I have a 95 max and i just changed the spark plugs on it. I've always had kind of a rough idle with it, but now that i changed the plugs it has gotten worse. I noticed the old plugs that were in it had oil on them and one of them didn't have a gasket on it. The problem is that when I put the car into gear the idle jumps up and down between 400 and 500 and feels like its going to stall, but it never stalls. I thought the new plugs would help the rough idle, but it seemed to have made it worse. Any suggestions on where I go from here??!!!
