my engine management light is on in my 24v and after a plug in it came up "low voltage to air mass meter". would this be a wiring problem or an ecu fault? i have 2 air flow meters with no difference between them. its runs pretty jumpy and wont budge with the pedal down only with light acceleration. ocaasional black puffs of smoke, maybe running too rich?
Have you checked/cleaned the ICV lately &/or done a woowah test on the lambda?
