Please Help!!!

Some days my Z28 won’t start and when It does start the car revs extremely low and when I push the gas pedal to the floor the car tries to increase in rpm but dies at 3000rpm. The LT1 does have a delteq coil conversions and I want to know if that’s the problem and if I should switch back to an optispark. Please help!!

What year is the car?

Is it throwing any codes?

Does the car still have cats?

Does it ever run normally?

The car is a 1996, It does have cats , and It sometimes runs. The check engine light has not came on I think that’s due to the delteq coilpack.

I would suspect the Delteg system can fail just like any other ignition system be it parts or error in the install of it.

If the Delteg maintains the ICM...would be something to check/replace

Ignition Loss

Hi, the sound of your engine problem is an ignition loss sound.

I would test the ignition power feed.
I would test the position sensor output.

I do sell a new "opti" for $128.00 FOB.
