OK, so I bought that airbox cover off Ebay, Drilled it just like John Miles says. Got in it today for a first Burn, shoulda seen the smile on my face at 4000 revs and a cherry bomb noise! However, the car has suddenly gone jerky - coincidence or do I have to DME reset?

Also the wife called me a chav because of the noise!

May have to revert to old box and ebay the drilled one!

Advice welcome on jerking problem!

Coincidence I'd have thought. Mine didn't go jerky when drilled.

I'd definitely try a DME reset.

Same here, no problems after drilling... DME relay on its way out?, DME reset needed? Did you disturbed a wire/connection while putting the cover back in its place?? Plug wires bad??

andrew911

what are the symptoms of a DME relay going bad? Is it a "it works or not" type thing, or does it sporatically cut out the motor giving a jerkyness like brooke describes (or a different kind of sputter/jerkey action)?

If the airbox lid is not securely fastened back down this can happen

Mine worked fine after cutting a portion of the airbox cover away.
What's a chav?

It can go either way... It can just shut your car off or cause a host of problems. I always carry a spare just in case. Sometimes if I'm having a problem, I'll swap it out just to see if that is what is causing the issue. It hasn't been the culprit yet... But I still carry it.

I have drilled a lot of air boxes in my day and never had trouble, but I do remember reading on some sites that a rough idle and stumbling can result. I have no idea how. I have run mine with no lid, filter or anything at a auto cross and did not have issues.

Gotta be a coincidence - swapped mine for a Fabspeed cup box and I had no hesitation issues.

On both my 964's I've modded the Air Box cover - on the 1st, I drilled it like John Miles & didn't like the resonance it caused. On the second, like you I bought a spare cover & cut a large square hole in it, just like the cup/fabspeed cover & it sounds great! No resonance! Never had any idle/hesitation side effects from the engine.

I'll pop the old one back on tonight and reset the DME, then report back.

A chav is a word over here which describes your typical hoodlum in a cheap car with a large exhaust pipe, under car neons and a burberry cap.

I also just have the frame left and no problems, no strange sounds...just +25 Hp! :-))

The car was going beautifully before. Typical. If it ain't broke don't fix it as the wise man said!

Chav is a derogatory slang term currently in popular usage throughout England. It refers to a subculture negatively-stereotyped as being uneducated, uncultured and prone to antisocial or immoral behavior. The label is typically (although not exclusively) applied to teenagers and young adults of white working class or lower-middle class origin. Chavs usually wear designer labels, and if they’re girls, very short skirts and stilettos. Chavs still see branded baseball caps (esp.Burberry) as a status symbol and wear them at every opportunity. The word chav is generally thought to come from Chatham girls (Chatham is a town in Kent.) Some people think, however, that the word comes originally from the Romany word chavo (boy), which is also the origin of the Spanish word chaval.

Chavs don't drive Porsches. They prefer 'souped up' shopping trolleys ( e.g. Citroen Saxo, Renault Clio, Vauxhall Corsa)
