Actually don't know. Havn't checked since I bought the car, the plugs were brand new then. Will check tonight or this weekend. Temp grade 6 is standard, right? With my mods which I've already listed above, should I go for 6 or 7?
Yeah, you're right, vacuum not boost, sorry. I find both the technical issues and the language quite hard you see...
The rpm stays quite even at idle, but not as even as it should be I guess. It "huffs and puffs" quite much at idle, and it's no difference between hot or cold engine. Sounds as your friends R32 had the same probs as mine. Will check the air regulator. One question though; where's the air regulator and how do I check it?
In what way might the bov be the thief in this drama?
What I've heard before the stock ECU would cope with the mods I've done already (pod filter, fmic, cat-back, ssqv)? Do you have other experiences? If it is what you say, then a new ECU is the only solution I guess..?
How do I check the AFM? Already pulled out the AFM cable when engine at idle and it started to run really bad, almost died. That means the AFM works, at least a little bit? Can I clean the AFM somehow?
Thanks for your feedback! Will have to bring a lot of swedish girls to compensate!
