OK guys we can rule out intercooler pipes blowing open under presure as these were all removed and doubble checked yesterday..... Still haven't done 02 sensor or fuel reg yet, hopefully these will be done today but i am at the mercy of the mechanic who just happens to be my girly's old man and for some reason like doing paying jobs more????????

money still on BOV

undo the ricirc pipe block it off and then cover the snout of the BOV with lots of duct tape so it will not leak. go for a drive and see if the car is still doing it

I had similar problems a while back, it turned out to be the idle control valve thing under the throttle body (I cant remember the name correctly) but I pulled that out and replaced it and bam! all my problems went away and fuel economy returned. This was of course after I checked just about everything else... - I think thats what 1400r and JVP-R32 are talking about.

Check ecu to see if it's in safe mode.... altho maybe not cos you can actually drive it. Worth a look at the led tho

iac motor is on the throttle body.

aac valve is at the back of the plenum.

cant remember exactly what nissan did, but it worked.

[Rekin]

Had similar Probs with my r32.

My aac valve was blocked and caused idle hunting and a real bad grumbling sound when car reved and fell back down to idle.

Check O2 sensor as Paul advised.

ok here is an update.... It has been worked out today that one of the temperature sensors was giving a dud reading because of a caroded terminal, so we are replacing some of the damaged terminals and cleaning up some of the others. That has apparently fixed the dud idle!!! Horay for that as it has been like that for nearly a year...... But as for the power and turbo problems!!! that has been tracked down to the waste gate opening early hence the lag but the turbo sounded like it was spooling fine. Now for my next question...... Would this be a buggered actuator? or i believe there is a spring that pulls the wastegate into the closed position? is that kinda right or am i just tripping.

Thanks again for all the help guys!

I'VE HAD A LEAK IN MY INTERCOOLER FOR ROUGHLY 4 MONTHS NOW(WONT EVEN HANDLE 7PSI)AND IVE HAD NO PROBLEMS WITH STALLING OR ANYTHING LIKE THAT!! ID LIKE TO KNOW HOW MANY PEOPLE IN HERE ACTUALLY HAVE ANY MECHANICAL SKILLS.

You 'accidently' pressed your caps lock.

You will find people don't read all caps posts as they are difficult to follow.

thats there loss

Block the wastegate shut and take it for a test drive, keep an eye on the boost meter though. Dont want it to go boom!

If you read one post up he says the stalling prob is solved, it was caused by a caroded terminal on the temp sensor...

Yeah thanks thats what we are going to do.... dont have a boost guage other than the factory one though. Should probably invest in one. But yes i dont intend on testing anything to the fullest so i will be keeping a very close eye on how far i actually push!!!! im thinking keeping hard acceleration below about 3500 4000 rpm should be enough to tell me all i need to know and hopefully keep boost at sane levels. Factory boost cut should still be in place as far as i know unless it was removed previously in japan. I aim not to test this though.....

Lets hope you havn't glazed the bores by having a IC leak.

If you've had a IC leak for 4 months then you clearly don't have any. LMAO!!!

when one of the cooler pipes close to the turbo outlet ( the first join after the elbow) blew completely off in an r32 i was doing an intercooler install on, the car ran fine but stalled when coming to idle. if you held it at 1100 it would run. there was a good 10/20mm gap between the 2 pipes at the closest point, but they were still facing each other. the turbo was basically "fanning" the unmetered intake.

in less extreme cases, if some boost is lost in the cooler pipes then it has already been metered and fueled for, so you are always going to be too rich for the actual air in the cylinders.

Hey guys, after scanning some of the other threads some people think that cleaning the injectors could be a good idea for fixing idle issues???? Any one got any thoughts on this??? Also how much would it cost roughly to get the injectors cleaned???? Could be an idea to do them anyway cause they certainly haven't been done since the car has been in australia running on our sh$%ty fuel!!!!

[sanger]

Anyone??

[JVP]

just get them cleaned anyways mate, might be a good idea for in the long run...
