Wtf help.
I have a rebuilt cc503 lt pacesetter. 96 lt1. After getting it dynoed my tuner suggested to run ngk tr55. I had the Bosch quad prong style ones. The best they offer. He suggested that due to my power curves dropping. Well I switched them this morning and gaped them at .035
At first it ran decent but not better than before. Then after me starting it up again once I got home I had a nasty miss. If I power braked it the rpms went up and down. 800-1000 and driving it sounded like ****. I checked every plug wire 3 times now. I'm gonna check for arching in a bit but idk what happened. I guess I'm going to pull them out and make sure there not broken. Any suggestions on what to do before I remove them?

Yea of course! It'd be back firing up the *** if they were switched. Whatever it is it starts running really bad and then after 5 min of playing with it, it stops. But i can feel it like coming and going before it actually stops But I can still hear a slight miss.

But it's back and forth. As if a wire was breaking down or something. If it was constant then that'd be understandable. Unless the white material is broken then idk :/

I ran Bosch +4 plugs for 6-7 years on the orignal plug wires with no issues. I developed a miss and I changed to tr 55's and MSD 8.5s. A year later same miss so I went back to the Bosch + 4 a year ago, I've never had an issue with them.

ya dont run lat,s in a nitrous motr . the tr55,s are a resistor plug are u sure you didnt accidently close the gap on the plug on install thats a classic case of it .
