'92 Toyota 4x4 22RE, No Idle and Stalling
Q: I have a 92 Toyota
pickup w/ 145k miles. I have been having idle problems for about 3 months
now. I have replaced the plugs, wires...set timing (which was difficult
as the car was idling from 650 - 900 RPM). All in all, the car starts
fine and the tachometer goes straight to 1400 RPM. It stays there until
I engage and start driving off. As the car approaches normal operating
temperature and I depress the clutch, the engine quickly dies. It is as
if it is either low on fuel or getting way too much air...What else can
I check and how?
vehicle seems to have all the symptoms of a vacuum leak. With the age
and mileage on your vehicle it would not be out of the norm for a problem
like this to occur. There are a variety of ways to check for vacuum leaks.
Some of these procedures have been known for their quick and affective
hair removal. On more than one occasion Ive experienced remarkable
eyebrow hair reduction that can occur with the use of these procedures.
In our shop we have this little machine that is connected to the intake
manifold and pressurizes the manifold with smoke. This great little smoke
machine has allowed my eyebrows to grow to their full potential and is
really affective at locating vacuum leaks caused by broken vacuum hoses
or failed gaskets. As for using the other procedures to find vacuum leaks?
I suppose you could call it fun to watch as long as youre not the
one banging your head on the hood and slapping away at what hair is remaining.
