So I've got this issue with my car. It drives relatively normal up to ~ 3500RPM or so and then there is a major drop off in power. Accelerating feels compromised. I though I may be having issues with o2 readings so I checked the sensors today. I unplugged the sensor on the back of the motor and have no check engine light. I know that the sensor used to throw a code when it was unplugged previously. I am still unsure what's causing the power loss. Does this sound spark related to anyone? Thanks for the help.

hhmm yes, your plugs could be fouled. does the car stumble a bit after 3500? if so it could be a clogged fuel filter, or an injector issue.
then agian how much of a power drop are we talking about. the 7a isnt the most snappy. -------------------- It takes 8,460 bolts to assemble an automobile, and one nut to scatter it all over the road.
