A nd the sound will tranfer all over the vehicle and make it hard to pin point sound travals . Look at your wheel bearings it can make a scarry noise but if you don't see fulid leaking all over the place and it shifts OK and runs OK then this is likely the problem

may be one of the radiator hoses.if not, it may be a blown head gasket or a freeze plug.

Some chevys have a sensor on the powersteering pump which can cause erratic steering..Not sure about your model..Look on the pump and see if you have a wire connector..

Check the next diagrams for specific locations (clikc image for zoom), in all engines check C1 or VCM (Vehicle Control Module)...

Hope this helps (remember to rate and comment this answer).

Do you know which cylinder ?

On a misfire...check plugs, plug wires, coil packs / distributor coil...and on rare occasions I've seen water from cooling system leak or trickle into a cylinder from a bad head gasket.

BUT

Lets keep it simple and go with the condition of spark plugs.
If they are good then look to plug wires and especially the connections.

Hope this helps...

Verify that you have fuel pressure the next time it does this, more than likely you don't. Cycle the key from off to on about 10 times before you actually attempt to crank it over. If it fires up after doing this then you have a bad fuel pump and your loosing system pressure over time beacuse its leaking down back through the fuel pump. Replace the fuel pump, fuel filter, and the fuel pump relay.

You will need to find the drain plug on the bottom of the trany, drain fluid , remove the bottom cover to access the filter you should have a repair manual. I am not sure if you can do it on that vehicle, you may have to get it exracted and replaced. Good luck

In your truck the brakes are hydraulic: the pressure from the oil tank is released thru a solenoid into a piston that pushes on the shoes with the pads. If the brake seems to be still partially engaged when the solenoid is disconnected then the shoes don't fully retract because either they were badly adjusted or the shoes are slightly seized and the spring isn't strong enough to pull them back.
In either case the brakes will have to be opened, cleaned, the support pins oiled and the shoes adjusted - a $300 at a truck stop. Leave that to them, it's a physically difficult and messy job.

if there is still some charge in the system, then you can just buy a recharge kit. it will come with full directions. If however there is no charge in your system then you will have to have the leak repaired and have the system purged and pumped down to a vacuum before refilling.

pull the shifter down to first when you stop then put shifter back into drive when you start to move...

The ac system should be between 30-40 psi. If your doing it yourself one small can should be enough. You can buy a kit that has the can with a hose the has a pressure gauge on it. That gauge will tell you if you have enough freon in your system. When you charge it make sure the ac is on full max before charging

its a cam sensor corilation to so try replaceing that as well but if you want light off disconnect battery for ten seconds but if problem still persist the light will eventually come back on.
