Question about 1989 Honda Accord 4 Door
From about a year until November last year, my carburated 1989 Accord Idled at 1000 RPMs A/C or not. Starting about a month ago, the idle dropped to 500 RPM without AC. With AC, RPMs rise to 750. It should idle at 750, 800-900 with AC. I have never tinkered with the throttle ajustment screw. Car performs great through the rev ranges, just settles too low. Spark plugs only 2 years old, all fluids filled just to capacity, oil only a month old. Air filter good, Carburator clean. I don't exacty trust the temp gauge which reads operating temperature once warmed up. Could this problem be brought on by overheating? I'm especially confused by how the problem came about so abruptly, and how it sat at 1000, then 500 out of nowhere with no tinkering onvolved, or a change in performance aside froom the idle. In choke (warm up) process, car idles anywhere from 1200 to 3000; way too high. Contradicting symptoms. Any ideas?
