Are there any problems with my VW Vanagon?
Make sure you watch the whole video from start to finish to find all the trouble spots that can affect these engines. From vacuum leaks, to bad spark plug wires, to bad grounds. These engines, with all the mileage and years on them, can encounter many issues.
Where is the throttle position switch on a Vanagon?
1. Idle/Full Throttle Switch on the throttle valve housing, commonly referred to as a “TPS” for “throttle position switch”—located under throttle body. We offer a replacement TPS here . 2. Throttle Valve Housing (aka Throttle Body): This part is almost always worn-out. We offer a re-engineered version here . 3.
How does the ECU work on a Vanagon?
Throttle Position Switch Digifant uses a single throttle position switch to signal the ECU when the throttle plate is fully closed (idle), or fully open (full load) position. This signal enables the ECU to determine that one of three auxiliary functions (idle stabilization, deceleration fuel shut-off, or full load enrichment) is required.
Where is the idle control valve on a Vanagon?
Idle Air Control (IAC) valve, also referred to as an “auxiliary air valve” or “idle valve,” located right on top of the intake air plenum, dead center top of engine. We offer a replacement IAC valve here. 4. Idle Control Unit (ICU), also commonly referred to as an “idle computer,” “idle relay,” or “idle control module.”

How do you tighten a choke on a carburetor?
Keep your eye on the butterfly valve in the carburetor throat. Turn the choke element clockwise until the butterfly is standing straight up. Then turn the choke counterclockwise until the choke butterfly fully closes (not too tight). Tighten the three screws that hold the choke in place.
Where does the choke go on a cold engine?
When cold, the little screw at the top of the throttle arm should now rest on the top step of the stepped cam. This sets the hi-idle, which is needed together with the choke on a cold engine to provide sufficient idle speed to keep the engine running until it warms up fully.
How does the automatic choke work on a car?
As the engine warms up, the coil voltage heats an element inside the automatic choke, causing a bi-metal spring to uncoil, opening the butterfly valve, and moves the cam to reduce the idle speed. Release the throttle arm so that the return spring snaps it back.
