first of all welcome to sidc,

i gather you gave the car a real good look over before buying it as its not always adviseable to give it the beans without noing a great deal about it?

however this site iput up should give you all the answers youneed, your car has a on bord diagnostic check under your drivers console

hope this helps

Checked all the hoses? Might have popped something if you've overboosted.

Is the car mapped to UK petrol? Run on v-power or another premium product?

Yes checked hoses as much as i can see,

I was just out of petrol station always use v-power.

Hose was my first thought but cant see anything obvious (but when is it ever)

Car was running sweet as till 3 hours ago, not a sign of smoke not a rattle anything that would suggest it was abused.

I did try to decipher the code to no avail, but it was flashing lots!!

Cheers again

ok mate you need to study this web page to learn the codes it took me a while, this could be your maf, if thats the case the flash code would appear a bit like this

long

long

short

short

short

long = 10

short = 1

this code exsample = 23

the codes are read by connecting the black connector

you can reset the code by doing the green connectors but will only wipe the codes till next time, wont solve the problem untill the nececerys are replaced/fixed

cheers

Is it possible to get car connected to a fault reader for easier diagnosis?

Flash sequence seemed a lot more than this mate but couldn't get my head around the it maybe tomorrow when a bit less pissed off i will get it better.

Cheers

might want to post where about you stay mate that way people will know if there close enough to offer assistance.

It sounds like your car has gone into limp home mode. The car will appear to idol fine whoever if you try and give it beans and hit boost you will feel like someone has just put a brick wall in front of you. this is supposed to happen to protect the car. no higher than 2500 rpm till you get the code worked out.

and the maf in the 99/00 cars is an extremly common fault due to its design. i'm on my 3rd in 18 months (fitted the new one earlier tonight)

you could try resetting the ecu and then take it a drive. if the cel comes back on then get it to a dealer or see if anyone near you can help you read the fault code.

just readin this, 1st post says car will NOT idle and runs like a bag of nails.

if ecu went into safe mode would still idle and drive, just have no guts.

sounds like it could be expensive, did you let the car warm up before flooring it?

:rolleyes:

would deffo say something mechanical in the engine rather than boost pipes off.

Someone else posted today about a mech fault!

where abouts are you fella, i'm in the falkirk area if you're anywhere near I'd be happy to have a look for you.

Hi,

Id reset the ecu to start with. if its the maf then the code will more than likely come back i would think.

My car did something odd like this once, afterwards it would not idle well at all. Turned out the idle control valve had stuck for a bit. After pulling over and turning the car off and then on again it ran rough then cleared.

The stored code was ICV.

Is it worth giving the ICV a wee light carress with something?.

i.e tap it with yer knuckle.

Best of luck.
