01 S throwing 301 code. Runs rough and engine light flashes, then burns steady, then flashes both at idle and while driving. I found and fixed 2 vacuum leaks and changed #1 coil and it ran great for a day then started chugging again. New plugs, injectors are clean. Am I looking for more vacuum leaks or something else? Thx

 

what plugs did you use? and be specific with the part number. was the coil new? since the code is cyl specific, most common is the coil or the plug. are there any other codes?
