my 91 honda civic runs rougher and rougher as the engines warms. Once
warm, the engine will die if you put the top on the throttle body.
Could this be a bad TA sensor? What does a TA sensor do?

what codes are you getting? how old are the plugs?
 
i’m getting 17 flashes on the computer. It is supposed to mean a bad
speed indicator sensor. The book says take to dealer. Any ideas

sensor's in the instrument cluster on the 91 civic. buy a whole new
cluster for $40 at a junk yard. check for bad connection first though.

Are the rad AND the reservoir full? If there's air in the cooling
system, the sensors are not immersed, so the computer will shift the
mixture and timing way off when it warms up.

Weak, I hate to hear about Hondas that aren't working right. I depend
on them to stay running [unlike my Chevy]. If you are mechanically
inclined, I'd pick up a comprehensive manual. Usually they are symptom-
to-subsystem guides you can skim through. I've got about 30 pages of
tests to perform troubleshooting my idle surge issue while warm.
Experienced Honda techs are an option too :S
