8v is TBI , and all large illegal air leaks cause bad idle.
1200, A.C on, causes fast hot idle as does the P/S overload switch sticking closed. (ECU fast idle pins, set true active)
pure random. hot.
ISC sticking. (clean it)
i dont see how gaskets and seals can leak randomly, but is possible (rare)
when does the 1200 happen, hot engine, but when, fails to drop 800 hot. or pure random 1200, when was 800 say at every traffic light then next light its 1200? like that.
im sure the engine is really hot 180F. normal.
