Hello everyone and thanks for taking the time to read this! I have a 1989 Toyota Tercell, 5 speed and I am having this problem. The car starts up fine drives fine for the most part, but when I come to a stop light or when I stop the idle gets really low as if the car wants to cut off. Sometimes the car does cut off. I have to leave it in neutral and apply gas so the car does not cut off when stopped. This happens whether I have the AC on or not as I have tested both ways. I have always kept an eye on the Temperatures and Coolant levels and car has never overheated. The only other thing I have noticed was that when I am driving sometimes the car will sputter like it is not getting any gas to it for a moment then pick back up again even while I have the gas pedal pressed. This is only happens randomly however. Any assitance you can provide to me would be greatly appreciated. Thank you in Advance for any input.

Most cars have an idle speed motor that actually adjusts the idle, even back to the 80s. You should see it move as idle gets too low. Could be the motor or a sensor. At its age probably the motor - just guessing, Tom

This happens to my very old 1981 Toyota Corolla KE70 (1,290 cc, 4K engine, Malaysian market), every now so often too. The idle speed on the Aisan carburetor for this type of engine is adjusted by only a simple screw, tensioned with a spring. There is no idle motor. I just changed the carburetor again, to a new one meant for the 1,166 cc, 3K engine. You may note from my earlier post that the first new carburetor which I had installed last year was giving trouble with the vacuum outlet, so I had to replace it again a few weeks back. I've just found out that both carburetors are likely made in China by this company, hence the lower cost and inferior reliability ! http://www.kinzo.net/english/product/index.asp I've read in another forum that the Aisan carburetor has a kind of "power piston" in the idle circuit, whose purpose is to enrichen the mixture during low vacuum conditions, like idle. If this piston jams or functions erratically, like due to micro-abrasions in its chamber over time, the mixture will become way too rich and the engine may well sputter or die off. The user who posted this (in some Suzuki jeep forum, I think) was pretty skillful, and managed to hone the chamber and replate the piston or something. Otherwise, the only option may be to send the carb to shops for rebuilding. But it may also well be the idle motor as Mr Greenleaf suggested. You should check this first. The Aisan is a real problematic carburetor actually. Pretty poor on fuel economy too. Possibly that's why some Toyota users switch over to Weber carbs, but then there may be throttle linkage problems. I've been thinking of sending my original carburetor to this shop for rebuilding, but it's pretty costly, about US$250. Still it's the cheapest I could find, other places in the States quoted me up to $325. Nobody in Malaysia knows how to rebuild carburetors. http://carbspec.com/ They sounded quite professional when they replied my enquiry.
