I've had my 96 K3500 with a 454 7.4L engine for a few months and ever
since the weather cooled down from the hot summer days it's hit or miss
everytime I try to start it.
Now when I try to start it, it starts up running very rough about 70%

I have a 98 S-10 blazer, 4x4 with a 4 speed automatic. Recently while
driving it in 2 wheel drive it made a loud grinding noise and started
vibrating really bad. It would not even move in 2 wheel drive. I put it in
4 wheel high to get it off the road, it was drivable but still ...

I have not had any air coming from the heater of my 92 S10 Blazer for months
now. You can hear a load hissing (vacuum leak) in the vent control area on
the dash.
I went to a junk yard and got a new unit, replaced mine and the leak is now

Can you tell me if there is a special way to change the ATF on my
automatic transmission?  It's in an 02 S10 Blazer 4x4.  It looks like
it needs to be changed, but I am curious if I should have the service
department do it.  I know I can drop the fluid and change the gasket

Just canvasing to see if anyone else has come accross their 4x4 not
engaging (lo or hi) when the dash console buttons are pressed?  I took my
truck to the dealer last week and they didn't sound too assuring about
what it was.  They said it was a computer module that was not ...

Won't go into 4H or 4L. Push button, 2H lite blinks as normal then goes
out. Can hear the usual "click" under dash, but no 4X. Have checked all
fuses. Tried grounding pin 13 for diagnostic code (on 4X button lites),
nothing.

Now that the snow has started to fall I noticed my windshield defroster will
only blow on the passenger side of the dash.  I do get alot of air also
blowing at the side windows.  I hear a whistling sound from the dash.  Im

I have a 74 Chevy 1/2 ton 4x4 with a fulltime front diff. I converted it to
part time with a set of Warn hubs. The problem is with the hubs in "Free"
position, the truck doesn't move. It feels like it wants to but does not.
After putting the hubs in "Lock", it drives fine. I talked ...

My "Service Engine Soon" light is on steady.It has a hard time starting and
runs like its missing.  I drive more than 35 mph and its starts flashing.  I
changed the spark plugs, the sp wires, distributor cap and rotor.  Any

The four wheel drive won't engage. When I push the switch the light blinks
an then goes back to 2 wheel drive. Looks like the transfer case and the
front axle both have a solanoid, could they be hung up?
Need help.

If I'm not in the right forum for this, please let me know.
I just purchased an 05 GMC 4500 4x4 cab & chassis, with a Duramax diesel and
an Allison trans. I was fortunate to find this truck during the "Employee
Discount" promotion this summer and saved a lot of money.

I have a 1986 K5 Blazer.  A new 290HP crate engine was put in about a
year and a half ago.  At that time, the mechanic deemed the stock
Quadrajet to be shot, so I put on an Edelbrock.
The Edelbrock is a 600cfm carb, with electric choke and vacuum

I'd like to have a tach for testing purposes and setting idle speed and
whatnot, but not necessarily a permanent fixture on the dash.  Are the
$30 cheapos found at Pep Boys easy to connect and disconnect?
Ideally, I'd like something that just clips onto a plug wire like a

I have an 05 short bed 4X4 work truck. Because of the extra springs in the
back it doesn't sit level and I see a little more wear on the front tires
than the back. Anyone have any thoughts on the best way to bring the front
up to level it out? It needs to come up 2-4 inches and ...
