I did some search and found alot of resources but the problem that I'm having doesn't covered by the resources. here it goes. I have a 2003 ford ranger. I'm getting a P2004 and P1000 code. I check the IMRC the vacuum lines are good I check for vacuum supply I am not getting any. I trace the vacuum line coming from the purge solenoid valve. Does this mean that my purge solenoid valve is bad?? I am not getting any dtc code for it. Please help I need to pass smog by saturday.
