drop srpings (1.3") (didn't lower it as much as I would have
expected)
Eibach anti-roll kit
Powerslot rotors/Hawk HPS pads (front and back)
KYB gas struts in front and KYB Gas-a-just shocks in back
Magnaflow cat back w/muffler
BBK 52mm throttle body installed
New AC Delco platinum plugs, wires, some hoses replaced and a new
thermostat
BF Goodrich 27540ZR17 KDWS tires

It rides smooth except over the hardest bumps and handles very well
with minimal dive during braking and it remains very flat in the
corners.  The BFGs replace the Firestone Firehawk SZ50s which they
don't make anymore.  The suspension results are what I wanted and so
far, the tires are performing well.

The problem with the hot engine though confuses me a bit.  While
running on the freeway, the needle always remained below the first
mark.  now it's above the first mark, halfway to the second mark.
Around town, the needle never got above the second mark unless I was
caught in really bad traffic but now it's up to the THIRD mark.  Also,
the tach is showing idle at 1000 instead of 800.  At speed, the tach
seems to be at the right numbers (1500 at 65mph).

The only thing I can think of other than maybe a botched radiator
servicing is that the new throttle body and exhaust are not working
right or maybe the throttle position sensor is out of adjustment.
Also, the plugs may not be gapped right.  Perhaps the shop just messed
something up and it's not something obvious.

I suppose I will have to bring it back and at least ask but I wanted
to know if anyone here had an idea of what might be wrong.

Thanks for the help!

P.S.  This work (including a full clutch job) ran $5600 and I decided
to do it to a 10 year old car with 94,000 miles because I can't really
afford a new car (busy paying for a house), a used SS would also run
me too much and this Z28 is still in great shape and I am very used to
it.  Might as well keep it at least another 5-10 years if it lasts.
