Help!! car won't come on boost...

[Rskyline33]

appreciated if any could help or have any ideas...

i was cleaning the engine bay 2day, sprayed with degreaser and then with water. i then took it for a drive and as soon as boost hit 0 on the boost gauge the car starts to hop and boost won't go pass 0.

Blowing lots of black smoke? Could be an Intercooler Pipe that has blown off. Other than that seems a bit odd.

did you put any water on electrical system?? like fuse or connectors...

fgive ew hours to dry out...

sounds lilke short circuit problem

i didn't cover anything when i sprayed the water. so this might be the problem..

also when i sprayed stuff on, the car was a little hot.. when i spray water on i can see smokes come out from the bottom, where the turbo sits.. so i think its something to do with the turbo.

Man thats just not smart.... no offence....

As mentioned above, check all your intercooler piping. How is it idleing? Is it popping when on idle?

if it idles real rough, blowing black shitty smoke, or wont go over a certain point - say 2.5-3K

maybe your air flow metre/sensor could be crook/disconnected/not plugged in properly

i dont think spraying water around your exhaust when its hot would damage it to the extent of not being able to make boost (at the most it would only crack the exhaust manifold), my money is on an electrical problem because it has water in it. try unplugging a few things that may have gotten wet and spray them with rp7 to get the water out, but i would think that even with electrical problems it should still make some boost so as boosted_rb26 said check all your plumbing connections, the degreaser may have helped a hose slip off! perhaps!

[goulash]

lol dude you need a turbo or supercharger to get boost

[juso]

coil packs? water in spark plug conecters? get air compressor and blow everything out..

[Rskyline33]

thankxx heaps everi1..

it was the weirdest thing.. the car revs fine, it idles fine. it just won't come on boost...

anyway, i leave the car running for 10mins, 3 hours later took it for a drive and everything's back to normal..

so i still got no idea what was going on in the first place.. could it b because of too much water in the intercooler, because i sprayed i fair bit in there.....oh well, a lesson for every1, don't panic like me, i was getting instructions from this forum on how to remove the turbo... damn, could of gone wit a hi-flow

why the **** would you spray water in your intercooler?

because there's flies and sh.t in it, so i couldn't help it..............

anyway, just when i thought the car's back to normal again. the nex day took it out, it was fine for about 10mins. then it happen again, can't even go pass 2500rpm... surely some1 on here must of seen me on saturday ' a red r33 on tomkin highway moving slower than a donkey'....

so i went and saw a mechanic and found out the real problem.. water got in the engine.."where its got 2500 TWIN CAM NISSAN", somehow water got in there..

its all good now..hopefully... thanks everi1

Sounds like afm problem of some type either plug is a little dodgy or the afm itself is buggered

[Sneeza]

Yeah I had a similar problem after my car got detailed and they OVER detailed my engine bay too :hellpisd: . I would get to boost and it would cough a splutter.

Water got in the AFM and the plugs. I pulled the AFM off and made sure it was dry. The plugs also had water on them - Ken from Hyperdrive told me to leave the car idling for like 10 - 15 or so minutes to dry the plugs out... it made it alot better.... but it took a few days of driving before everything was back to normal.

thats what i tried to say :ufo:

chekck your afm first, before you pay him to do the engine.

thanks man but i didn't hav to pay anything.... i know the guy so i spoke to him and he said to take the plate off and leave it for a couple hours to dry... and i think its working, took it for a long drive 2day and everithing's fine

and Liz could of told me that earlier.. i was all stressed out Friday night and saturday morning... don't know if every1's feeling the same way but my car is like family 2 me, if something happens to it i can't eat n sleep probably...
