Very common on these cars is a design flaw that leads the hose connecting the crankcase to the intake manifold to melt through, introducing a vacuum leak and causing a rough idle. it may be that. an easy way to check is to spray starter fluid down in the area slightly under the throttle body, also around the left front (while standing in front of the car) area of the engine. if it revs up, that means there is a hole in your hose.

There are only few things that cause this, 1st and most common is a restricted PCV (positive crankcase ventalation system) or a problem with the engines piston rings or a scoured cylinder allowing combustion pressure to leak into the crankcase.

How to remove air pockets in the cooling system.

when the car is cold, take off the radiator cap. Start the car and let it run for a while. While the car is running, watch the radiator opening for the antifreeze to start circulating. add antifreeze as the level dips down, when the antifreeze starts to spill out, (A Lot) put the Radiator cap back on, as the antifreeze was circulating, it was pushing the air out of the line,through the cap opening and when the antifreeze starts spilling out, it means the air is completely out of the line.

Why on my1997tahoe when you remove the oil filler cap truck will stall and lots of suction

Well -doing that sort of takes out the PCV System
doesn't it

Unmetered air comes in the oil fill hole & gets drawn into
the intake & leans out the fuel mix

You also got PCV system issues with high vacuum

Engine overheating after changing radiator and new cap, new thermostat....someone said to make sure air is out which I think I have done. No leaks, no blown head gasket that I can tell, no water in oil or...

Yes, you need to turn the heater on HIGH heat and the blower on high.. this will allow all the coolant to flow through he heater core and hopefully purge the air out of the system.. DID you reverse flush the entire coolant system.. including the radiator and block,, WITH the hoses off of each.. THE air is sometimes hard to get out... let it sit in the driveway and get hot..(with the radiator cap off) the coolant level and keep it full..when it starts to over flow.. put the cap back on..(MAKE SURE the reservoir is OVER FULL-topped off) and then shut the engine off.. wait until the engine is COLD before opening the rad. cap... the radiator should be full and have no air...CHECK and see how much coolant was sucked out of the reservoir...

See if when you remove the radiator cap when its cold it pushes antifreeze out if so you a head or head gasket problem you can also do this with putting a pressure gauge on the radiator and pumping it up to the recommended pressure usually says it on the cap and see if the pressure bleeds off. best of luck to ya

Why is my 350 chevy engine misfiring

What year and is it the factory engine? If it is carborated the choke may not be opening enough and is starving it for air and running rich. What spark plugs are you running? Have you replaced the vacume hoses and gone over the engine tightening(torquing) intake, carb and other parts?

My car seems to run for 3 seconds and dies, I have changed fuel filter just before problem started. After trying many times it will start, only to do same thing next day

Sounds like there is a leak somewhere [ loose fitting. o-ring or copper washer out of place ] letting the fuel run-back and letting air into the system. re-check you work.

Started overheating on short drives.

Check radiator coolant level (while it's cooled off) and see if you notice and leaks while cap is off. If coolant isn't all the way to the cap then you probably have air pockets in the cooling lines. Top of radiator and fill reservoir to correct level. To remove air run the car for a few minutes with cap either on but not closed or get a funnel that fits right into the cap opening (same as oil size) and run car. It will rid off all air but coolant will rise after air is gone or if no air present. Let it cool down for an hour or so and level should be at cap level or below. Top off if necessary and put cap on tight. If you see a leak then fix it immediately.

My oil light is on and I don;t know where to put the oil? Where do I put it, I have checked the dip stick but is clean so I need more oil going in?

on top of the engine there is a plastic cover with a 3 inch cap 2/3rds down toward the windscreen.this will say oel/oil this is the filler cap,only put in 1/2 ltr oil at a time and let it run down into the engine (60secs)before you check the dipstick.DO NOT OVERFILL.
1/2 way between the lines is fine.

Oil splutter while engine is running and oil cap is open

I mean if the cap is open, of course oil is going to sputter everywhere, because its running through there, lubing up the parts, like rocker arms and valves and spring.

Its normal.

Oil leaking everywhere air cleaner full of oil seems to be blowing up thru carbie still runs but oil loss cant be good.......Kevin

its called blow have compression leaking past the rings,which is pressurizing the oil and the pcv system which burns crankcase fumes,is now putting oil into the carb.put a filter that is not too restrictive in front so the air,not oil goes in the carb.eventually the oil will gum up the the 60s the engines had braether caps and did not reburn the crankcase fumes.
