anyone know why my car might struggle at 5000plus revs in every gear???

 

lower down seems ok now!

So no one got any more ideas then?

 

 

seriously though mate, take everyones advice and before u spend another penny take it to a zed specialist and get them to give it a service, i know how it is u dont want to spend any money on anything other than modifying it, but u really need to get the engine reliable first otherwise youll just do more damage.

what i mean is instead of paying loads to buy a datascan/conzult spend that money on a service. conzult will only tell u whats wrong, not fix it. u could get a garage to tell u whats wrong for free.

just wait and see what your conzult check fetches up first, then fix whatever is wrong

The thing is ive changed everything apart from the oil which is pretty much a service, if a garage could tell me what was wrong id be laughing mate but noone knows and are just saying get it on a computer which is why i am buying a datascan.

And im buying one because it the same price just to get nissan to put it on their computer.

Thanks hopefully what i will do. i have jut bought then datascan now!

good work bud :D

Did'nt you say your dumpvalves were releasing at high revs ? That would explain the problem

good work bud :D

 

 

Only cos you want to use it :x:

 

If it works ok you can be the first user, and i owe you one anyway mate so there won't be a charge to you, if you want to know why i owe you one pm me, same with cadpaul and mujina

Yes i did mate but s ince had them adjusted to 3mm and seem to be ok now, maybe they need to be 1 or 2 then, anyone know?

have a good look for boost leaks under pressure. can you rev the engine above 5500 with light throttle?i fyou can then prob is a boost leak on the pressur side . i fyou cant still rev the engine on light throttle look for poor connections etc . Wouldnt think a service will cure this you need to fix the problem then think about servicing .

well i do ned some injector connectors mate! the car does go above 5/5500 revs but starts to struggle around this time

loo for a high pressure air leak . can you rev the engine under no load ?

i drove it the other day and it didnt seem to have a lot of power, gave it a short blast but noticed that when i pulled up and revved it it wouldnt rev properly (as if only running on a few cylinders)

I think so, ill have to have a go tomorrow now though but any with boost i can rev it but it then starts to struggle picking up the pace, maybe it is the injectors

Oh, i forgot to tell you that we found one of the big problems!

You know the 4 big turbo pipe thingies, well one of them wasn't on properly so most likely thats why it was sometimes cutting out and also a big leak :dance:

could be the conection's on the injectors . pull them off and have a check a good tip is to spray them with a good lube oil before trying to pull them and they should come off ok if they are no good then you can buy the connectors with terminals to carry out a good repair if need be.

well i need to buy a set of the injector connector for definate, mine are shot

its a good place to start when the connection's are bad the injector voltage and ground signal are no good so fuel del will be poor plus you can get misfires all over the place .

you can buy the connectors as i said to do the repair . im not aloud to say to much as im not an offcial forum trader .

Are you in trade outside like?

I found somewhere the does the 6 connectors for i think it was about £40 or something, i just hope thats the problem

20years man and boy :) nissan master tech .£40 is a good price . is that for new connectors or second hand old loom repairs?

They are new, look at my previous thread about them!

 

So do you actually work for nissan then?

ok cool . good luck

please clarify, did it happen before the BOV's were fitted, and is it still happening now you fixed the air leak.

Buy a Nova !!

In all honesty i dont know as i hadn't fixed the air leak before the bov's were fitted and it was then struggling all the time but in all honesty i hadn't noticed it as bad before they were fitted
