Hey guys, long time no post...

I'm trying to smooth out the idle on my 535. I read about increasing the spark plug gap. The stock is .028 and it suggests .034-.036. I put my stock Bosch's at .032. Don't know if that helped at all but...

I also read a thread here that someone cleaned their MAF and it improved their idle. Does anyone know if that helps? Is there detailed instructions how to clean it? Do you need to remove it? Oh, one other thing... where is the MAF

TIA
