excellent work, went right to the problem where 2 other mechanic shops failed to find it. Water was leaking into plug cavity and causing a serious misfire and a certainty of failure when smog check was done. The cost of the repair was mostly parts charge from Nissan. Vehicle repaired is a 1999 Quest with 198,000+ miles on it.
