The problem:
At certain points during the acceleration curve, when its at the highest stress level, my 01 civic starts to have some serious misfiring issues. Usually between 3 - 4k rpms the engine in my civic starts to have random (per the engine codes) misfiring on all of its cylinders.

Its not the plugs or the fuel pump. Can anyone think of where I should go next? I am absolutely stumped on this one.

Any help is greatly appreciated.
Thanks

 

timing?

Very well could be.

It could also be some injector misfire problems, or the dreaded, and somewhat common Crank position sensor issue.

I'll find the FAQ on it...

 

could it be the coils?

 

I would be very interested in anything you could find. Than you so much.

 

So is this a stock motor or what?
Need a little info on the motor and whats running it.

 

Any other info from the codes? If its on all 4 cylinders it sounds like an ecu/timing issue.

 

yeah its a stock vtech 4
