So I changed my spark plugs bit now my car won't accelerate I have a ford escape 06 3.0. While I was changing my spark plugs I unplugged a few hoses from the intake manifold but I plugged them all back in right. I'm gonna put the old spark plugs back to see if they were defective. Is that a possibility? The car turns on but when I step on the gas it won't accelerate at all. But it moves at 2 - 5mph of course. What are other possibilities for this kind of problem.
