Idle fluctuate when cold
Dear Friends:
I've got a '91 V6 MPV with 138k on it. I bought it from an elderly man who had it for its life under his meticulous care. But here's the problem...
I can start it with no problem but when it's cold in the morning, the idle would be 2300rpm for 5 seconds then drop to 1200rpm for a second, and then up and down till it's warmed up and comes to normal at 750rpm.
I checked the water thermal sensor, TPS, ISC, and Air Flow meter and they're all within the normal readings. I don't know what else could be wrong..
