Hey List, Now that I got the timing right (using timing light, the notch on the crankshaft lines up with the 13 degrees notch on the plate for cylinder #1) but now I am getting a high idle, and my frequency valve doesn't buzz at all. I was wondering what direction I should start looking in? Also I still have the original lambda probe installed, the wire is cut from it, and I still have to remove it to put the new one in. Since the lambda probe is only used when the engine is hot, I don't think this is causing a problem right now. My car is idling at around 2000 RPMs. Plus, when I rev it hard I get backfiring into the intake. Thanks for any help anyone can give me!
