so i got up early to go fishing pull onto the free way and i have a bad missfire under load 
97 g16b 3 wire af meter where is the diagnostic plug? and which to pinouts do i short out? for codes. no check engine light on dash. changed plugs no difference removing leads one at a time causes rougher running as does doing the same with injectors so fuel and spark appear ok dont have a compression tester handy but i doubt it would of just burnt a valve for no reason. cheers peeps. |

How did you remove the leads and injector plugs when the engine was misfiring under load..... |

Misfire under load suggests to me a spark problem. I would be looking hard at plugs, leads, dissy cap & rotor button. |

Do what Jas has suggested first. No need to go all balls in and start with the more complicated stuff |

Wait til its night (dark) and watch for arcing on the leads. normally happends as you increase revs a bit. |
