Hello,

99 V70 is developing two new issues.
1st, when i come up to a red light, the idle drops very low, then stabilizes.
2nd, at highway speed, when i try and accelerate to pass, i get an intermittent misfire or stumble. around town no miss.

Things I have done related to this problem.

new Idle control valve

new fuel filter

new plugs, the center electrodes were quit worn. middle Cyl. had some white fluffy stuff on it and the porcelain at the base was a bit brown.

Clean MAS

Flushed tranny with 3 Gals. ( at first I thought the stumble was tranny slip)

I would like to further test the MAS but dont know how.
