Hi guys!

So I've finally found time to change the plugs. My weapon of choice were NGK BKR6EK. Few unpleasant surprises were expecting me. I started from 1st cylinder. Spark plug that was there was so loose I can unscrew it by hand holding the spark plug extension socket. It was dumping in black thick oil and was heavily carbonized. I wiped the spark plug hole out with clean cloth to suck the oil. Spark plug itself was Czech make Brisk, Premium line. I will post some pictures tomorrow. I am not sure if it was even supposed to be in this engine. Second cylinder, same song. Third was so tight and dry I had problems getting her out. Thread was rusty and plug heavily carbonized. Fourth loose again, dumping in oil. Fifth more tighter than third, more rusty, carbonized and dry. Sixth, the most loose, most oily and carbonized. I fitted new ones. Used a bit of oil to thread on third and fifth to get them smoothly in. Tightened the with torque wrench to 5ONm. And started up the engine. I swear I never heard it running so smooth and calm at idle. Beautiful transition from idle to higher RPM. I noticed slower engine warmup than usual. I plugged the MAF back. Idle OK. But when pushing throttle I felt like slowered reaction between throttle move and engine acceleration. A hesitation. Like mixture was for a moment too lean. But no more intake shooting. I'll try to borrow a MAF from junkyard and try it instead of mine. Any other clues what might be causing this? Thanks again, guys.
