Ugh new code. It finally got nice enough to get the Boss out today. Drove it this morning no issues. Went out this afternoon and got a CEL. I pulled the code and it was a P0352 IGNITION SIGNAL COIL B FAULT. It didn't stumble or run rough just threw the CEL and the DTC. I whipped it into the dealer to check it out since I'm planning to load it for BIR on Sunday and if I had a bad coil wanted to get it ordered and replaced in time. The tech tested the coil on cyl #2 and it checked out fine. They cleared the code and emailed Ford to see if they had any further instruction. I drove back to office and no code....yet but we'll see. Has anyone seen this one before? This is a new one for me but looks like it can be related to "misfires".
