Sorry all, just need to vent a minute about the emissions system on my Jeep. I've now fixed the evap purge flow code 3 times and the CEL is back on again today! I've done everything from replacing the gas tank, leak detection pump / canister and fuel management system, replaced most hoses, replaced solenoid, replaced 3 cats and exhaust and this effin code keeps coming back (a new problem each time). Frustrating! Just waiting to hear back from the shop on what the new issue is...Anyone else have these problems?
