I have a 1990 GM Chevrolet Cavalier 2.2L AC PS PB that shows this problem: when going uphill engine gives a tick-tick-tick sound and no power. When I step on gas pedal on highway or on street, engine gives a tick-tick-tick sound and no acceleration until a long time 2 minutes later. (This problem came on about the same time last year when the AC stop working, blew a fuse. I replaced a fuse, AC still not working. Compressor will not kick on. I short circuited the relay and I can get the compressor and fan go on.) The car has filled with premium gas, still tick-tick-tick. Car has metal timing chain and no timing mark. It has electronic crank position sensor for controlling timing. Compression on all 4 cylinders are perfect. Vacuum test at 20mmHg steady no fluctuating. No sign of oil in coolant, and no sign of coolant in oil. Any suggestion?
