Hi there, is No 1 fuel fouled? you may have a leaky faulty injector, also do a comp test, start here.

I don't think it is the compression. Car it have 67K miles on it.

Hi there,
If you have a miss fire in one cylinder only it will be either compression, spark fuel or vacuum leak, there is one thing i have learned in over 35 years in this business, that is you never presume anything is OK, do the basic checks first, this often saves a lot of time and money.
