o2 sensor and rough idling
Hey this topic mite have been talked about before.
On my ae86 trueno i see theres 2 sensors one near the top of the exhaust manifold and one near the bottom of the manifold. Its just that the bottom one is cut off and im wondering if i need it. At the moment it runs abit rich as i can smell the fuel coming out of the exhaust and im worrying about emissions when i MOT it near late december time. Also when the engine is warm or after a thrashing it struggles to idle properly it dips from 900rpm down to 5-600rpm and bounces back up. Ive cleaned the filter, checked vacuum lines and they seems to be fine any ideas ??? will try and get pics up on the sensors |

the second lower o2 sensor looking things is actually exhaust temp sensor for your cluster, has nothing to do with ecu.
Running rough when warm could suggest busted plugs and/or leads Idle hunting can be a dirty throttle body, or dizzy out but a tooth. Steve.....this is sparrrrrtan |

hmmm.... ic ic my lights was fine nothing came on when running
the porblem i found now is that its something to do with eleco or ground (i think) as it gets worse when i put radio, heater and lights on i have bought a grounding kit with voltage stabilizer just waiting for a gd time to put it on |
