Question
My car failed inspection because of the code 1294.  What does that mean?

Answer
Hi Kevin,
I hope everything worked out with the code 1294 problem. Please let me know by using the 'thank/rate' tab below.
While you are there, if I might ask a favor: where it asks about a 'nomination for expert of the month' I would appreciate your entering a 'yes'. I am in a close race for that honor so every vote counts!

Hi Kevin,
It means that when you are in drive gear but idle, that the idle rpm is several hundred rpm different from the nominal 'target' rpm. I would begin by removing the air intake hose to the throttle body and using a solvent clean the throat of the throttle body, both sides of the throttle plate (move the acceleator linkage for access to the throat and rear side of the plate) and also the port of the air passageway at the side of the throat which is for idle air input. Check that the throttle linkage moves freely. Also look for any vacuum hoses connected to the intake manifold to be sure none are disconnected, and also make sure the ball in pcv valve in one of those hoses is moving freely.
See how the idle rpm then 'rides'. If that isn't sufficient, then the idle control circuits need to be considered, but those have a separate fault code.

PS Use the 'thank/rate' tab below to get back to me with questions/result, without having to wait for me to be 'available' to take a question. There is a space for comments to which I will respond. While you are there, notice the question about 'nomination to be expert of the month' for which if you would give a 'yes' answer I would be very appreciative. Thanks in advance.
