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.

So fuel filter has been replaced. The timing is advanced about as far as it will go and the car operates normally now. We advanced the timing so I could get on the highway without fearing for my life
 However I want the car to operate properly under factory timing. I have a feeling that it is spark or fuel related. Any help on this would be greatly appreciated. Thanks guys

I didn't have a timing light so I'm not sure specifically how much it was advanced. I have a friend that has a time light so I'll be going to his place this week to retard the time back to factory and then troubleshoot from there. Before the timing advance the vehicle did not misfire but had significant powerloss, most noticeable in the 2800RPM and up range. So far prior to timing advance: Spark Plugs have been changed Plug Wires have been changed(eliminated misfiring) Distributor checks out Fuel Filter has been changed -------------------- |
