I had this code so I replaced my IAC.
Cleared the code and it came right back on (had battery disconnected while I was changing the IAC)
.
Cleared it again (used my scanner) after driving around for about 10 miles and it came back on 30 seconds after starting.
New:
plugs
wires
fuel filter
pcv
air filter
and now IAC!

Had a bad idle before the new IAC would dip down below 400/500 RPM's and would almost die, it would start shaking pretty good.

Now the The idle stays at 1100 in park and around 800/900 RPM,s in drive and seems stable and flat.
Is there something I am missing? everything seems like its connected wires rubber lines all seems to be correct.

HELP! Dean
