Ima douch lol sorry mate i seriously couldnt find it lol *does the Ncis Head slap* Well thanx for the diagram mate I did it all today and got the Rpm to sit stable still goes up and down 100rpm or so But it is alot smother But one more question It surrges when im at say 60khr and its doing my head in i re did all the vacume lines and she is a hell of alot smother and the vac advance on the Dizzy wasnt hooked up but she is now The surging hasent changed any of that at all so fudged if i know what it is But i have found that one of the dump pipe Bolts doesnt have a nut and i can hear it leaking But i dont think that would cause the surging The Airflow meter is working as if i un plug it dies lol |

the speed dosnt matter so much.... is it in like 2nd gear underboost ? |

Post subject: | Re: Vacume line |
No boost at all On boost or under load there is no problem lol ITs the complete oppersite lolz |

Post subject: | Re: Vacume line |
Ok let me Explain it a little better Say im at 60ks And i the idel is at 2300 rpm in 3rd and i keep my foot even just keeping it at that rpm and speed it jolts every few seconds like its wanting to go Its hard to explain as it doesnt do it under boost It feels like its a a mis but its not im so confused lol On a cold start it idels at 1500 rpm which is a normal cold start |

Xadous wrote: The Airflow meter is working as if i un plug it dies lol Sounds like your airflow meter is actually faulty, the service manual actually states: A quick check of the airflow sensor serviceability is to remove the sensor wiring with the engine at idle. If the sensor is serviceable, the engine speed will drop then return to normal. If no change is noticed in the engine speed, replace the air flow sensor |

If no change Well it does change it stalls lol I have checked for fault codes and there wasnt any for the a/f meter |

Post subject: | Re: Vacume line |
If you have zero fault codes the only thing left is to give the engine a thorough service. It might need plugs, leads, fuel filter, dissy cap and rotor etc. |

Post subject: | Re: Vacume line |
Done all that today lol besides the Rotor its doing my head in why it would have spiratic idle while sitting still sits around 1000 to 1500 and jumps every so slightly And while coasting with even presure not going any faster it jolts So yea .............................. Has anyone alse had this problem very search i have done its while people are on boost.... not while staying at 60ks or any speed at that matter |

Ahh ccrap Well i think you are right about the AFM My wife said just try it and the c ar idels almost the same as if the afm was pluged in actualy it idels smoother lol So Who in brisbane has a Spare working AFM they want to sell me or let me test it with to confirm |

Post subject: | Re: Vacume line |
Try driving the car with the AFM disconnected...........see if the problem still exists. Most cordia's will still drive well but lack acceleration enrichment as the ECU can't read it's airflow and defaults to a common value. If the problem remains it's not the AFM. |

Post subject: | Re: Vacume line |
So that means untill on boost it will be sluggish |
Author: | Bitza [ 12 May 2010, 22:13 ] |
Post subject: | Re: Vacume line |
No not really................the ECU just won't add extra fuel when the throttle is "suddenly" opened. The car should drive the same, given it's an AC fuel mixtures should be controlled, but if an AB will run a little richer. |

Post subject: | Re: Vacume line |
Ok well with the AFM pluged in it runs rough with it un pluged it will actually idle smooth if you understand me |
Author: | Bitza [ 12 May 2010, 22:22 ] |
Post subject: | Re: Vacume line |
Sure do..............please.......just drive it and see if the problem exists.......it won't hurt the engine. |

Post subject: | Re: Vacume line |
Well just went for a drive and it runs shit loads better lol But my Vac is around 15ish i have replaced all the vac lines so there is no leak Can the low vac be casued by the dump pipe being loose ? |

Post subject: | Re: Vacume line |
Your vac reading isn't that low.............most run around 15 - 20HG............sounds like you have it all sussed, just need an airflow meter. Most guys when they modify the cordia remove the "honeycomb" in the rear of the sensor in hope for a better airflow, but this disturbs the airflow past the karmen vortex generating rod causing erratic readings in the receiver from the transmitter. I have found this in many cordia's with your problem, including VR4's. Hope this is useful. |
