Hi
I've got a new UK RHD March 16 reg Mustang GT manual reg AJ16GTO
I have a couple of DTC codes that keep popping up the car has done 5200 miles and recently the engine management light has come on three or four times. On investigation the code 0420 shows catalyst efficiency below Threshold bank 1 (only once it came up 0320 Bank 2)
I have a JLT Cold Air induction with the engine tuned to accept the mass air / 93 octane and an MRT Resonator delete H pipe from new and all runs beautifully, the codes started appearing about 500 miles ago.
Even after I put the stock air box back on with the stock tune and the engine light still came on showing code 0420, thinking it might be an exhaust leak I even had the exhaust bolts all re tightened and the light came on again on a gentle cruise but after a reset I drove for another 100 miles without problem.
Before I take it to the dealership What do you guys think
Cheers Andy
