how high does it idle?

coolant temp sensor im pretty sure is one of the 2 which are located side by side out the top radiator hose just b4 the head.
make sense?
one is blue and the other is black
low water level is in the radiator fill bottle

the third one i havent seen b4. any chance u can post some pics?

now that i have seen pics i cant really help you as thats the old k-jetronic fuel injection, i was thinking that car should have had the digifant injection.
have had no experience with that setup
