'93 3.0 rough when cold, help please.
I have a '93 3.0 5 speed with 169,000 miles. When it is first started and cold it will get a bad flat spot and stumble when I step on the gas. When it warms up, 5 minutes of driving aprox, it runs fine, smooth and good idle. Got any suggestions on where to look? the plugs are new NGK's and the plug wires are good, intake clean. thanks for the help.
