I have a 1990 that idles rough. I've changes plugs, wires, rotor and cap. I have a vacuum gauge installed in my car and it runs about 17 at idle. I have installed a K&N Filter and I had trouble making it fit perfect. Also, the flame trap lines are not snug. Can these cause a vacuum leak? If not, what is next?
My engine light is not on but it is idling rough. Oh yes, I have the VX cam, can that make a rough idle? Please help. My mechanic wants to adjust the valves, will this help? Thanks for the input.
