yes they are seperate. the new pcv valve helped a little.
the new maf cured a stutter issue we had between 2k and 3k. so im assuming thats good now , drives nice.
still has rev hang. with the vss unplugged the engine jumps all over the place , its better plugged in but maybe it still is not working , does anybody no the part number for this because i cant seem to find one for this car . when i was looking at parts the other day i had stuff listed under mk7 ? it seems theres a few versions of these zetecs some maf some not same as vss.
i think i will try a different vss and replace some hoses and rebuild the intake of vac leaks . when it stops raining ;(
