'86 Celebrity 2.5L 4 Cyl. 86k Miles. I got this car free from a friend and it was pretty rough to begin with. after it stalled out and would start for a long while, i took it to a mechanic who replaced the ECM and all the sensors. few months later the exhaust had a huge leak and got that fixed but he said the catylic convertor was rusted out and needed to be replaced but it's still on and also got a new fuel line. after the new line i noticed fuel milage go way way down and i dont do any crazy driving, i estimate 6-10 mpg. i replaced air filter, and as i said before the sensors are only a few months old so i cant figure the fuel milage problem out. also i overheat alot, after about 20 minutes of driving, i noticed that antifreeze would spurt out of the reserve for some reason but not realy sure and after i turn off the car, i can sometimes here a buzzing that sounds like it's coming from the trunk. i barely drive anywhere (800 miles in last year) and i still spend $20 on gas every week or 2

For the over heating, Problem does youre cars cooling fan kick on when its get hot?. Also has youre cooling system been serviced lately?. Could have stuck close thermostat.
