Default engine codes...

Got my new heads, cam, and longtubes installed and have been driving it a couple days and i got a check engine light. Got codes 332- insufficient egr flow, 116 ECT sensor out of self test, 136 - HEGO sensor circuit indicates system lean (right HEGO). My guess for the first one is the vacuum solenoid for the egr is bad, second code im guessing the computer is confused on the engine coolant temperate due to the new heads and that will be fixed in the tune. Third one i just turned up the fuel pressure cause it said it was lean, i got it at 44psi. Im not sure on any of my guesses though, i was wondering if anyone had suggestions on any of these codes?

The EGR code means that the EGR position sensor is not reaching the desired voltage. In other words, the PCM actuates the vacuum solenoid but does not see the position sensor respond accordingly. The voltage remains too low.
The ECT code means that you ran a KOER self test with a cold engine
The HEGO code means that you have low o2 sensor voltage. It could be a bad sensor, an open or short to ground in the circuit or you really could have a lean condition.

So for the EGR code the sensor is likely bad? and I was wondering the right HEGO is passenger side o2 sensor right?

do a little more code research. HEGO is a general term referring to both. left bank is drivers, right bank is passenger.

oh well maybe the car is just running lean then, i dont know how both the 02 sensors could be bad they are fairly new.

haha yea it does. It likes to die all the time at idle though. Randomly it will die then you have to give it gas to get it going again.
