For 1. Don't use cheap Chinese made parts like coils. 2 of them where sparking in plug well. Replaced with. Sp 515 plugs and OEM coils . 2 . The cat on drverside is bad . Not plugged. Replacement will be. Direct fit. Walker unit. Looks exact same as OEM 290.00... gonna do swap myself

Runs smoother now but not perfect . Still get a light

 

Yep...you get what ya pay for....

 

Lessons learned.!! I'm sure the cat was going bad. Since I bought it
