I've noticed that my car makes the most power at 1/3 throttle. Any farther and it just bogs and makes even less power. Anyone know what that's all about? What's going on?! (IMG:style_emoticons/default/blink.gif) (IMG:style_emoticons/default/huh.gif)

I think that its both electrical and MPS. I think the dizzy's advance is not working rightand the MPS is having problems. A bad MPS goes rich but a car in good tune will still drive ok not the greatest but ok. Plugs will be black too.
Put a vacuum testor on the MPS to see if it holds 15hg for 5 minutes. If it doesn't hold a vacuum its toast. Install the dizzy when you get it and see the results. Geoff |
