    hi all,
    Working on a 93 prelude sr. This car has a slight miss at idle and when you first hit the throttle. It is completely fine at 2000 and up. I am a tech at a small shop and have checked and tried many things so far including: plugs, wires, dist cap and rotor, removed intake and cleaned egr passages. Substituted known good ect sensor. Checked for vacuum leak, didn't find any. At the end of my rope here... Wondering about distributor, but checked spark very thoroughly and it seemed ok. Injectors seem ok, works perfectly at higher rpms, and lots of power after 2000rpm.
    thanks in advance
