hey guys new member here. My srt6 has a terrible rough idle that used to be infrequent but has gotten worse. It started about a year ago, I would drive down the highway and it would go into a low power mode, and start to roughly idle. Usually takes about 30 minutes to restart. It’s gotten worse lately.

So so far I’ve changed the park plugs, the coil packs, had a shop check for a vacuum leak, I’ve changed the crankshaft position sensor.

Its still rough idle/low power mode upon start. I’m feeling beyond frustrated.
