I need some ideas
I've racked my brain, and I'm at a loss. I have this weird dip in my idle every so often. It was fluctuating really badly from 750 rpms down to 400 or so. So, I did the following: adjusted the timing, adjusted the idle screw on the TB (but I didn't ground the 1 pin black connector because I don't know where it is) i think it made some difference, then I replaced the cap and rotor, check the black tube for cracks and didn't find any, cleaned out the PCV system, ran fuel injector cleaner, replaced the plugs and wires, the O2 sensor was replaced when I put headers on last year. I notice the problem especially after I've been driving a while in stop and go traffic, when I have a bunch of stuff sucking power. When I come to a stop at a light and put the brakes on, put the clutch in, the car almost dies, but then the rpms shoot right back up.
I'm also getting a drop in power immediately after I shift gears when I'm gassing it hard. If I floor it, shift into second, there's hardly any power until 3500-4000 rpms. It still punches and you can feel the torque, but then it dies :(
So, any ideas? I think I've done everything possible :bwhoa1:
I hope it's not the alternator...that's expensive.
