Lately, I have had random stumbling on acceleration. No CEL and I replaced the fuel filter. When I checked the distributor, I found that the rotor was loose. The cap looked okay and so did the rotor. I'm hoping this was the problem. What do you think?

 

Possibly did you tighten up the screw or replace the rotor?

 

Tightened it for now. I'll get a new one Monday.

 

Why get a new one if it was just loose?
Would you buy new wheels if a lug was loose?

The screws are notorious for backing out.
Put some loctite blue on it and see if it backs out again.

 

Took her out for a spin to the store and still have the problem....any other suggestions?
