unplug it and take it for a run as the ecu runs it at a default value if its unplugged, so if it runs better then 99 times it gonna be the sensor.

can also do the same test for lambda, if it runs better with it unplugged you need a new one

Try coil pack again, had the same problem last year swap it for a known good one. There a big problem on vr6's.

Been through 4 in 3 months.
