FYI there was no '99 or '00 WR 426, they were '01 & '02 only. Now back to your problem. Try a new plug, I had a similar issue with my 426 and started there before getting into coils, stators etc. Oh and try using a little punctuation, I think you will get more answers from TT'rs when they can understand the question. Good luck!
