1990 1.5 engine trouble
 

So I replaced the plugs and didn't fix it then I went to the distributor and found that the rotor was so loose it was almost falling off so I tightened it up and it ran ****ing awsome for like a min or two and now it still runs like ****, if I rev it it stumbles I start off in first not on a hill and it's fine but if I change gear and labor the engine it runs rough but once the car picks up speed it just all of the sudden runs fine. If I let off the gas it's fine or if I just give it the slightest gas when I labor it it's fine but a little more it runs like ****, but if I'm in like 2 doing 30 and not laboring the engine i could floor it, half throttle no prob. What the **** man

It could be the wires or distributor itself. My Mazda had a bad distributor that produced the same symptoms you describe. A bad motor mount could cause the engine to tilt but that scenario is unlikely. While the engine is idling, use a wood stick to move the wires around to see if the engine stumbles.
