Gtr Running Rough As After Engine Detail?

[kx2fity]

Hey people am having some dramas with my GTR:

I had a go at cleaning my engine bay the other day as the car has been off the road for the last year +, all went good so I decided to give it a bit better clean today.

I alfoiled up some electrical bits WP40 others and then went about degreasing the left-handside of the engine bay and then spraying scrubing etc

When I started the car up it blew out a lot of what looked like water out the exhaust?

The car idled very rough and when given acceleration sounded very hollow, backing off the acceleration the car would drop to around 300rpm and them slowly and sparatically make ts way back to 1100rpm.

I then took the car for a short drive - it had trouble taking off and then a complete loss of power and started blowing blue smoke - i took it straight back to the shed where i kept it idling for around half an hour or so.

The car kept engaging "clicking" something that would drop idle rpm and then slowly work its way back up to normal rpms!

The car stopped doing this after 20 odd minutes but any time i tried to drive it - would blow blue smoke and loose all power?

(The car hasnt been driven much in the last year but had it running perfectly and took for a decent drive about two weeks ago )

(Also having a small fuel relay issue which means the fuel pump is earthed engaging as soon as ignition is switched; cant see how that could have anything to do with it though???

Any ideas or advice would be greatly appreciated????

Thanks,

Dan

if i remember,

black smoke: running rich

blue smoke : bad turbo

white smoke: burning oil

saying that it might be ya turbo(s)

Hmmmm that could make sense as i know the Bov's wern't venting at all when i was driving!

I am really hoping its electrics so will start with and around turbos!

you could have just got water under the coil pack cover into the spark plugs

Would the engine heat after long idle not evaporate all the moisture in and around the coils and plugs??

Will have a look at this to as I did give it a fair hammering around the coils/plugs!

[Slowpoke]

My guesses are coilpacks or plugs.. so if it was me, i would take them out and let them air overnight and put them back on in the morning..

sometimes even if it is still in the engine, it will end up dry overnight and all will be good again in the morning..

Just my 2 cents

sounds just like when i lost a turb lst week

car making boost past the zero mark?

iv had the same problem b4 after cleaning the engine bay.. it was water sitting on top of the plugs and somehow getting in.. take the packs off and look for water

This has me worried - I don't think it was making boost!

Cheers for the replys,

I am going to take cover off tommorow and do a full inspection and see what I can find!

Well most of these "running rough after washing" threads usually come from water in coils/plugs or afm.

The fact that it is blowing blue smoke is rather worrying.. blue = oil = rings? turbo seals? valve stem seals?

def water in the plugs area just take the coil packs out and use tissue or cloth to drain the water and should be running sweet as:)

Bubba u r correct, Blue = oil = rings. I had the same problem with mine when i gave engine bay a degrease. Took coilpacks and plugs out, got the hairdryer out and dried all ignition parts and was back to normal.

But blue smoke, hmmm not good news!!

I am actually beggining to think it was white smoke now as I only got a peek at it as i was driving along in the rearview!

Im heading down now to check for moisture in and around coils and spark plgs will let know if this fixn her up!

Thanks again for replys!

How long had it been since it was last driven? before you washed it and discovered this problem..

[kx2fity]

Update:

How long had it been since it was last driven? before you washed it and discovered this problem..

Its been about two weeks since I last drove car - of which at that time was running fine!

Have taken out coils and plugs and as predicted the first three plugs were caked with water so have cleaned and dried all plugs / coil packs. The car is definitely sounding better at idle but still has loss of boost/power and blowing a lot of white smoke (not blue as thought before) and spitting oil out the exhaust?

I am a bit stumped now as to what could be still making it blow white smoke and loose power?

I did give it a good blast and scrub around the fuel rail / injectors / Crank angle sensor areas- could any electrics in these areas be causing such an issue?

Another unusual thing i have noticed is the clutch making more noise then usual when engaging ( brand new have driven less then 20km with- twin plate ORC) cant work that one out at all either?

It's likely fuel it's spitting out the exhaust, not oil (lots of fuel will look like black wet shit everywhere).

Check and clean the CAS, along with the AFM's.. my money is on the AFM's got wet, something shorted and now it's in limp mode (I did mention them earlier )

[Ashy Larry]

the hoses on the front of the fuel rail and around the front near the fuel pressure regulator

I had something similar after changing out my injectors... just look closely at all the connections

Yeh that sounds more like it 'fuel' Im just going by the dirty big spat trail i left in the shed of which my old man cracked it and made me degrease it all up haha

I am heading down tonight so will start with the CAS and remove the AFMS and check these ( The reason I didnt think it was the AFMS is because last time i cleaned the engine bay i completely removed these and coles bagged up pipes and the second time i had a crack at cleaning the engine bay i kept completely away from the right handside of the engine bay as to not disturb them but yeh water i guess could have still somehow got in there)

Thanks for your help mate!

Yeh that was my first guess i had disturbed something in this area so will be down there tonight checking all connections and i mite even test the injectors aswell!

[bubba]

Hmm yeah vaccum hoses!
