Hi guys...

iam very sorry for my English at first ... But trying to :buffer it :)

Some weeks ago i made the conversion to the LE5 Manifold ( ahhh i have the 120 Amp cheers.. )

Everything sound good and the Power is available!

But after pressing the padle, stop pressing and fast pressing again the accelerator the engine is "Stuttering"??? "stutter" ??? "splutter" i don´t know the word notsure.gif

It feels like the engine gets of for a fraction of a second...

The cruise control dosn´t work very well at all... Doesn´t start very good and i Can not accelerate with it.... When i press the button the Cruise control gets off...

I realy tried to use the search button bit did not found a answer dunno..

Can you please help me :oops: And explain it for me??? THANKS A LOT TO YOU ALL!!!!!

Re: Stuttering after fast accelerate,cruise control doesn´t

it might be the map sensor not reacting fast enough, but did you allow the ecu to reset after fitting the 2.4 manifold and then drive carefully for 75Km dunno..

Re: Stuttering after fast accelerate,cruise control doesn´t

Iam sorry but how can i reset my ECU?

Carfully hmmm 10-15 km i think.... :wtf:


What a thought...

TB damage?
Fuel preasure?
Dirty injectors?
Bad contact to the injectors?

The plastic tunnel before the TB ... there is a sensor... For what is this sensor?

Thanks a lot again! Greetings Marc

disconnect the battery for 20 minutes will reset the ecu, drive carefully for a while and the ecu will learn the new parameteres required for the 2.4 manifold

the plastic tunnel sensor is the air temperature sensor

Re: Stuttering after fast accelerate,cruise control doesn´t

I tried it...

But it didn´t work :(

Yesterday i pushed my Car very hard from first to second and third and then liftet the pedal... after lifting it the engine stuttered...

Not during the acceleration only when I want to hold the speed or when i want to get slower...

Can it be the AGR?

I bought a "blind" plate for the engine and the AGR is "in the Air" next to the Engine... Is a AGR Cheater better?! dunno..

Re: Stuttering after fast accelerate,cruise control doesn´t

might be worth trying a spare coilpack dunno..

Re: Stuttering after fast accelerate,cruise control doesn´t

iam very sorry ...

but what is a spare coilpack?

I thought that it has something to do with the petrol pressure??? Something wrong with the injection bar or the petrol pressure regulator? :?

Re: Stuttering after fast accelerate,cruise control doesn´t

what I meant was borrow another coilpack from someone

it could be a bad connection on one of the injectors, might be worth checking

On monday i will check all connections of the injectors :) Thanks :)

I tried many translator websites ... but what is a ??? coilpack ???

coilpack is the black thing which covers the spark plugs, sometimes referred to as the coil or coil pack

THANKS A LOT FOR THE GREAT DESCRIPTION!!!

So you thing may be a new or 4 new coil packs will help?

Tomorrow I will remove the hole 2.4 and check it :)

Thanks a lot again!

Got the same Problem.

Is it possible to check if the Map-Sensor is working properly?

Re: Stuttering after fast accelerate,cruise control doesn´t

So yesterday i finaly removed the 2.4 manifold and filled the gasget between the 2+3 port with Silicone ( 300 cel. )...

in a cuple of minutes iam going to install everything again... hopefully it will now work without a little stutterer / dip at around 2.000 rpm... cryb..

Re: FOUND IT!Stuttering at 2000 rpm, cruise control doesn´t

two days ago i removed everything again for the "TÜV"... here in Germany every Car must be TÜV proved every 2 Years...

I fitted the old Manifold... BUT i did not found the EGR tube... :upyours:

so... original Manifold out... and the 2.4 again in... :LOL:

after fitted everything a drove a litte bit... cruise controle dosn´t work... :evil:

Vocky told me that it can be the coilpack... i checked them... they were OK! hmmm

I thought but maybe Vocky is right and something is not ok with the fule preasure...

So I organized a new petrol pressure regulator ...

and now the Cuise controle is working perfekt!!!! And no more stuttering at 2.000 rpm!!!

Thanks all guys for your help!!!! cheers..
