Major Idle problems
Ok, When I start my car the idle jumps up and down between 1k-2k rpm. I thought it was my IACV so I cleaned it.Well it didnt do a thing. It would only jump up and down when it would be in P or N , well today when I put it in R it started to do that and the car would act as if its going to stall out. I have no damn Idea what could it be, and I checked for any leaks in the vacum lines but there is none. someone please help me ! ! Thanks in advance
EDIT its a h23 prelude

Re: Major Idle problems
If it is doing it, even if the car is in gear, check your spark plugs. One could be fouled. Check the spark plug cables also to see if there are any burnt insulation.....

Re: Major Idle problems
is the vacum pump the big black thing on the back of the intake manifold? I have a spare intake manifold i might just swap them out. hopefully it would help.

Re: Major Idle problems
Why not do the easy things first. Try out what I recommended to you. It'll only take a few minutes vice a couple of hours on replacing an intake manifold.

Re: Major Idle problems
I just had this problem with my civic.. idles didnt jump.. but i was idling REALLLLY low and it felt like it was going to stall..
turns out an O2 sensor had shorted out and I had a crack around the O2 sensor in my exhaust manifold..
fixed those right up.. cost me around 800.00 and I was on my merry way.
