Bone said:Your long term fuel trims are high. Meaning you are running lean at idle and your PCM is adapting for it by adding fuel. Need to increase your injector offset with the VEC. Or with a Split Second controller or similar device.
Strange to see a big difference between the two 31.3 and 14.8, should be close to the same.
What are your short trim readings? Are they near zero with these (31 and 14)?
Could be high cause the PCM is not completed all readiness tests yet, need to do more driving tonight.
