The code-reader @ AutoZone said "Cylinder 1 misfire". I bought 1 spark-plug, then pulled, cleaned ALL the sparkplugs (& put the new plug in cylinder 1). Also sucked some Seafoam into the vaccum. No difference. Well I JUST left the auto shop with $160 less in my pocket. He replaced all 6 spark plugs. I could have bought 6 at the store & saved $130, but I'm too-much of a dumb-ass.

My 1998 Ford Taurus has high miles and has started to intermittently blink and throw a cylinder #1 misfire.
@splaytrees
A transmission shop mechanic looked at it yesterday and thought it was the engine valve [cyl#1]. He listenned to the injectors click, disconnected plug wire #1 and looked at the spark from cable to plug - both good. (Plugs were changed 10k ago). He said he'd have to pull the head on bank1 if we were going to fix it. KTNWO has a great suggestion - I'll try the tailpipe test probably tonight.
@splaytrees
Just tried it. After seafoam treatment (yesterday) into the a/c vaccum line (back-driverside), bank1 fuel trim (short+long) at idle went from 5% to 10-15%. It currently howers around 12%. I now have 1/2 a bottle of miracle oil and 1/4 can of seafoam in the oil LOL.
@splaytrees
Thanks, you might be right - I'll post an update once it's fixed. I'm baffled why I get a strong spark/arc when I disconnect plug wire#1 from the distributer and hold the cable an inch away. I've posted on c/l and someone suggested bad lifter or bad valve.

To all with this same problem. Check the cable that comes from alternator to fuse box near to battery look for cracks or damaged wire i have the same proble and got surprised how do i solved
@edwardhhsu
I have a 97 with exact same problem. Not wire. Not sparkplug. I am going to check vacuum.
@edwardhhsu
My gas milage is not going bad. I think one fuel injector is not injecting.
@MicroRest
mine is doing the same thing.
@mesatreecare
