Back to ignition hell

[typhoon-crazy]

STILL trying to get my ignition stuff all correct. heres what i got so far, ngk ur5's, atr black beauty plug wires, brand new msd distrubutor, new msd coil. at idle the truck has a weird poping noise that almost sounds like a miss. the "poping" noise isnt consistant. then sometimes above about 3k the tach jumps around but the engine rpms are following the tach flutter. i have asked this question before but now i am really stumped. what should be my next step?

this may be too obvious...but maybe you have a few plug wires crossed or phased incorrectly on the cap.

Replace the MSD stuff with OEM GM parts. Quite a few people have had issues with MSD stuff that goes away when they put the stock parts back on...

alright ill give replacing the msd coil with a stocker. and ill see how it goes. is there a way with a volt ohm meter to check my plug wires to check if the are ok?
