My throttle body has an internal leak causing my new vacuum line to hiss. What could be the culprit?


Anything behind the throttle plate IS vacuum. If the hiss has developed after throttle body removal, check the gasket between the throttle body and where it bolts to at the plenum. Possible damage gasket

On a 84 porsche 944 where do the vacuum lines go to on the fuel rail 2 regulators. Where do they connect from regulators to where?


If it's not a turbo, the vacuum lines for the damper and regulator go to the vacuum nipple on the throttle body that is underneath the assembly and on the manifold side of the throttle plate. The other vacuum hose that is connected there is ported, on the non manifold side of the plate. If it has vacuum when the throttle is closed, it is on the manifold side. You'll need a vacuum tee to join them into one hose to connect to throttle body nipple.

1987 jeep comanche will stay runnning only when spraying carburetor cleaner in carburetor or when you pump throttle rapidly


Hello
It sounds like a glogged fuel filter or throttle body problem. Disconnect gas line at carb get a small jar or can to catch gas, hold gas line in jar and have someone crank engine, If you have good gas flow to carb then Its a throtle body problem, (Throtle body and carb are same thing just in case you did not know)could be electrical or mechanical problem at throttle body, Its usually electrical, fuel flow meter. Hope this helps

I have a 1987 s10. I need to figure out where the three vacuum line coming out of the transmission are supose to go. I bought the truck with just the vacuum lines hanging from underneith the truck.My 4...


The three lines hanging under the truck connect to a valve on top of the 4x4 transfer case, this is why the 4wd does not work. As for the throttle body lines there should be a diagram on the radiator support that explains that. You should have one large line that goes to the PCV valve, a small line going to the air cleaner, a small line connected to the MAP sensor and possibly another connected to a valve that controls the EGR valve. Your fifth line should connect to a port on the manifold that supplies vacuum to a tank that is the vacuum source for the HVAC control doors and the front axle engagement system. The axle engagement system is what the line hanging by the transmission under the truck is for.

How do you fix the idle on a 1990 isuzu trooper 4 cylinder, and where is the adjustment?


The idle screw is on the throttle body near where the gas pedal cable attaches to it. Not sure what sensors it has and less familiar with pre 90's cars but if it has an IAC or TPS could be causing problems. Clean the throttle body/carb.
