Hello again, it's been awhile. My past problem with the misfiring was eventually solved w/ coil replacements, but another one has sprung up. After starting the engine (2000 SSEI 3.8L) and reach operating temp. it will momentarily stall dropping to approx. 700 RPM then resume to 950 RPM. when driving it will repeat when accelerating periodically also. Any Ideas?

Fist thought that comes to mind would be Throttle position sensor, but as usual, just a guess.

Stalling implies 0 RPM. Yours is dipping down? Might be the fans cycling on and off. Mine does a similar thing sometimes.

Have you ever changed out the fuel filter? How's your air filter? Just thinking basic first...does anyone know how a faulty PCV valve behaves? (curious for myself too)
