Re: Compression results help 94 4.0
If when you pull the plug wire off #5 and the idle doesn't change at all, you have a dead cylinder. Could be a bad coil pack, bad wire, bad spark plug, bad injector.
That low compression has me a little puzzled. 130 is a bit low but it should at least fire and you would notice a change when you pull the wire off. You may have more than 1 problem. Either way, low compression is almost likely a mechanical issue. Bad valve, piston ring, head gasket, etc, and would be the main issue.
