Can't Keep It Runnin!?!?!

[1993TaurusSHO]

OK I need help cause this car is ******* me off.... A little while ago I noticed my car just won't stay running when I come to a stop..especially fast stops...it sometimes will stay running if I come to a slow stop. I have recently changed the intake gaskets, valve cover gaskets, timing belt, water pump, fuel filter, cam and crank seal, cleaned the throttle body and intake. When I changed the fuel filter the fuel that came out was brown so could it be dirty injectors or vacuum leak or what.. I am hoping somebody can help me find this problem. I am about to go run codes. I will post them as soon as I get them... Thanks for any help.

Codes

Key On Engine Running - 172,136,232,233,853 ??,652,163 ??, 21

First off all the codes should be 3 digits. So the KOEO is probably
335 - DPFE sensor voltage higher or lower than expected.
551 - IAS circuit failure

The 551 is the control vavle for the idle speed. If you have an MTX car it is possible to take it apart and clean although I've never had any luck with that. ATX control valve aren't cleanable. Look to pay $50-80 for it. Make sure you check connections and stuff before replacing it.

KOER:
172 - HEGO sensor indicates system lean (RH).
136 - HEGO sensor indicates system lean (LH)
232 - No corrisponding code
233 - No corrisponding code
853 - No corrisponding code
652 - No corrisponding code
163 - No corrisponding code

Try running them again. Make sure not to count the seperator pulse.
