LT1 sluggish and loss of power
Ok guys picked up my first Lt1, always had an ls but got a deal I couldn't pass up, and forgive me if this has been addressed in the past but couldn't find much on it.
So whats happening is under acceleration it occasionally becomes very sluggish and loses power, as if half the cylinders just stopped firing, then comes back to normal. I replaced the PCV valve on it and it seemed to fix it for a day or two but then started doing it again. The old one had what in my opinion was quite a bit of oil in it, so I figured it was sticking. Not sure if an opti rebuild or coil replacement would be in order as well? Under normal driving its strong and full of torque, but when it bogs down its awful and just doesn't feel good.
Any info would be appreciated, thanks.

Could be the opti; I would do a full tuneup and replace the plugs and wires first though, fuel filter too. If that doesn't help any, I would look into troubleshooting the opti and coil.

Opti spark solved my issue that was similar to that. Before the car went through a little "restoration" it felt sluggish, started hard, and just ran like crap. Bought a chandler motorsports opti off of ebay and all is well.
