My '99 'burb is making a strange sound lately when you push on the brake
pedal.  It sounds like air is leaking from them, although that can't be
right.  Is there some sort of air-actuated control on them?  I checked the
resevoir and it is full, when I turn the truck off, the ...

I keep getting the check engine soon warning on my 94 Sonoma, 4x4, 4.3, 5sp.
It only comes on after about 30 to 40 minutes of driving.  The temp is good,
oil pressure is good, oil level seems fine but it's hard to tell exactly
because it splashed up the stick real bad.  When I ...

Vehicle is a '98 K2500 with 5.7L (350). I just finished up replacing the
intake manifold gasket. Upon initial startup, I get a loud metalic popping
sound. Almost like something was left in the vicinity of the belt. Not
rythmic, though. It was one of the first things I heard the ...

Had an odd thing happen today. Crusing along at 70mph and fuel tank is
close to empty but not quite, and suddenly I get a surge of power that
felt like a turbo kicking in (not a turbo vehicle), and it went up to
80mph without moving the pedal. Then as suddenly as it happened it

That empty bezel bugs me.  Is there  an aftermarket tach I can get to stick
in there?  I note that LMC truck's catalogue lists fuel gauge w/tach or w/o
tach, whatever that means.  The illustration just shows a fuel guage.  My
instrument cluster is the two big guages for fuel and ...

When I'm at a normal rpm for driving say 3rd gear ( manual 5 speed ) 30 mph
my truck will start to buck and jump till I give it gas. I have given it a
tune up tried fuel cleaners, I need help can't figure it out!

 Hey guys,
  I posted this same question over in the caddy section, you never know.
 Do the old cadillac engines(425,the other one,502)have the same bolt ups
as the old chevs?  I have a chev 350, and I want to bolt a 425 inch big

I have an '86 GMC Jimmy Runs great (It should, It's got lots of new
parts!) but A/C is a problem.  Operates/blows cold air for 20~30
minutes then A/C Fuse blows.  Compressor, drier, and orifice have been
replaced with new GM parts, new PAG oil and R134 refig by

Anyone out there seen this happen? 1 round rust spot (about 1" wide),
flaky brown, peeling by the third bake light?? I bought the truck used,
didn't notice the spot then.  It has 49K on it, warranty book says rust
warranty 6yr/100,000 but dealer says they can't do any thing!!?? This

I've seen X shaped hood braces on older cars, the welds on the hood of my 86
1/2 ton are all popped, and the hood is kind of floaty.   LMC Truck sells
some brackets, but they're just a couple of pieces of channel that run
partway down each side, nothing that goes across.  Do they ...

In a previous post, I detailed the problems I'm having with my '99
K3500.  Basically, it boils down to.....on a long trip I started having
performance issues (won't pull hills, very bad mileage).  Hooked it up
to a scanner and got a code of P0171 - Bank 1 Lean Fuel Trim.  Since

The  factory tape in  my  94   k1500 wont  work   so  i want  to  put
in a am/fm/cassette i  have.  I have   what  they  tell me  is  the
right  wiring  adapter.Do i  need  to   remove  the  underdash  part  of
the  radio  to get   to  the  wiring, as  the  adapter will  not plug in

Anyone know the fuel tank size for the 2500 Duramax?
