I got and put it on. Took all of 2 minutes to take off the old one and put the new one one, disconnect the battery and re-connect the battery and start the car. For the first time since I have had the car in 7 years has it started right up on a cold engine. and idled and drove it. It did have a little hesitation. Does it need to be adjusted? It also might be that my spark plugs are all fouled from driving it with a bad Mass Air, the car ran so rich.WOW you could smell it. Any suggestions on what I should do to dial it in?
