Passenger side front plug. 135 on the right 246 on the left. Number one is always the closest cylinder to the front of the engine!
i was afraid of that, the hardest one to get to. thank you very much for your answer.
U welcom and it is a pain! Engine misfire? And do the coils still feed two cylinders each?
If so and # 1 has a misfire it could be the coil which is on the front bank i think. If you are lucky.
i changed the timing belt. the instrutions said make sure no. 1 is top dead center. thats why i wanted to know where one was. i got it all back together and it purrs like a kitten. thanks for your help.
