My Mark running rough

[cmcallister6]

My 98 has been running rough lately it's not bad but I can tell its gotten a little rough. I replaced all fluids and spark plugs with oem factory motor craft parts and it's still running a tad rough. In park it's fine and neutral but as soon as I shift into drive I can feel it vibrate and feel like its running rough and when I accelerate it goes away. Only in drive stopped at a light i usually can feel it?

It must be your muffler berings.

What's your question?

Idle air control?

pour butane into your spark plug wells. thread the spark plug like half a turn in, start her up and the butane will create major heat and disintegrate any gunk in there causing it to run rough.
