Question: performance issue

[Lippy]

I am trying to understand why my 86 corvette is popping thru the exhaust when I accelerate but still performs well?

If it's "popping" out the exhaust on acceleration, you may think it's running right but it's not performing well.

Without understanding a little more about the problem's characterisics, "popping" or "backfiring" under load when accelerating is often a sign the ignition system needs attention. In what condition are your spark plugs, plug wires and ignition coil?

Popping thru the exhaust /performance issue

Let start by saying thank you very much for helping me with my car. I don't know anything about Corvettes But, I will be learning with everyone's help, and when it is possible I will gladly pass my experience's on to others in this forum.
I just realized it is time for the smog cert. So I am going to look into changing the spark plugs & wires.

I don't get to drive my car much, I may have put 10,000 miles on it in the last 3 years. I know I put plugs in it at 2 years ago. I had an issue with it shutting off at one time and the coil was changed out and that problem was resolved. I haven't changed the wires yet but I am going to change them as well.
Thank you again

Performance issue

Well just to follow up on this thread, I found out the popping was not coming thru the exhaust, it was happening when I accelerate but was coming from the rear end when the clutch pack was trying to lock up. I serviced the rear end and the popping stopped.
