Hello all.
Looking for some advise on how to diagnose / fix my 1991 accord. Its an EX-R automatic. wagon. (CD9 i believe its called).
I guess there are a few things.
1. there is an idle surge which happens after a few seconds of warming up or sometimes right away. it only happens in park so if i change to a gear and sit there with the break on it stabilizes.
(the following 2 things began occurring after we were messing around unplugging tubes and sensors while the car was running in order to see the effect)
2. the tachometer is all over the place when idling, it sometimes spiking to 4,5,6k rpm even though the car clearly isn't doing that. the timing of it is not in line with the surging at all it is just crazy random. when in gear its still weirdly unstable but not like in idle
3. when stepping on the gas while in idle the car gets all messed up, chugging stuttering misfiring. putting on the gas if anything takes away from the rpm and makes the car sound like its gonna die.
like the tachometer, if i put the car in gear and press the problem isnt as bad but it still stutters a little bit randomly.
is there something wrong with the computer or what?
(maybe worth mentioning i deleted the cruise control and air-con recently but it ran OK for a time since then)
