persisting problem !

[bigdavie]

right i had a prob the other day and you guys correctly diagnosed a maf fault cheers !!

today the problem is back the power is surging if you know what i mean ?? when you floor it its like im rolling the power on and off but i'm not ??

i dont think its the maf this time as the car is now idling properly !

any ideas folks ?? this is starting to worry me

cheers

Bad batch of gogojuice perhaps?

If you're at the meet tonight get some of the mad scientists to have a look.

[bigdavie]

aye i'll maybe keek my heid in for a wee while and ask a few bods to have a look at her !!

[colin_ross]

Could be a few things. Do you have a boost gauge and is the boost stable? It's quite common to fry the lamda sensor when the maf goes. Have you done an ecu reset to see if it throws up a cel?

[AVI_8]

Have you replaced the MAF yet?

My car is doing the same thing boost comes on and off, apart from that it drives perfectly and idles very evenly.

I was told that the problem sounded like a failing MAF. When I unplugged the MAF with the engine running the idle dropped a few hundred rpm and then recovered, if it was working ok i'm led to believe that it should have cut out by unplugging it. Im getting a new one asap but in the meantime driving off boost.

So it would appear that they dont always idle unevenly with a fcked MAF

[bigdavie]

yep replaced maf  /dont have a boost gauge and i just disconnected the battery to reset the ecu ?? is that ok ??

[colin_ross]

That's how I do mine, couple of hours should do it.

 

[AVI_8]

I'm sure i've read somewhere that the battery will have to be disconnected for several hours in order to reset the ecu.

Apologies if i'm talking bollocks

[bigdavie]

ahh !!!!

i only let min rest for a few minutes lol !! can i get confirmation of this ??

[AVI_8]

Try a search on this site or scoobynet

And theres a website called www.saxonfields.freeserve.co.uk, I'm sure theres a link on ecu resets there.

[Jazmac]

15mins should reset the ECU.

A friend of mine had the same problem and had everything looked at and

in the end it turned out he needed a new set of plug leads belive it or

not!

[bigdavie]

problem solved !!!!

it was the boost solenoid needed cleaning !!

exactly as ally b had suggested !cheers buddie !! took it down to greers and they told me the same as ally you cant top the 99 00 cars up to the brim with oil as it fudges the solenoid !!

so a big thanks to ally and a big thanks to greers again !! brilliant !!!!

Thanks for the thanks Davie .[:$]

I'm no expert , but I've owned a '99 and a '00 so I know most of the things to look out for with them []

I'm glad my diagnosis was correct and maybe saved you a few quid.

Scottish-scoobies guys are generally a good bunch , and we all try to help each other out with the benefit of our own hard-earned lessons .

We all know a little , which put together is a  LOT of knowledge  .

Good to see you last night at the Glasgow meet and I hope we'll see you again at the meets [Y]

ATB,

Al.

 

 

[bigdavie]
