RT76 Posted July 21, 2008 Share Posted July 21, 2008 OK, I need some help with a check engine light. The light comes on after about 5 minutes of driving no matter the conditions. I pulled the codes and get a 172 which is a lean code. I replced the o2 sensor, thermatic bypas selenoid, EGR valve, TPS and even the EEC. No luck! Fuel pressure is good, smoked the engine and found no vacume leaks, no leaks in the exhaust and it seem to run OK. I'm out of ideas...
