I fixed my ac today on my 77, but when the clutch was engaged it idled extremely rough. So being the inteligent person I am I adjusted my fast idle screw, I increased the idle rpm by maybe 75 rpm I didn't use a tach but that's what it sounded like. Anyway the weird thing is my power steering started working, I replaced the old worn out pump a month or so ago and with a functioning pump it would not give me power assist so turnin stopped at any rpm was almost impossible as was turning under 5mph above 5 it got easier just because there was less resistance... so I put extra load on my engine compensated and ps now works. Any ideas. 77 comet 4d 250 i6 1bbl carb factory ac c4 trans. Work in progess
this is what should be on your car. it bumps the idle up when you turn the A/C on. I got mine off of a parts car Mike has...:Handshake...Mike Frank http://www.race-mart.com/product.asp?itemid=250783&gclid=CJC96-rxgr4CFU4R7AodRn4A-w
