I took my 90 vert out for a spin after rain stopped here in FL, was running good for about 20 miles and severe bucking out of nowhere occurred. Engine light came on and tach went crazy. It would die then start right back up. I crippled it a few miles and after about 5 miles it went away. I ran the codes and nothing came up 00. Any thoughts??

I did a brief search and most people had codes associated with them. I had none?

 

Overnight bump. Best I can tell from a search is OMP or TPS, but each have a Code associated with them. I had no codes.
