I have an 03 Mach 1. My car has had some weird problems over the past year which turned out to be the Quarterhorse unit screwing with my ECU and I had a bad coil pack.
Now that I have those issues sorted out, the car is running WAY better but I still feel like it isn't quite right. I pulled the codes and it is clean but it is failing 3 TIDs.
The TIDs that I am failing are:
Phase 4 Vapor generation max change in pressure and max threshold
Phase 4 Vapor generation max absolute pressure rise and max threshold
Cylinder events tested and number of events required for 1000 rev test
From the research I've done it seems like the phase 4 failures have to do with the EVAP system. I really can't find anything that will help me troubleshoot the issue.
Any help is greatly appreciated.
