I've already posted in the xtype section but i just wanted to know if he was able to find a sloution for his car coz it might help solving my problem coz even if they are different types sometimes the problems are common...

 

For general posts don't put up yet another message. Instead use Search and do the reading. Posting in the wrong section on purpose is not good, to use British understatement.

 

1998 Jag xk8 standard engine 99,000 miles
What would be your list for running rich on both banks 1 & 2?
My plan is to replace MAS, air filter and clean throttle body.
Have replaced all four oxygen sensors and the aiir tube from intake to throttle. Did the smoke test and replaced two hoses.
Went from running lean on both banks to rich on both banks.
Engine quick start and runs with ck engine and ABS lights on.
Engine rebuilt at 65,000 miles; transmission at 93,000..
