My 86 alfa romeo has been acting up. Occasionally it will misfire (it could do it more often than i realize). I will be having a new clutch put in as it does occasionally slip. However twice it has hesitated like a carbd car when the carb is not properly tuned. it was fine when I shifted into N out of any gear. I revd it and she was fine. It was like she couldnt put the power down and she didnt like having the pedal floored (wasn't driving like a maniac, just running tests on it). It would go then no power (not slipping at that time or reving any higher) then go with power again. I recently awoke the car from a long slumber and I drained all but 2-3 gallons of the old gas as that is all I could get out. Mixed in new gas with some additives. New cap, rotor and plugs very recently. However i did not do new wires as I was sent the wrong wires. she was running just shy of the 175 mark on my temp gauge which is right in the middle. It had no signs of overheating. Oil pressure is fine, right at 57, though sometimes when idling the gauge will drop. The coolant does need a flush however no overheating signs present. I let it sit for about 10-20 minutes (luckily it happened in front of a friends house) and was fine and continued down my merry way. It did not cool down much in that time as it was sitting in the very hot Hawaiian sun. If my memory serves me right it was around 130-140.
