kept getting p1107,p1108 codes, and after testing for leaks found one in a boost hose (one that runs over transmission-distributor intake), had to remove throttle body to access it... put it all back together, now had rough start with misfires, and also got a p0040 oxygen sensor swapped bank1 sensor 2, and bank 2 sensor 2??? wont really even start anymore...any ideas out there??

 

sorry meant to say vacuum leak
