Wrong button! I get this Yukon, the customer complaint is: When i feel up my truck and start it. It is hard to start. I pulled codes and got a B1 lean, B1 rich, B2 lean, B2 rich. This tells me she has an issue with her EVAP system. Pids on the scan tool says the fuel tank pressure is at -2.95 in H2O and the purge valve was at 11%. So I commanded the purge valve to 0% and pulled the line going to the vent valve to see if a vacuum was being drawn on the system. And there was. I replaced the purge valve for $85 total. Later i found out that she had just spent $1865 to somebody else for this same concern. That just goes to show that if you have it done right the first time and stop trying to cut corners. Then you (might) not have to pay as much.
