1990 subaru legacy 2.5l auto awd 350000km. When going uphill or hard acceleration the engine will start to ping then vibrate serverly and then dies. I will pull over and turn off then it will restart and run smooth. The engine start to ping then seems it loses1 or 2 cylinders thus causing lose of power, vibrating and than stall. Other than this the engine runs smooth on idle and drives smooth until I get to a situation where I need more power for more than 5sec.
Burns on oil, Compression is 180-185.
Parts I changed. Plugs NGK, plug wires, coil, O2 sensor, MAF sensor, fuel pump, fuel filter, air filter, timing belt, knock sensor, exhaust system cat and muffler. Have run sea foam and TKO injector cleaners.
I am not showing any codes. And gas millage seems to be OK
I am running out of thing to change.
I bought the car knowing of the problem but I did not count on it been this much of a problem
Any help is appreciated
