The 170 code is a general fuel delivery code that the computer hasn't determined whether its too lean or too rich. It could be either. A number of factors determine the fuel trim. It is a code that sets after the computer sees a problem over a period of time. DTC P0139 — O2 SENSOR CIRCUIT SLOW RESPONSE (BANK 1 SENSOR 2) Usually the cause of P0130 is a bad oxygen sensor, however this isn't always the case. If your o2 sensors haven't been replaced and they are old, it's a good bet that the sensor is the problem. But, It could be caused by any of the following: Water or corrosion in the connector Loose terminals in the connector Wiring burnt on exhaust components Open or short in the wiring due to rubbing on engine components Holes in exhaust allowing unmetered oxygen into exhaust system Un-metered vacuum leak at the engine Bad o2 sensor Bad PCM

To wrap up this thread for others: Per wtdash You see THIS? I'd see if it'd work on your newer model. Saves a lot of work. Per 86bratman The workaround will work, I've done it before. But if you want to make it oem the thread is m20x1.5 for the phase 2 egr bung. Per ocei77 The posted workaround works, but there is a simpler way. Cut the egr tube in half, rotate it 90 deg. facing pass side. Take the iac hose and the cut egr to auto store and get a foot of the size that fits it. There is another fitting that will go over it that will make a tight fit into the iac hose.(not sure of size) If you don't have another iac hose around get a foot of 3/4" ID hose of any type. Get a 3/4" T barb. Plastic is fine Hose clamps is all else you need. Lay it out as you install it so that you cut the iac hose in the right places. Will post pics as soon as I get to the car that the mod is on.

Does anybody have the drill bit and tap sizes for an EGR port for a 2003 2.5 left head? Caboobaroo mentioned he had it, but he has been off line for a couple of days. Have the head and need it ASAP. I will take pictures and post this once I have the proper drill bit size and tap size for people in need of this in the future.
