Bad optispark?. Leaking water pump
1994 z28 a4 I've had the car sputter under load and does it when warmed up. I've changed spark plugs, I had a hole in my intake elbow so I have a new cold air intake. The water pump has the fluid dryed up on the seams and may have leaked on my opti. To cause the car to run like s#*!, never had an lt1 only own an ls1 so need help ASAP. It's hesatiates around 1000-2000rpm. Just don't know where to go from this one.

may want to give the opti connections a look ror corrosion. Might be worth spacing the icm and coil off head(shoebox has instructions for that). May also be time to check codes and datalog. Checking fuel pressure cant hurt either(but not my guess). Thats all I could offer up. Good luck.

Re: Bad optispark?. Leaking water pump
If your water pump is leaking change it and the opti at the same time.
That's what I'm currently doing and am now waiting for an opti to ship in, wish someone would've told meto buy a new opti with the pump.
