thank you...... I got this code a number of times.. from a shop that replaced the throttle body.. and a friend owns a rather nice reader as compared to my real cheap one.. I hope we can keep chatting during this week I have little time to work on the vehicle... It is running... with the warning light on..... at my next chance will be to check the quality of the connections to the ECM and the IAC...hope to chat some more...
Pete does this seem reasonable..??
Pete,,, thank you for following up..... and please do again.... right now the vehicle runs quite well. yet the warning light is on and to get the vehicle smogged is impossible...I looked at wiring to components around the throttle body and one connector looks as though the wires took a beating at one time. how do I obtain a detailed schematic of the sensors? I have a computer/electronics background as long as a detailed drawing is available.
