Hey, I just picked up this car and pulled the timing back from more than 30 (couldn't even be read!) down to 10 for now. I also did plugs/wires/oil/coolant etc etc beforehand. After pulling the timing back from a rediculous level to what it should be, while the car is cold it runs alright, but when it warms up (im assuming warm based on driving time, temp gauge doesn't work), the car vibrates a whole bunch, has a huge power loss, and sounds alot choppier. In addition, I hear a slight ticking coming out of the exhaust. Ideas/suggestions? Thanks.
