SOURCE: 1989 Chevy K2500 - idles fine but stalls out when put into drive.

Sounds like the injectors may be bad or just really dirty. You say that the truck is only used as a plow truck, so I would assume that it sits alot. If you dont add any fuel stabilizer to the tank, the fuel will start to degrade and the will gum up your injectors. One thing you can do is to pull the air cleaner assembly off and look at the injectors while the truck is running. Look at the bottom of the injectors while it is running. The injectors shouldbe spraying fuel with a fan spray of fine mist. If you see any drips of fuel in the this fine mist, that injector is at least dirty or on its way out. I would recommend that you change your fuel filter and then get some fresh fuel and the purchase some Seafoam fuel injector cleaner from your local parts store. Dont mess around with anything else. GET SEAFOAM. If it is in a plastic bottle it is not strong enough to do anything. Seafoam is in a metal can. Dump the seafoam in and run the truck as much as you can. This will help clean out the injectors.

SOURCE: engine stalls when put into gear, idle fines in park

This is a comon problem with GM cars.Most likely cause is the torqe converter clutch lock up solenoid.

SOURCE: Vibration when in gear, and stalling.

The problem is the torque converter solenoid. I had it happen on my 94 Cavalier a few years back and was a cheap fix at the local car mechanic. What happens is the transmission warms up and hits a certain speed where the solenoid engages, but then it sticks and won't disengage until it cools down sufficiently. When it sticks, it causes the car to shake when slowing down and will snub out the engine if you come to a stop.

SOURCE: I have a 94 v6 camaro and am missing a vacuum line

Sounds like, there is no power brakes if the hose is not connected to the brake booster. There should be a massive vaccuum leak in the engine. The brake booster vaccuum line is a major vaccuum. You should hear a hissing sound when engine is running. Find the hissing noise and replace as nessessary.

SOURCE: Slight air hiss or sucking sound near brake pedal and no

It maybe, I don`t know the vehicle personally but on Trucks and Buses, when this occurs, it usually points to the master cylinder piston seals which moves in and out as the foot pedal is operated. Does the hiss alter as the pedal is pushed down?? Does the hiss reduce or increase as the pedal is pushed down?? If it does, I think you`ll find that it`s this air seal between the piston and cylinder that`s failing and not the servo. Whether you car works the same way, I don`t know but I presume it must. Ian

I have a 2006 GMC Envoy, idles rough at a stop when in gear, but levels out smooth when in neutral. Drives smooth on the highway.


check for a vacuum leak in the brake booster. Check this by just allowing the engine to idle with the hand brake on and if ok then put your foot on the brake and if the idle changes then there is an air leak in the booster.

Break pedal is extremely hard to push and i can hear a hissing noise, also my truck will not idle well in gear but when you put it in park it seems to revive its self.


Check for vacuum line leak by removing the hose from the booster and plugging off. If the engine settles down and runs ok then there is a problem in the booster controls or diaphragm. Replace the booster if that is the case. Hard brakes is the result of no vacuum assist when you put the brakes on and the noise is air escaping into the manifold through the hole and making the engine run rough.

Wont idle


I had an '87 Celica doing the same thing and it was an intake manifold gasket that wasn't sealing-pulling in a lot of air. A lot more than a vacuum hose leak, which would only raise the idle a bit, but not cause the surging you are having and that I had. So check for a large air or vacuum leak. A rip or hole in the large intake boot may also be the source.
To check the manifold gasket, get a spray bottle filled with water and have someone keep the engine running at around 2000 rpm or higher. Soak the area all around the intake manifold gasket, wet it down pretty good. If any leaks are there, the water will get sucked in and cause a noticeable stumble in the engine, may even try to die. Check all hoses for vacuum leaks too, the large hose to the power brake booster.
If it's not a vacuum leak, try unplugging the MAF sensor and see how the engine runs. If it settles down, clean or check the sensor.

2005 dodge neon - revs high in park nuetral and tough to push break pedal down. mechanic doesn't know what it is. Anyone have this problem resolved before? Thanks


sounds to me like you have a vacuum leak. When you lose vacuum the brake booster doesn't operate right. You need to go too a different mechanic. Could be the idle selonoid staying open or even a bad brake booster or vacuum hose came off.

ENGINE IS SURGING AND WONT IDLE


The MOST LIKELY cause of an engine surging and refusing to idle is a vacuum leak. Check all vacuum line connections. You can also pinch rubber vacuum hoses off one at a time near the intake manifold to see if the engine idle changes, - don't forget to check the hose to the brake booster. If pinching off the booster hose fixes the running problem it is possible that the booster itself is leaking if you can't find any leak in the hose.

You can check for vacuum leaks at the intake manifolsd gaskets and throttle body base by squirting some carburetor cleaner around these areas. If you spray this into a vacuum leak area, you will hear a change in engine RPM.

Where would i install a vacuum gauge on a 1994 3.4l v6? The fitting at the back of the motor is about impossible to get your hand in between the plenum and intake.

Dies when shifted into gear


May be having problems with engine vacuum leaking. Pull the large hose going to the vacuum operated brake booster and block off the hose end with a cork or other plug. Start the engine and see if it runs more smoothly. Set the emergency brake and put in gear--does it idle smoothly? If so, then you likely have a bad vacuum leak within the booster unit. Restore the vacuum hose to the cylinder and arrange to replace the cylinder.

Sounds like a vacuum problem with the transmission. Modulator maybe?
Take it to an auto trans specialist.

Engine stalls at stop lights and stop signs


sounds like the torque converter lock up might not be disengaging. You might also want to check for engine vacuum leaks. Does engine idle smoothly when in park or nuetral ? if the idle is good I would suspect torque converter problem.
