rough idle
Posted: Fri Nov 07, 2008 1:48 pm
I have a red 173 with trimatic that runs great when warm. when cold its a pig. but regardless of whether its warm or cold it idles like crap at the lights, but only in gear.
when idling in gear it rocks the car from side to side like its a 350 with a very lumpy cam , put it in neutral or just touch the acclerator and its as smooth as a jap 4. is it timing, idle speed, or fuel/air mix ratio?
It also pings at full throttle at revs, or it may be just valve bounce due to old valve springs...don't know. could it be too advanced or too retarded?
or could it be advancing mechanism on the dizzy.....and dont tell me the problem is that its an FB and i should replace it with an EK or that i should repalce it with a grey!
