I own a 1988 Camaro Iroc-Z with a 5.7 350 TPI motor.
I was driving the car onto I-95 at a speed of 65 when I heard a loud boom under my car, and pulled over to see what had happened. I couldn’t see what happened, so I drove the car slowly to a friends garage to find the exhaust pipe from the converter back to the muffler had split and blew apart.
I took my car to another shop to repair the pipe, but when I left the shop after the repair, I accellerated to about 40 mile per hour, I get another loud backfire and loss of power. The pipe is still intact, thank goodness, but I cannot figure out what is causing the backfire.
My friend from the first garage says it is a failing fuel pump. I never heard of such a thing to be honest.
I am at a loss and I have to correct the issue soon, as this is my only car to drive.
Please Help me ?
