Will not run right. Got codes 23,42,34,33,44. I just changed the minigolf gasket because it had a major vacuum leak and would not idle. It seemed to run okay for about thirty miles. I have been trying to fix this car for over a year. Also, occasionally when the check engine light is on and it is running really bad the speedometer does not work.

With that batch of codes I would look at the wiring around the intake. Easy to pinch or get a wire in the wrong spot and have it short out.
