I replaced the plugs cap and rotor. the rotor center metal thing was pushed down compared to the old one . same acdelco.??? wasa it bend down by accident or its ok? cleaned the throttle body alittle and cleaned the mass air flow sensor with mass air flow sensor cleaner. it fired right up by my rpm gauge which it was kinda doing before is very sluggish on the response and not my MPG gauge is pinned at 100mph. I replaced a vacuum lines that were dry rotting. what happened?????????????

 

I had the battery disconnected when I did all this . I did have to hook it up to roll up the windows last night when everything was apart but nothing was touching anything . it also seems like its running at a higher idle alittle bit not sure if that is from the rotor being bent or any of the cleaning that needs to readjust after alittle driving . I also did not replace the spark plug near the steering drive shaft to much of a pain . lol the plugs weren't horrible so that one should be fine

 

ok replying to myself the mph guage auto corrected itself after driving a minute or two and back to normal. lucky lucky so car
