honmusa: How much is the engine now? Plus transmission too? |
Re: Autologic workshop compilation of daunting car issues :Diagnosis and fix by praxisnetworks: 10:14am On Sep 30, 2017 |
honmusa:However I hope you know that some cars will refuse to revv beyond 1500-2000rpm due to a variety of reasons? Most of which do not require a engine change!! BMW, Mercedes, etc |

Costee:categorizing P1130 has a reference means that there is nothing wrong with the sensor involved it is working perfectly !!Engine computer automatically triggers some DTC if it cannot place where the issue is coming from !! I hope to have my own YouTube channel very soon when all this can be shown practically cos something cannot be shown on forum except live video but I will still send some screenshot to prove this assertion!! Hope the issue of P1130 has been settle once and for all !! |

praxisnetworks:what i don't want to engage is unending loop of argument cos all these had been addressed in the report !!! |
Re: Autologic workshop compilation of daunting car issues :Diagnosis and fix by praxisnetworks: 10:20am On Sep 30, 2017 |
honmusa:I may be changing one soon. Please what's the cost of the engine and transmission? Thanks. |

honmusa: You missed my modified comment because of the ban on the other moniker, the P1130 should not be over looked at all in actual fact the symptoms you describe of the car actually points to that direction. The swirl valve is the cause but not because it was damaged but because the ECU was faulty which left the car in limp mode. The same guy who tackled this issue change the cam sensors, plugs, air filter, played around with MAF. The actual culprit was ECU and after that the car passed the 2rpm on its own 1 Like |

InspiredM good to see you here...

nurey:Nice analyses but the intermittent misfire is actually the cause of the reference code which I will prove to u later !! |
Re: Autologic workshop compilation of daunting car issues :Diagnosis and fix by praxisnetworks: 10:34am On Sep 30, 2017 |
honmusa:I don't want to engage in flip flops...but I strongly believe that engine change is an Overkill. But you're yet to answer my question about the engine and transmission cost. |
Re: Autologic workshop compilation of daunting car issues :Diagnosis and fix by Nobody: 10:38am On Sep 30, 2017 |
honmusa:In what way have your tests demonstrated the code has reference value, when you didn't deign to look the valve over. No sir, you've not done enough to sound the immodest claim that the issue has been settled with all finality. |
Re: Autologic workshop compilation of daunting car issues :Diagnosis and fix by Nobody: 10:44am On Sep 30, 2017 |
honmusa:Nice too. I assure you the reverse is the case. Misfire is generic, caused by sundry metered gadgets. |

Costee: Nissan giving technicians headache since 1800BC , I think pointing diagnosis in the right direction is better than condemning his approach (no insult intended ooo) Honmusa is a pro in his work but we are all humans, we could actually miss a step it doesn't make one bad, it's just what it is. Honmusa, you have to prove beyond reasonable doubt that the P1130 isn't the culprit please in a lay man's term you know I am too techy. Cc GAZZUZZ, mayor2013, Kingreign make una come learn work |
Re: Autologic workshop compilation of daunting car issues :Diagnosis and fix by honmusa(m): 11:07am On Sep 30, 2017 |
nurey:your own analysis is damaged ecu or swirl control ?? |
Re: Autologic workshop compilation of daunting car issues :Diagnosis and fix by honmusa(m): 11:11am On Sep 30, 2017 |
nurey:actually i like this cos we are learning ,i will do another case to prove that swirl controls nor ecu are responsible !! I have actually solve similarly issue if u must know cc:ivoryhouse In addition that particular cylinder is already soaking plugs heavily !! |
Re: Autologic workshop compilation of daunting car issues :Diagnosis and fix by Nobody: 11:47am On Sep 30, 2017 |
honmusa:That's the spirit, though nurey certainly read between the lines (for which he will be trounced soon ) "alleging" that I was condemning your approach. Since this engine is about to be buried, let's have the next case study |

honmusa:How much for the engine. |
Re: Autologic workshop compilation of daunting car issues :Diagnosis and fix by honmusa(m): 12:06pm On Sep 30, 2017 |

honmusa:Plus transmission? |

Costee: Make him bring the engine come your crib so you can show me the way, at least it will get my mind off Nigeria problems |

honmusa: If it's one thing I learned from my Nissan Almera, it is perseverance and patience. Nissan diagnosis is test, confirm, retest reconfirm, ponder about result then retest again something as little as a wire off the socket can give symptoms not expected. I actually sort out the code since Costee kept on hammering it I just wanted to know what it was about. The result came out as swirl valve, I don't even know what that was but no knowledge is wasted (I followed the links because this car type could be my next ride God willing). The link I followed had same steps you said had been taken before and even more were added by a Nissan expert to the solution but the car owner kept telling him those things had been done and no improvement. The car owner came back that he just changed the ECU Pam the car was as good as new, my thought was now that if the ECU was bad why will it be able to store DTC until I remembered someone had an issue with a kia cerator of plugs and misfire and GAZZUZZ said he should change the ECU that it was the culprit. Sometimes car diagnosis can be funny, it's not mostly about the amount of gadgets you can lay your hands on, it's about the benefit of a doubt. Don't over look that code. |

Case 2 :Toyota Rav 4 2006 Customer complaints :Coolant level is reducing per 1 litre for every 12 km with no obvious leak . |
Re: Autologic workshop compilation of daunting car issues :Diagnosis and fix by GAZZUZZ(m): 12:38pm On Sep 30, 2017 |
a misfire oncylinder 4 will not cause vehicle not to rev past 2rpm. I like your approach to solving issues, but you are most likely going to have same result with a new engine (been there done that on same vehicle) Look beyond the misfire. 4 Likes |
Re: Autologic workshop compilation of daunting car issues :Diagnosis and fix by honmusa(m): 12:50pm On Sep 30, 2017 |
GAZZUZZ:like I said earlier ,I have a similar case before ,it was a misfire issue from a single cylinder that the car refuse to rev beyond 2000 rpm. so from that background knowledge I know it possible for misfire to cause this issue even without any diagnoses .But I am not even using that as basis for this one as I have already done my own critically work on it before making my definite diagnosis. however I have already sent for the car and I will make open all my test on the electrical on Monday |

GAZZUZZ:thanks |

nurey:We will revisit the testing of the solenoid on Monday !!! So the focus of the test and experiment is if it possible for the P1130 to be responsible for the rev issue !! |
Re: Autologic workshop compilation of daunting car issues :Diagnosis and fix by honmusa(m): 1:16pm On Sep 30, 2017 |
menstrualpad:Not possible sir unless something is the wrong with them !! |
Re: Autologic workshop compilation of daunting car issues :Diagnosis and fix by menstrualpad: 1:22pm On Sep 30, 2017 |
honmusa:So how much would it be with transmission? |
Re: Autologic workshop compilation of daunting car issues :Diagnosis and fix by honmusa(m): 1:26pm On Sep 30, 2017 |
menstrualpad:250k |
Re: Autologic workshop compilation of daunting car issues :Diagnosis and fix by menstrualpad: 1:28pm On Sep 30, 2017 |
honmusa:Is it same price with the VG33 in the 99 Pathfinder? |
Re: Autologic workshop compilation of daunting car issues :Diagnosis and fix by honmusa(m): 1:28pm On Sep 30, 2017 |
Before I get the swirl solenoid test maybe we get some background information on it so that testing will be easily understood by all and sundry !! Swirl control is basically a variable Intake manifold control system just for performance purpose!! There a lot of implementation of variable air intake control system by different manufacturer namely BMw:DiSA Toyota :variable Induction system ACURA:Variable Volume induction Etc |
