Sorry about not responding sooner. I had composed a response on my cell, but apparently it didn't post. There are so many ads that show up and you can't get rid of them they just keep coming back, blocking what you are trying to write.
Anyway, these are the codes I picked up:
226 - Ignition Diagnostic Module (IDM) signal not received (El)
327 - EGR Valve Pressure Transducer/Position Sensor circuit below minimum voltage
332 - EGR Valve opening not detected.
Now, I hate it when the book gives different names to parts than what the manufactures call them, so I want to ask:
is the IDM the Ignition Control Module located in front of the battery? And, is the Valve Pressure Transducer/Position Sensor the EGR Vacuum Regulator Solenoid with 2 vacuum lines.
As for the IAT sensor, I know it monitors the temp of the incoming air, but if it is faulty, then it could make my engine have a rough idle and running, which my engine is doing now, plus there is also a high idle and not coming down very often which inconveniently causes the vehicle to move forward without foot on the gas.
