I just pulled my codes and it flashed this:
3 2 7
5 6 4
3 2 7
5 6 4
1 1 7
3 2 7
1 1 7
3 2 7.

I dont get why it repeated the first two, then went on and gave me 2 more(even though one was already given) without the seperator code(111) but thats the flashes I got, in the same order. If I did this right I should have codes:

327-EGR circuit below minimum voltage
564-Fan Control Circuit Failure
117-Coolant Temperature Circuit below minimun voltage/indicates above 245 degrees F

Sounds like I have some sort of an electrical gremlin. How should I go about troubleshooting this? My skills with electrical systems are low and I have no idea where to go from here.

The EGR code can come from a miscalibration in the EVR and EGR. A chunk of carbon keeping the EGR valve from seating can even do it.

One can remove the EGR and clean it out (takes about 2 minutes to remove it).

I would grab readings on the ECT at room/ambient temps and at operating temps (the car should not need to be running to do this). The ECT is a thermistor. See if the values you get correlates to known values at those temps. If not, check wiring and replace the sensor (sometimes the sensor itself gets cruddy since it sits in electrolyte).

Both of these codes could make the car run kinda crappy and lack performance. What are your issues?

Good luck.

My car idles somewhat high, but other then that drives ok, im still in the process of tuning it so it is by no means good or anything. On a side note, the EGR is deleted and I have it turned off in the Tweecer. The ECT sensor is a replaced piece, cant be more then a year old. Its from napa. The vortech bracket shifts the alternator extremly close to the ECT sensor, maybe a wire was damaged or something, ill go check. What readings do you want from the ECT? Im pretty sure I can moniter that with the Tweecer.
