let me know if you find your problem I have a friend with the same problem He's replaced all three oxygen sensors tried a good known maf sensor. fuel pressure in in specs when running long term fuel trim is always at -25 should be 10 plus or minus plus 5 would be ideal . also checked coolant sensor
