Rough Idle And Turbo Cutting Out

[PM-R33]

obviously you dont know much better than me if your post sounds just like mine...wen u mention AFM problem??!....you need to relax !! if you kno more than a professional import mechanic i apologise.. if you dont maybe you should get off ur hi- horse and chill. Dude y would he freak out geezzzz ... I just wanted to suggest he get his tuner to check it out first rather than him spending $ on uneeded shit...and then then you start having a cry ...

Seriously are you like 16 years old? You are not txting your boyfriend so type proper english FFS.

An afm failing will show similar symptoms of what he described. As will a number of other things including those allready mentioned. Do you even know how an AFM works? Without physically seeing a car and knowing all the details it is semi guess work trying to give advice. Hence why I also seperately asked about the smoke out of the exhaust. Would give more clues without physically seeing the car.

You make it seem like every mechanic is an expert. Sorry but no. I would take advice from the forum before taking the advice of most mechanics. Given that there are only a handful of speciality Skyline mechanics in Australia that actually know their stuff and most are on these forums anyway. Given that he has a stock ECU I doubt he has his own tuner.

Who said he was going to spend money? He asked for advice, not "what do I need to buy?". Swapping over an AFM with some one elses is a 5 minute job and doesn't cost you a cent. Checking the BOV also doesn't cost you a cent and takes 5 minutes.

you say "This type of attitude on here will not get you far" ....ahahhaahahhahahahahhahaaha thats priceless dunno wat in helll u mean by this but maybe your just having a BAD DAY..i think you have the attitude issue mate i love my skyline and respect all nissan fans ... thats my attitude!!!!

BOOOOOMMMM!!! ......n yehh its like that!!! maybe this will cheer you up a bit aahaha

You act like a child, appear to be unintelligent, have a stupid user name, have been on the forums for less than a month, are starting shit with some one that has been on here and knows about Skylines a hell of a lot more than you and start mentioning forum users as e-mechanics when most of them on here are proper import mechanics, engineers (like myself), tuners or just highly motivated car lovers that enjoy doing every thing them selves.

It is YOU that needs to chill and get off his high horse. Your the one that arked up because I called you on your lack of knowledge of what an 02 sensor does. Get over it and grow up.

Yes, black smoke coming out of the exhaust when having the idle issue. I have a stock bov i can swapover so I'm going to do that today. Will post results.

[PM-R33]

Righteo well that definetely points towards an intake leak.

While the car is idling just put your fingers around the blow off valve and you should be able to feel the leak. For the idle to jump up and down as much as it is it should be fairly easy to feel the leak.

Im not a engineer like yourself but am highly motivated car lover Ive had my skyline for 6years now and ive done alot to it myself so im not stupid as you are suggesting i am...iv used many tutorials that have been a great help in replacing afm,break pads, oil and oil filter,bov, pod enclosure, battery, boost gauge, stereo, vacumme lines etc. My tuner is great mate he owns a turbo and dyno shop in brisbane so I am 100% He would kno his shit and could find the problem straight up. Thats what i meant by "pro"...i never mentioned a normal mechanic would do. Its great when the help you ask for works but when it backfires you can only blame yourself for taking advice from a complete stranger.

Dont make this personal and start taking chips out of me ...Seems you got urself offended by taking things out of context. Im over trying to explain myself.

next time if you got nothing positive to say about someone dont.... and LOL at urself for spinning up a tornado out of a fart...

Fixed!

Fitted the stock bov, made no difference.

Checked the hose clamps on the intercooler piping they were a bit loose so tightened and solved the prob.

Cheers for all the advice.

[PM-R33]

There you go. Simple vacuum leak that you fixed yourself. Didn't need to take it to some "pro" mechanic.

[bteng]

OK so thought I had fixed it but after driving for about 20 mins the same thing happened and its back to the rough idling, not sure if tightening that was a coincidence or not now.

I guess next test will be swapping the afm. Can i test using one from an R34?

get a consult cable before you go replacing sensors, it will tell you if they are dead most the time, most tuners should have one and I'm sure they would happily plug it and run a scan in for a small fee if you asked.

well i was just going to swap one from an r34 to test if it fixes the issue

some others mentioned testing for vacuum leaks whats the best way to go about this?

[GODZILLA-GTR]

are u sure the same clamp hasn't just come loose again? water and some soapy water in a spray bottle for boost leak hunting

yeah i thought that as well one of the clamps looks a bit dodgy but i re-tightened it to no effect

ima try the soapy water now cheers

You should be able to feel and hear any sort of vacuum leak so just stick your head in the engine bay and have a good listen and use your fingers to feel the suction if you are suspicious of an area.

Yeah when it starts the wavering idle I can hear a tshhh tshhh sound in time with the revs but cant pinpoint it. I'll give it another go tomorrow.

I have the same problem with my r33 s2 recently except my ones worse. I check the hose and clamps everything is tightened and im guessing my turbo is blown what do i have to do????

[bteng]

So in the end I had to replace the o2 sensor and the afm all's good now.
