Car starts and runs great, but when you put on the brakes the rpm's go below 1000 then 500,200 then dead. Itstarts right back up and away you go until the next stop.I thought vacume break booster leak, so I was driving down the road at 35mph with a stop about 300 ft, put the trans in neutral and maintained 3000 rpm and came to the stop using only the parking break, (don't try this at home) the enjine still died. The car idles fine but seems to hate braking pressure, its a 92, its not that smart!

Check idle air control valve operation. Also check for vacuum leaks.

Thank you so much for your answer.I have another problem and I think it's related to the first one, you see the incline of my driveway? With the car backed into the drive the car won't start at all.I have to coast down to the level of the street and it starts right up. It's not low on gas. I removed the AICV took it apart cleaned inspected it all o-rings ok though I don't understand it's function car still does the same dying at stops or rear-above-front incline Thanks, TEKSUN

Teksun,

the valve allows air to bypass the throttle plate when the throttle is closed. You have to clean it with intake cleaner to remove all the carbon build-up inside the valve.

A tip would be, when the vehicle doesn't start or if it stalls, try holding your foot on the accelerator very, very lightly, this will open up the throttle plate and allow air to come in. If the vehicle doesn't stall when you have the foot on the accelerator, you have a faulty IACV. Sometimes cleaning the valve doesn't work, and you must replace it.

Back in october I asked this question to you and all my my auto tech friends and the answer was unanimus, IDLE AIR CONTROL VALVE! I broke down and bought the two part assembly. Didn't help a damn bit. Turned out to be the fuel pick up sock on the bottom of the fuel filter inside the fuel tank.(I tried this at home) Car runs GREAT, TEKSUN
