Explosions thru the exhaust pipe,Help!

[BLAZERING]

92 Blazer s-10 4.3 l
After changing distributor cap and rotor and driver side knock sensor(engine started to miss and die while turning or stoping) ,i started to get very loud explosions thru the exhaust pipe,even thought it idles much better,also i noticed a reduccion in power while driving.Any of the Gurus here has any opinion?
Thanks
PD the explosions happens while i get my foot off the pedal ,as soon as i accelerate they will go away.

did it start as soon as you changed cap and rotor? if so check over your work make sure correct firing order, and that both cap and rotor are setted properly.

I rechecked the firing order on the manual ,the cap and rotor are seated properly and yes it started just after replacing the cap and rotor.
Will the engine even start with the spark plug cables connected wrong?
The idle seems fine...

if it started with the wrong fireing order, your replacing the lifters... you would know that by now... only thing that comes to mind right now is a sticky exhaust valve, or something along those lines

The firing order is out for sure.

Do you have the TBI or CPI 4.3L?

It is the CPI 4.3 L, isn`t the firing order 2,4,6 passanger side,1,3,5 driver side ,clockwise?

[BlazerLT]

Do you have the round distributor or the horizontal one where the plug wires plug in from the side?
