OK...new info. A friend of mine came over, he had a diagnostic system on his lap top. There were no current or stored codes. As the engine was cold, we started it and ran some checks and found the fuel trim for both Bank 1 and Bank 2 Sensor 2 to be out of tolerance. What doesn't make sense is that there aren't any codes. Any thoughts? Could it be as simple as both post cat sensors being bad? Would those 2 sensors being bad cause the symptoms I'm having.
I've got spark, it starts fine every time and runs great for about 5-10 minutes so I also have fuel. The problems always start when the engine warms up to operating temp and the problems are always the same. Based on everything I'm reading I'm really starting to lean towards the distributor, I looked at it and it is the Hitatchi brand. I think Hitatchi is the OEM brand and am thinking that it's still the original distributor. I have paperwork that goes back several years and don't see where it has been replaced.
