Stan, Also, on each bank of the engine in front just behind the fan belt area bolted to each top side of the engine, there is an injector? something?, one for each side where one was obviously replaced when I bought my car. One had cosmoline on it and one was bright and shiny. If I had my receipts I could look up the name, but I remember being told it could cause only one half of the engine to work. This board is great but unless someone with first hand engine knowledge like Mark Fling shows up and lays out the different options and how to check them, it's sort of hit and miss on here. Better than nothing but when I get the time I am sure going to spend awhile getting to know the particulars of these engines. Kurt
