Question about 1991 Honda Accord
Was on the parkway when slowly started losing power, engine idled rough, then finally stalled altogether. Changed spark plugs (NGK G Power), wires, cap, rotor, still rough idle and have to rev high to keep from stalling in gear. Pulled plugs and cylinders 1 and 2 have oil on them and 3 and 4 don't. A friend of mine said I m may have a bad head gasket leaking oil in the cylinders? I have no coolant in the oil or vice versa. I had the car for a year almost and I knew it always burned oil, but it always ran well with full power. Just a little smoky when I gunned it I only used high test gas so I don't think it's a fuel problem.Help!
Check cylinder pressure,if OK, check MAS and fuel injectors

Could be head gasket or piston rings. Piston ring issues will smoke under load or when revving the engine.
Do a compression test.

Engine stalling and rough run
issue at low speeds
is commonly caused by a dirty automatic idle speed control valve and
throttle valve. Buy a can of throttle valve cleaner (do not use
carburetor spray cleaner!) from NAPA or Carquest (made by CRC
chemicals) and spray it into the air intake while the engine is
running, use up about 1/2 the can, engine will try to stall hold the
speed up, shut it down and let it soak for 30 minutes, restart and
blow out the remaining fluid, shut it down and disconnect the
negative battery cable for 5 Min's to reset the base idle control. If this doesn't improve the problem you have mechanical problems in the engine like a low cylinder die to worn rings or leaking valve seats.
