Randon Misfiring and Backfiring
i have a 98 blazer and i recently had an issue of a random cylinder misfire so i did a complete tune up on it and now it runs the same and backfires on me...so i am so confused on what to do next, so if you have any thoughts or suggestions please let me know

did you use ac delco plugs, wires, cap, rotor etc? did you remove the distributor and are you sure you got it back in the right place, it can be off 20 deg and still run, but run like crap.... also have a read thru this if you have not already done so https://blazerforum.com/forum/showth...0300+explained

When i replaced my rotor I did not get is seated all the way. It would do random misses and chugging. took me a bit to figure out what it was. Didn't look at what I had already fixed. Silly me. reseated the rotor and tightened it down and it was all good.

i used acdelco everything and everything in on just how it came off and tight and all the plugs are in nice and tight and the wires are all on tight too.... but after the tune up was done it still ran like crap and now backfires
