[QUOTE="Kevin @ Wicked, post: 12332692, member: 18076"] Id like to say i had better news but I don't think its smart to try and finish calibrating this vehicle. When the car was 1st here I was only making shake down runs when the failure happened and had only 1 WBO2 in the bank 2 header (same side of motor that broke cam gear). The a/f was roughly 11.6 to 11.8 until the engine let go. Being extra precautious this time I disabled closed loop and removed the factory 02s and ran the vehicle in open loop with DUAL WBO2's (one on each bank). Bank 1 is roughly 1.5 points LEANER than Bank 2 the entire pull. My A/F for bank 2 is the same 11.6 to 11.8 while bank one is 13.0 to 13.2. To verify this condition i swapped WBO2 sensors side to side and the readings stayed the same, thus removing the theory that a sensor is bad. The reading lay right over each other on the tests. The power curve is exactly the same as before (only took it to 4500 once i saw one side not fueling correctly. I CANT STRESS ENOUGH the importance of calibrating with dual WBO2s for this very reason. I use duals 99% of the time, and insist on the bungs being welded in to be able to test this way. The vehicle will throw the 340 (cam sync code) within 5 miniutes of running. Exact description right from my ford documents..... P0340 - Camshaft Position (CMP) Sensor Circuit Malfunction (Bank 1) Im suspecting improper cam timing, time to dig deeper into it.........ughhhhhh :/ [/QUOTE]
