HELP!! i have only had a HKS induction kit and a buddyclub spec III exhaust (not the front cat ) put on my classic scooby (my99) and its broke!!! it feels like the turbo now does not want to work and at 3.5 thou rpm upwards it stutters and lacks power big time!! do i need to take the induction kit off or can it be tweaked to work and if so!! by who?? i have been told many things about them messing up the MAF sensor, is this true?? and I have also been told that the O2 sensor may be at fault. who and what am i supposed to believe. and lastly who can i get help from in cardiff area???
please help me get back on the road. http://www.s-o-r.co.uk/images/smilies/character0023.gif

Put money on its your Maf sensor. To test your maf start engine then unplug the maf. the engine should die.

tried that and it does die, so i presumed the sensor was working ok?? do you know anyone that uses this induction kit or is it a no no. what do i do next?? help please

don't use jap induction kits
specially on 99-00 scoobs
if you really have to have 1 then the best is the K+N57i and 1 of the cheapest . . but unless your looking at 330+ bhp then stick with a panel filter .
swindon isn't far from cardiff , try bob rawle for a decent remap.

BTW i agree with graham, definately sounds like the MAF is buggered
Agree with Daz induction kits are for big power...Best stick with airbox.
Does the car still rev to max when slowly using throttle... Or is it full throttle and stop at 3500-4000rpm..This sounds like overboost. I would put the airbox back on you gain no horses with the induction kit.
When fitting Induction the air flow differantly so the car should really be mapped to account for this.

engine behaves normally until 3500 rpm, with either hard orlight throttle. it gets jerky after that and is more exaggerated the harder i press the throttle.
on the issue of the maf, if i unplug it and the car dies then it is ok is it??

do u have a boost guage? interested to see what boost you are showing?

Yes mate.
I think Bob may be on to something. Boost cut.

nope, havent got a boost gauge yet!! its on the shopping list, but then so is a million other things too, (i dont thikn i am going to be rich now i have a scooby!!)
am gonna put the old airbox back on and see, will just get a panel filter instead, shame really . it looks so nice under my bonnet. just hope my maf sensor is still ok after the induction kit.
thanks guys for your advice, appreciate it.
Some induction kits run ok on the scoobs but most don't and require mapping. Would not be surprised if the MAF has been shaken to peices... My MAF went on 2 day of an induction kit..MY99's are not the best of MAF's to have..
The MAF does not always cut the engine when disconnected. It could be reading wrong at a differant airflow..

now you got me worried!!! well the blinkin shop can buy me a new maf sensor seeing as they installed it!!
hope i get this sorted before japfest!! what panel filter is best for my very tempermental little darling my99??
I always used the Green cotton filter...
If this induction was fitted by a garage/shop tell them its causing problems and to put it back as it was...
With just a center section and backbox I would not expect overboost. As the induction has just been fitted It leads me to believe the MAF is now causing problems...MY99 MAF's are know to give problems and with an induction kit that just helps it along...

what i was thinking was, when you or who fitted the induction kit, if they might have put a hand on the pipe between the turbo and boost controller. disconnecting it, without realising.
be worth checking.

ahh boost controller. will suggest it to the garage. gonna go down in the morning and sort this out properly. cheers for the advice!!

Can't go wrong with a Green cotton filter as Bob says.
Good luck getting it fixed
i bet you have left the pipe that goes from solonoid to airbox off

Its not the induction kit, its the way its bolted to the car.
The standard airbox uses rubber mountings to absorb the vibration.
An induction kit usually has a metal bracket which is bolted somewhere on the body.
This absorbs nothing and as the inlet pipework cannot move the vibration moves on to the maf wire.
MY99/00 mafs are very thin compared to earlier ones, so do break more often anyway.
The fix is to lose the bracket and fix it down with cable ties.
This will allow the induction pipework to move, so soaking up the vibration, before it gets to the maf wire.
I've had a Blitz (very similar to HKS) on mine for 3 years or so, with no problems. It was on it when I bought it and at that stage it was unmapped.
It could also be a sparkplug. The symptoms you describe are not unlike what happened to my car on a track day. Changing the plugs cured it instantly.
Is it hesitating alot or are they single big ones?
It will only be boost cut if your getting one big loss of power and then it comes back. When it happens do you nearly hit the windscreen? Thats fuel-cut. If its like having Kangaroo petrol, then its probably something like plugs, leads, coilpack, fuel pump.
Is it trying to accelerate when you put your foot down? Or does it just get noisier without going any faster?
If its trying then any of the above advise could be relevant. If its not, then you probably have a hose off somewhere.
Just to add:
If you put your foot flat on the floor will it drive normally up to 3.5k revs? And then it starts to stutter?
If so that would again point to plugs leads or coil. You could take the plugs out and reduce the gap to about 6mm, if this improves things then get new plugs.

thanks to you all, have learnt loads off you. took it back to the garage and they replaced the original box but it still did the big jumping thing under power. and the garage said.....oh will have to make a few phone calls. (not very inspiring)!!
took it to hyline in cardiff for a second opinion.. . . they were brill. did a diagnostic and took it out , repaced the maf in minutes and all is fine now !!! they were very good and will recommend them anytime!!

Anyone know why an induction kit kills the maf and the standard airbox doesn't?
My previous post states what I think but it seems people are still set on badmouthing induction kits when its quite obviously the maf that is the problem.
So if we can figure out what it is about an induction kit that changes things, and cure it, we can all fit one without fear.
Any theories?
Not just the MAF Olly M8... I had mine hung on straps but it still went after 2 days... Paul has had no end of trouble with his hard pull aways.
We have also seen a few induction kits causing det on the Rolling Roads as the air is sucked in it vortex'es missing the MAF wire. Airbox straight back on and problem sorted. When an induction kit is fitted and ECU mapped it seems to be ok on fueling.

Ok the det bit is a seperate issue so we'll come back to that.
If the mafs go anyway why is its failure always attributed to an induction kit?
Group N rally cars were maf based and they didn't keep failing. I don't know which type of maf was used though.
I think the best advise would be to save up and lose the maf with different management.:cool:
Do the rally cars not run Motec? Most the lads at CC who race do away with the MAF's they are just to much trouble. See Paul is doing the same.. IT seems to me the MY99 are the weak ones some peeps put induction kits on earlier or later models with no problem. But the amount of MAF failures on the MY99 with induction kits are soaring.

The group N rally cars are much more standard I think.
So stay away from MY99/00 is the best advise.

The MY99-00 Type R's were known to be the best....:hysterical: Pity about the MAF's.
Bob Rawle has been working for some time on a convertion for a new age MAF to fit the MY99 model.

Change ECU to Ultronic,Gems,motec and induction will be fine.

These ECU's on not use the MAF but use MAP thats why I could remove my MAF and give to you....:wink:

stay away from 99-00 ????????????????????
i've had a K+N57i on mine for 18 months and only had 1 maf go , that was on a remap
the blitz i had on before buggered 3 in 3 months , so i asked bob rawle for advice and he told me to bin the blitz and get the K+N which i did :)
olly is totally correct about the vibration btw
maybe the bracket on the K+N is just more secure
