I would check for a vacuum leak first. you can start the vehicle and spray starting fluid on the vacuum lines. If the Idle raises then you have a vacuum leak. NOTICE: do not spray starting fluid around or on hot engine parts or electrical elements, starting fluid has a very low flash point and will ignite very easily.

I have no heat coming out of my heater on my 1967 Buick Riviera, 430-4. Had engine overhauled. The mechanic may not have hooked the vacuum lines Really want to find a vacuum line diagram for the 67.


If you lost a vacuum line then the heater would let hot air out the vents with or without the fan motor running. Do this test with the engine up to operating temperature Touch both hoses with the heater on and temp control to the hottest position. Now check the temperature of both hoses. They should be the same. If not that indicates a blockage of water to the heater core. Test the water flow valve too. It can be plugged with rust or not moving to let water into the core. The core itself can be plugged too. If you really need a hose diagram, a Chilton's manual will be your source of information. The engine won't idle well with a vacuum hose off.

How do I fine the engine vacuum reference tube for the fpr on a 1988 ranger 2.9 L v6 Fuel injection


It will be an intake manifold vacuum tap. Check all the taps from the intake manifold. The fpr hose may be teed off from another hose to another device. Just trace them all down, and you should find it. There would be a vacuum diagram scheme on the emissions label under the hood- see if it is still legible.

Vacuum hose diagram 2006 buick rendezvous


I believe that the 2006 Buick (if it is a U.S. version) is required to have a vacuum routing diagram posted at the engine (usually on top of the fan shroud). Check there.

Vacuum lines


In 1989, all vehicles sold in the US were required to have vacuum routing stickers placed in the engine compartment. There should be a vacuum diagram sticker on the fan shroud. If it has peeled off, you'll need to find a shop manual and figure out which of the many possible diagrams apply (not an easy task).

1991 S10 2.5L throttle body idles to fast


A vehicle that old will suffer from brittle and cracked vacuum lines. I would say there is a bad, or several bad lines leaking away vacuum from the intake manifold. Don't forget to check the hose going to the PCV on the valve cover. A vacuum leak will also cause the engine to stumble and miss intermittently when idling.

2003 Ford Ranger 2.3 Diagram


 rough-idling engine can signal a number of positive crankcase ventilation (PCV) valve problems, such as a clogged valve or a plugged hose. But before beginning the functional checks, double check the PCV valve part number to make certain the correct valve is installed. If the correct valve is being used, continue by disconnecting the PCV valve from the valve cover, intake manifold, or hose. Start the engine and let it run at idle. If the PCV valve is not clogged, a hissing is heard as air passes through the valve. Place a finger over the end of the valve to check for vacuum.

With the engine at idle, vacuum should be felt at the PCV valve.
