I need short-term fuel trim and while you are at it get me the reading of the o2 sensors. B1S1 and B2S1 needs to fluctuate continuously between .1-.9 B1S2 and B2S2 (if it has one) should be holding steady around .6-.7

Ask Your Own Car Question

plus the idle is way to high. you have a vacuum leak

Ask Your Own Car Question
Customer reply replied 26 days ago
idle usually drops after it warms up? It only ran for 60-80 seconds.. let me pull data and we can discuss if you still think there is a vacuum leak.. I sprayed and couldn't find any...

ok

ok replace the Bank 2 upstream oxygen sensor. that stft for bank 2 is crazy high and running super lean. you also may want to check the fuel pressure.

Ask Your Own Car Question

also, with the engine running, remove the oil filler cap and tell me if you feel suction

Ask Your Own Car Question
Customer reply replied 26 days ago
there is a little suction with cap removed. If I increase rpm the suction increases. This is slight suction had to take off glove to feel to it... Its running super lean I can barely stand next to it after Its shut off it stinks so bad...Please confirm 02 sensor B2S1 location... As I see it via diagram its right in front of cylinders 2,4,6 easily accessible...
This is why Cylinders 2,4,6 plugs were wet and black
Would you suspect MAF sensor if o2 sensor does not clear up issueDavid THANK YOU for your patience and time this evening... I will take care of your 5* rating

easily accessible yes. also, replace the PCV valve and clean out the PCV tubes. then we will go from there
