1996 Suzuki Sidekick Geo Tracker 1.6 16v Idle Air Compensator Thermal Test

Hi there!
Today we're testing the throttle body Idle Air Compensator on a 1996 Suzuki Sidekick 16v 1.6. We see that it is opened when cold as we can blow through the port, but we want to make sure it closes when at operating temp for proper idle and hot start.
The video shows it fairly well as it's a simple little test.
This can help you diagnose difficult hot start, or idle issues you may be experiencing.
If you have any questions, please leave them in the comments and I'll answer them as quickly as I can.
Thanks for watching!!

Do you know if these can be repaired or rebuilt? I have one that is leaking coolant into the throttle body.

I think it depends on where the leak is. If the coolant to air passage corroded through, I'm not sure...possibly TIG welding up the holes and a little machine work? The short answer I think is yes, but how much work, I'm not sure. If the fluid filled expander leaked, I think it would be easier to find a used one and clean it up. Good luck!

Hi:) I have a suzuki sidekick 1.6 16v 1995 , when its cold weather when i start the car my idle is around 800 but as the engine warms up the idle goes to 1500-1600 and if the weather is colder even more then 2000. Can this be the reason?

[@whiteknightandshorty]

Hmm... that sounds counter intuitive and backwards than what is intended, but it is possible, yes. The 16v has two water temperature activated sir flow compensators that may be an issue. You might want to make sure the secondary ignition and timing is accurate and where it should be, and that you don't have any other issues with the ECU or check engine lights etc. Then you might have to move onto manually testing the various sensors and their functions, and then make sure the coolant lines that branch out from the water pump return rail under the intake that travel through the smaller water lines through the intake and the two compensators are not plugged and are free flowing. Those bring the warm coolant through the two manual water temperature activated air compensators that make sure the programmed ECU delivers what it should when it should. If they are not opening, usually the engine doesn't idle correctly, or searches for the correct idle. Also, there is a procedure to set the idle air bypass screw on the throttle body, but if you haven't tou8ched it, I would not suggest messing with it, as it needs a few special tools to adjust it properly. Make sure you have access to some kind of shop information such as Alldata before you begin to adjust or attempt to correct for various discrepancies. Knowledge is power and information is crucial! Good luck!

@@whiteknightandshorty someone messed with the idle screw of my 94 sidekick, the one located on top ofertas the TB. Where can I find those instructions? As you screw it in, the engine wants to stall. If it is out, the rpm go up. Thanks.
