Gtr Running Rough As After Engine Detail?

[Ashy Larry]

That's the one, thanks Bubba

Vacuum hoses were my down fall

[bubba]

Yeah I had a troublesome one that kept popping off and making the car run like shiet!

Went right over the car last night and found a plug that was unhooed between dipstick and oil filter so I am hoping that might have something to do with it, I also found a lot of moisture in various plug connections so have dired them all out + I have pulled the afms out and will resolder the connections today!

Cant seem to work out which vacume hoses you guys are talking about? In and around FPR?

Thanks,

Dan

Different car, mine was up the back under the throttlebody (gtst plenum).

[Ashy Larry]

Yeah mate up the front near the FPR and there is a little electrical connector near the hose I am talking about.

i dont really wash my engine bay as i dont want to risk getting water into my coilpacks so what i usually do is wipe it down with a cloth but if you have to wash the engine bay, avoid the top part of the engine. i even had to tell the mechanics not to wash an rb motor with degreaser and pressure cleaner cause we had one who made a mistake of doing that and the car was misfiring badly and he had to take the coilpacks out again and blow dry them and the car ran fine afterthat. you can wash and degrease underneath the car or on the oil filter (which is away from the coilpacks) but avoid the cam and coilpack covers at all cost.

UPDATE: Still running rough- poor idle / Blowing white smoke / loss of boost / power

I have spent all day again going over everything

- solderd up afms again (the car is definitely running smoother but no boost/power and a lot of white smoke)

- checked vacume hoses

- checked electrical connectors and checked for exposed wiring

- Pulled apart BOVS (these were caked with fuel especially in the alloy elbow connector? Can this happen from to rich a mix? Normal?

(Boost gauge 'standard' still reading 0)

- should I get out the multimeter and start checking everythings getting power

- I have got a nissan consult cable and software but no working laptop, would it be worth borrowing one if its likely to pick up such error codes that are affecting car

Would it be worth taking my coilpacks out again and checking for moisture as i only gave these a quick wipe as i couldnt see any moisture on them- only down in the spark plug area where water was sitting?

Ok I am really stumped now so I'm going to mention everything i have done in the past weeks!

Changed my Pods over the other day from Hks mushy pods to some M's pods, i wouldnt need to reset my ecu for this would I? Running a BLITZ ACCESS ECU

Having my fuel pumped earthed at the moment meaning the pump continuously engaged- is it possible my injectors could be over-firing or somethings a miss with the FPR?

Thanks again for all the replys

I pulled all the connectors out around this area aswell as plenum sensor thing but there wasnt a vacume hose? Not the one half-way down the intake plenum that connects into the head?

while u got the plugs out, do a quick check of compression

=] my rb had similar symptons as what your saying mate... wasnt lumpy but had smoke and that

cyc #6 was down a little.. i keep driving for a few days and noticed more whitey smoke

i mean the power was still there, until the last day when i decided to take it off the road.. coz i actually had oil blow back

and was running lumpy.

was my ring land had broke, melted to the top of the piston lol and most of came off during last day...

all due to running lean

Had my compression checked at workshop probably 100km ago and it came back perfectly consistent 150s!

Do you mean just with a handheld compression tester gauge? I havnt used one of them before but will see if I can go pick myself up one tommorow!

I am still convinced its something ive done whilst cleaning engine as the car has barelly been driven 100km in the last year and a half and had been running perfectly before clean?

Wet solenoid?

Wet solenoid?

Checked boost solenoid tonight but all normal there!
