SOURCE: 94 Bravada that stumbles and stalls.. won't start when warm..

Try checking the exhaust flow when someone else is pushing down on the gas petal.The farther the petal gos down,the more exhaust should be coming out. I replaced my catalitic convertor at 44000 miles, it was clogged. I had them install a high flow type.

You will hear the AC compressor clicking on and off if working. If it clicks on and off all the time that tells you that the unit is low on freaon. If it clicks on and stays on the compressor is operating fine

SOURCE: the heater blows hot air

AC not working?

on a hot day it will blow warm/hot air if the AC is turned off or not working

If its hot air and AC is working then i would start by checking the fuse or relay. if its not the fuse/relay then i would look into the heater box there is a door that blocks the hot air

SOURCE: how do I adjust the

You don't. They are non-adjustable hydraulic lifters. GM's spec for torque on the rocker arm nuts: Tighten the valve rocker arm ball studs to 47 N·m (35 lb ft). Once the valve rocker arm nuts are installed and properly torqued, no additional valve lash adjustment is required.

Where is the pcv valve located ?

It is a hose with a metal/plastic made one way valve. Locate on top of your engine oil cover ( you could see it by the side of the cover ), the air which came from the over excess compress gas from piston, its called blowback.
The blow back gas goes through that PVC valve and goes back to the intake manifold.
Just look for the hose from the cover of the engine and connected to the airfilter intake hose! Look at the hose closely between end you will see the valve.
Hope that helps you out!

I have a 87 ford mustang 2.3 . The air conditioner will stop blowing from normal vents and blow from defroster vent. After a few minutes, it blows from the ac vents again.

There is a vacume hose going from the intake manifold to the passenger compartment. This hose has a check valve and a vacume resivore. When you steap on the gas the manifold vacume drops and the a/c goes to the default mode (defrost). The hose is small like a ball point pen's ink tube. sometimes the hose rots and leaks.

Pvc valve

it is small and threads into the lower intake near the front valve cover.
if your looking at the front valve cover from in front of the vehicle you should see a small hose that goes from the right side of the cover to the lower intake. the part the hose hooks to also screws into the intake. that is your pcv valve6bf35a5.gif
