Tec-II Engine Diagnostics
I'm having trouble with my car. It's stuttering when cruising and the idle will hold solid and then dip ~10 RPM and come right back and WOT power is not where it once was. It's like a coil or injector is intermittently failing. I've replaced the plugs and wires which did not help. I'd like to get it diagnosed but I'm leery of taking it to the dealer with the car being nowhere near stock. Would they be able to hook it up and tell me if I have a bad coil pack or injector?

I have been logging all sorts of stuff with my HPT but it's not showing me anything glaring. cylinder balance test is not supported for the gen 4's. I would think thats something they could do with the Tec-II.
