trans. has a rebuilt engine with 40,000 miles. I
recently had z smog done and passed but upon
return my idle was all over the place. Mechanic
tried to correct it getting it back to 750rpm's but
when i slow down to stop, it drops down to about
6-650 and sometimes stalls, Mechanic messes
with the timing and idle but it still not right.
