93 civic rough idle

I have 1993 honda civic that has 165,000 miles on it. Recently I have
replaced the head gasket, distributer, radiator, a bunch of hoses, and
gotten the cylinder head remilled. Well, anyways one day I was driving
home from work and my car suddenly went from running roughly to
running horribly to the extent that I had to pull off the road and cut
the now struggling engine. I checked spark, compression, and some
electrical and it all checked out but the engine still wont run in
idle, I have to hold the throttle down to keep the car sputtering and
barly running....so, now I have no transportation and no clue on what
to do next. so......if you have any advice....pleas "Go ahead"

 

could be catalatic converter or vaccume hoses..but if you have to hold
it to the floor sounds to me like converter unless timing belt
slipped.
good luck.....

 

since you've just done head work, check the cam timing - it's very
common for the belt to be incorrectly tensioned and for it to skip a
tooth or two.

 

How's the coolant level looking? Any evidence of another
head gasket breach?

How old is the O2 sensor? Is it OEM?
