Its ok...

Mine does it too.....

I have a splash panel to fit asap as it can be annoying but its never cut out completely...just misfires.

only way is to poodle about so that should be quite easy in a red zed :slap: :rofl:

Phew it's not just mine thats been messing about ! First time it's really rained since I fitted it - not a good sign for the winter !

 

I was reading another thread that seemed to suggest the PTU could be responsible and I was thinking 'sh*t more money out the window !'

ye. on the way back from jae during that rain mine kept on juddering.

 

I noticed several months ago after fitting the scarab bumper. but i dont have an air filter at the moment so that wont help.

spray going in your large bumper wont help m8

also the headlight panel openings and the seal round the panel

i ended up fitting twin apexis pointing upwards to cure mine

and properly sealing the headlight panel

If its the foam ellement filter, when I used to do motocross they do a can off stuff that you soak the foam elements in to repell the water. and you can wash them out after!

its moisture getting on the AFM ........i had it when i fitted my blitz sonic induction ,

but when i fitted the 99 spec front end it stopped playing up even in heavy rain ??..

 

I Did stop it before by using a pir of my wifes old tights over the induction intake and fastened securely , they act as a filter fine enough to catch and repel most of the bigger droplets of water and road crud HTH

I had exactly the same problem. Mine was fine driving in the rain but if left to stand on the drive way during heavy rain then it would play up for the next day or two. It would play up to the extend that it was undrivable but it was noticably less lively after heavy rain.

 

I did a bit of research using the garden hose and found that the problem was that the nose panel doesn't seal well enough to prevent water dripping onto the filter.

 

I believe that this is not a failing of the nose panel. Looking at the original airbox it is designed so that it doesn't matter if it gets wet from above. Therefore I don't think the nose panel was ever designed to be totally water tight.

 

I solved the problem using thin sheet plastic. I actualy got mine from the spines of A4 and B5 files. Using zip ties and the bolts for securing the A'pex-i filter I engineered a cover that sits above the air-filter but below the nose panel.

 

It's hard to explain without pictures, but I worked out that water was getting in at both the top and the bottom edge of the nose panel. Water entering at the bottom (where it meets the bumper) would gradually drip straight onto the top of the filter. Water entering at the top edge (where is meets the bonnet) would drip onto the piping above the MAF, run underneath and down the the underside of the airfiler.

 

I used two sheets of plastic, one from an A4 notebook, one from a B5 notebook ensuring that any water coming through the panel could not get onto the filter.

 

In addition, I used the spay feature of the hose to direct water in through the front of the bumper to simulate heavy rain whilst driving. I noticed that some water was making it's way around the original water shield and onto the filter. I used another A4 notebook cover to extend the original shield curving it upwards to further protect the filter.

 

After restarting the ECU needed about a week to settle down. I expect I've seriously altered the air-flow around the filter. Once settled though even in the heavest of rain it all seems good! It does seem to have altered the induction sound slightly, but not in a bad way.

 

I know that pictures would be beneficial here so I'll try to get some taken for you all.

Should say "it wouldn't play up to the extent it was undrivable ..."

 

Sorry - can't type this early in the morning :confused:

I did exactly the same as Rory , made a panel to stop water getting on top of the filter, it was dripping inbetween the bumper and nose panel , iv.e not had a problem since :hyper:
