Still a miss at higher rpm's

[Troutman53]

2000 Grand Prix GT. I have replaced the MAF sensor,MAP sensor, TPS sensor, and fresh plugs and wires. Air filter and fuel. I used NGK platinum plugs. Could these be the problem. Wires are Belden so I trust those. Do N/A's hate platinum also?

could be the plugs. id toss some iridium plugs in there.

Any GM 3800 with a waste spark system hates platinum plugs.

Kinda what I was suspecting. I'll grab a set of AC 41-101's today at work. Thanks for the help.
