Engine Performance problem
1994 Ford Thunderbird V8 Automatic 60,000 miles
my T-Bird drives fine at normal operating conditions,but when car is traveling at 71mph or above the car will start to shudder if throttle position is not exactly where it needs to be. Meaning when I hit cruise at 71-79mph and I go up or down a hill and the throttle has to adjust for speed, then it will start to shudder or pulsate. Any idea's? have already changed spark plugs.[img:03ec97f0c2]http://www.2carpros.com/forum/automotive_pictures/334032_042107_1842_1.jpg[/img:03ec97f0c2]
