Miss around 3000-3500 RPM

[jcostantino]

I noticed that I have a slight miss around 3000 to 3500 RPM and was wondering if anyone had any suggestions? My sig has all the parts I've replaced in the past couple years already listed so I won't repeat that.. I might not have mentioned the new fuel filter last year though.

There is a big oil leak through the back valve cover bolts which I will be working on tommrow but other than a hard starting problem (it can take a while to crank but I don't think it's the cam sensor) the car runs good. My superchip amplifies the problem so I haven't kept it in.

Once again, please remember this: for a misfire without a CHECK ENGINE light, it's the plugs and/or the wires.

They are about a year old and replacing them did nothing to my problem.
