Hey guys

My car has been misfiring for the past 2 months and after going to 3 different mechanics and even after changing a number of parts its still no good. However the last mechanic thinks it is most likely either the O2 sensor, Crank Angle Sensor or Computer (eManage) thats causing the problem because the car missfires after 2000 revs only and especially when the engine is hot - it sometimes won't even allow it to power on when its hot so once cool, it will power up but still missfires. Anyways, i'm getting the shits now and I really want this fixed. I'm getting it taken to this place DynoTune in moorebank and was just wondering if these guys will be able to sort it out.

Thanks guys

these guys are shit talkers.

they want to charge me $400 and they have not even found the problem yet. The bloke on the phone said they will do a computer test which will take an hour and a half at $80p/h and now its $400. Their solution is to buy their EMS computer and get them to tune it all up $2500 plus the $400. And I bet then, the problem will still be there as the problem is not with the computer to begin with. I knew I was gona run into this shit by going to a "accessible, nearby place". Unbelievable.

Whether you consider this a whinge or advice, DO NOT TAKE YOUR CAR TO DYNOTUNE & EFI

They are a RIPOFF and have "diagnosed" the 34 with same results as I suspected over 2 months ago, only they charged $400 (without advising me of these costs). Will be taking this to fair trading.

that's such a typical story. so many rip off tuners around.

i recommend C&V Performance at caringbah.

i've used them. they know their shit. and they really look after their customers cars.

also, they dont charge like a wounded bull. and if they quote you a price, and run overtime, they stick to the agreed price.

obviously this is my personal experience. i'm very happy with them.

HA HA,the c**ts have no clue! I went to them years back and they tried to rought me aswell (jason the owner) told him to snap out of it before i snap his jaw,f*kn rip off dogs :)

damn darko.your car still has the same probs.

yeah you should get greg at autosport to have a look at it.he knows skylines inside out.

also TO4GTR had the same problem.it turned out to be a fouling injector.

does the emanage have a hand controller so that you can check duty cycle/overall performance of the injectors? this could bring to light a problem in that area,if there is one.as per dave's injector problem you learn from it.

here are a few possible areas that it could be.

*coil packs.

*coil pack igniter.(if any of the wires leading from the "coil pack igniter" are not giving a reading/or any that are reading spastic on the multimeter.you have a problem.)vise versa for the wires that lead to it from the computer.

*Crank Angle Sensor.(if the computer gets the signal to fire the coil packs at the wrong time you definantly will have a missfire.)

*exposed wires in the ignition system.(that means a thourough check of all the wiring in the ignition system.)

*spark plugs.

*water in the airbox.

*leak in the intercooler to manifold pipework.(the car will spit out black smoke,right after it splutters,if this is the case.)

*afm is a possibility.though dont quote me on that.its only a suggestion.

*the computer.

i've got an idea.

connect the emanage to a laptop and log the data when it is misfiring.

click on the data logger option, which is the one ive circles in RED.

make sure you choose all maps by clicking the button ive circles in ORANGE and choosing the same ones i have chosen then click OK.

to start logging click on start (derr) which is in GREEN.

choose to save the logged data then put it into a .zip file then PM it to me.

ill have a look at it and see if i can help you with anything.

hey guys I appreciate the help but I just got off the phone to Brett (midnight performance) and he has 110% identified the problem which is the fuel pump and fuel pump wiring - why am I not surprised the guy knows his stuff... he has a 32 GTR and R33 GTST S2 himself. I got referred to him by Minh (DR GTR) and once I got to his workshop I realised I know him and hes a top bloke, he helped me out before too back in the r32 days so I was 100% confident that the car will be fixed in no time.

Anyways, I will now tear Dynotune a new ahole =)
