My Honda I just bought 116,000 miles from the internet, Seems to be a good
car, bought from a mechanic but as soon as I got home two hours away I
noticed something, it runs great except,its a 5-spd and  when I take it
out of gear, rolling to a stop light, or slowing for a corner it will idle
low enough to almost die then jump to over a 1000 rpm for a second, this
guy has done alot of replacement and I am wondering if he had this problem
why it was not fixed, He did claim to do a lot of maint. and he got it from
a customer and fixed alot and sold it to me. I am taking it to a honest
mech locally to give me an opinion but the more opinions the better any
ideas? Parts he replaced, engine and oil seals, timing belt, water pump,
converted A/C, brakes, drums/rotors axels, motor mount and more I am
forgeting.
