Hi
My 92 Stanza has an idle question I have not found here.
111,000 miles, automatic tranmission. Tranny service about 20k ago. Timing belt at about 70k. New plugs, wires. Original owners.Typically runs great.
O.K. now that that is out of the way, here are the symptoms....
Car starts good. Idles good untill you put a load on it.
A/C on, in park, idle drops down to about 650 rpm, car shakes a bit. Put car in reverse, no change. Put car in drive and idle drops to around 500 rpm, then acts like it is being intermittantly starved for fuel. Engine sounds like it may stall, but does not. Rpm drops to about 250 then back up to 5-600, then back down again, etc...until A/C compressor cuts off. Then idle shoots to about 1500 rpm, then settles back down to around 800 rpm or so after about 10-15 seconds. As A/C kicks on and off, repeat symptoms.
Problem occurs mainly in drive. While driving around, can just barely detect an intermittant slight drop then increase in power, up & down, up & down, at about a 5 second interval. Vaccuum sits at around 20 inches at idle in neutral, 15 inches in gear with A/C OFF. When in gear, fluctuates wildly.
There is nothing even coming close to this in the Chiltons manual. That book reads like stereo instructions! Very hard to follow or look stuff up!
Thanks for any help!
