Hi everyone,

I sold my '87 that I did a rolling restoration on and took the profit to purchase a '94. I can not believe the advancement in the car, it is almost a new generation.

I purchased the car from a dealer (which is a good thing). After driving it for about a week I noticed something very wrong: If I hold the rpm's at 2000 after about 3-5 seconds there is an awful misfire/stumbling, the tach goes from 1000-3000+ the oil pressure is bouncing and the car shakes pretty bad. If i step on the gas and force the rpm's up over 3000 it all stops (below 2000 it smooth) Also, at high speed/rpm's it happens again. like around 4500.

I returned it to the dealer to have it fixed. he has had it for a week and told me they have no idea what the problem is and cant fix it.

First does anyone know what this is? I was thinking opti-spark, but dont really know...

Second, if an option is to send it to a vette specialist should I? Or should I just give it back? Option 2 is harder than it sounds; they get 3 chances to fix it and this is only attempt #1

Thanks

What have they done to "try" and fix the problem?

new plugs and wires, fuel pump checked, basic tune up.

Maybe the car was detailed before purchase and the Opti got wet inside.. during a cleaning.

I did ask if they power washed the motor, and they said yes. I mentioned to them what can happen to the optispark when that happens...
