How do I adjust the valves on a 1998 old bravada 4.3 vortec

Here is the video. How to change camshaft position sensor in Chevy 4 3l v6

Hello Angela Hylton,

I always go for the fire, fuel & air first... but it starts... so
that's a really great indication... Could just need some fresh spark plugs... (ACDELCO R44LTS6) or a cold start valve ...

(get your OBD codes read FREE (See below).

~~ 4.3L V6 Plugged EXHAUST:

I've never found an elegant way to prove it...
So we'll just jump right into...

GET some liquid wrench Penetrating Oil and
soak the EXHAUST to CATALYTIC converter bolts
really well (couple of times).

If YOU OPEN the exhaust and the engine runs smooth...
you have found a PROBEM that will do both thing you are experiencing...

Now you have to figure if it is the CAT collapsing or a
MUFFLER BAFFLE blocking the out-flow.

(It's happened to me twice... but I'm pretty old)
((one converter & one muffler))

FREE... (to get you in the door)

Might be easier just to take it to a muffler shop...
and have them run your engine codes...

If you live in CALIFORNIA... we have DIFFERENT
parts, costs & requirements (of course).

((Somebody's BROTHER-IN-LAW is getting rich)).

But look up your prices on line... FIRST.
(know your prices BEFORE going in).

Hope this helps!!

It may be being hit by a rocker arm

On a Bravada, the engine is positioned so that you have 4 cylinders on your left and right in an 8 cylinder, and 3 on each side in a 6 cylinder. If you look on each side you will see separate valve covers, About 4 inches below these covers are where your spark plugs go in. They will be between your exhaust pipes, where they mount to your engine.

Firing order is as follows 1-5-3-6-2-4 for the Vortec 4200 series engine.

My manual is for 2002 Bravada with a Vortec 4200 Engine striaght line 6
Firing order is as follows 1-5-3-6-2-4

If the smarttrack light is on, trouble codes are stored. That's your starting point.

thats the code ... its releasing why though???
idling high GM trucks I found plugged catylac converters with bad oxygen sensors ...probable from what i seen on vortecs .....
and also if you got a vacuum gauge unplug egr top vacuum line put a vacuum gauge see if the gauge is erratic from the motor at idle...emission problem
if you unplug the egr line and the car leans out its a oxy sensor..!!!!

this would be your camber setting not the toe in. you can adjust the camber by removing shims from upper control arm but this will also affect other angles. best to just have it aligned

you can remove it with a swivel plug socket
