Hey looking for some help with my 1980 cutlass calais . currently has a stock 305 with a th350. It recently developed a problem when shifting into gear the rpm's would drop severely almost like it was missing a cylinder but if you touch the throttle it was fine . i thought possible vacumn leak . i plugged the line going to the air cleaner temp sensor and when shifting into gear the car didnt run like a p.o.s. and seemed to hold idle . while inspecting this problem i noticed that what i believe is the transmission kickdown cable linkage to the carburateur was very lose . the link on the cable has a long area to slide on the part attatched to the carburateur. It seems like there should be some kind of retaining clip . so im wondering if its supposed to be like that or if there should be some sort of clip .i havent had the car for long and has been somewhat of a headache ever since i bought it as a replacement to my 80 supreme that was vandalised . any help with this is greatly appreciated.
