idle problems on 89 accord lx
i have a friend with an 89 honda accord lx, carbureted in-line 4 with a 5 speed manual. usually the car idle's around 750 rpms, sometimes it will idle around 2500-3000 rpms, i'm wondering if this is a carburetor problem or what. any information would be helpful, i can give you a little more back story if you ask for it
Thanks,
Tim

Re: idle problems on 89 accord lx (filthy_shovel)
well...this is what i know...the car was having problems with getting really bad gas mileage, my friend took it to a shop who discovered that the hose on the PCV valve was pinched off,it's one on the intake right in front of the carburetor that runs from the engine to a little black and grey valve , the shop replaced the hose and things ran ok for a day. then the new hose popped off one side because the shop hadn't put clamps on it...after clamping the hose down, and replacing a vacuum hose that i broke while i worked on it, the car has since began this problem...it doesn't do it all the time, just some. Also the air breather constantly seems to get grease/oil in it that is coming out of the PCV hose that runs from the valve cover to the air breather.

Well, your pcv vavle is what is pushing oil back into your air cleaner. So replacing will take care of that.
As for hoses, you are looking for cracks, hardness, disconnections, kinks and such.
You may, if you want to isolate the particular problematic hose, while the engine is running, spray wd-40 generously on the hoses where they connect to something and listening to the idle. If the idle moves, then you have found your problem.
An engine with a vaccum leak will have a erratic idle because it is sucking air. By spraying them generously, the idle will go up or down and identify your leak. Works also for identifying intake leaks.
