Do not guess at any one's word to whether the fuel distributor is bad or not. Have it thoroughly tested. Twice, if necessary. Fuel dist. are not hard to find. You can get it at Fastlane, but it's gonna cost around $550 for a rebuilt one, I think.
Installing a new fuel distributor is not an easy feat. Have an experienced mechanic attempt this. You will save lots of wasted time and headaches.
