I have a 1976 cj5 renegade with a rebuilt 304v8. i replaced just about everything else under the hood when i bought it. it was running fine untill recently it started to lose power when i accelerate. it feels like i trying to pull something thats weighs way more than my jeep can pull. it also sounds like air is escaping... the tranny is also having some issues. when i shift into secon gear it pops back out... i am sorry if these questions have already been asked, i searched and couldnt find any answers...
