Engine idle lopes up and down at 2,000 rpm's until it warms up no matter what the wether is. replaced the fast idle valve and that sensor that sits on the back of the intake manifold. someone help me please

Would you buy another car from this manufacturer? Yes

I have a newly acquired 87 acura integra ls, equipped with the standard 1.6 liter, that does the exact same thing- Idles high, fluctuating from 2500-2700 rpm, for a few minutes, then slowly decreasing to about 1000 rpm. I am hoping that a simple PCV Valve replacement/ cleaning will REMEDY this, however I am by no means certain as to what to do. Any feedback, comments, or advice is appreciated :D.

I have a 1994 Acura Integra RS. It has over 400,000 km's on it. It started to idle up and down, just as you described. I thought it was a sensor, but there wasn't a code or check engine light to be seen. I took it apart to do a routine timing belt replacement and I adjusted the valve clearances and it has idled normally ever since (three months, 9,000 kms ago). It's a simple fix and you are supposed to do it every 50,000km or so. I hope this helps!
