Short term trim B1=-3.1 short term trim B2=-3.9 O2 B1-S1 70% @0.9v 02 B1-S2 60% @.760v 02 B2-S1 73% @ .930v 02 B2-S2 63% @ .8v Also new MAF sensor and in the last year plugs and wires, MAP sensor, intake gaskets
Possible solutions include: Inspect all vacuum and PCV hoses, replace if necessary Clean the MAF sensor. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling Inspect fuel lines for cracks, leaks, or pinches Check the fuel pressure at the fuel rail Check the fuel injectors, they may be dirty. Use fuel injector cleaner or get them professionally cleaned/replaced. Check for an exhaust leak before the first oxygen sensor (this is unlikely to cause the problem, but it is possible)
