ok this is gotta be the wierdest thing ever to happen to me.the car sat for a week 1996 civic ex w/ lsvtec ran perfect before it went in the garage.tried starting it and would just crank and crank. i put new coil and spark plugs and wires.tried to start the car it would start barely.so i unplugged the o2 sensor and it starts up now but sounds like a subaru wrx.sounds like its running on 2 cylenders when i give it gas.but at the same time its blowing a tremendous cloud of white smoke out the muffler.the motor only has 200 miles since it was built.Any clues or someone have the same problem lmk here or Im me thanks!

sounds like headgasket, coolant leaking into the chambers could make it run rough and rumble.

white smoke could be coolant burning.

 

major coolant leak

 

maybe when it sat, the coolant filled something somewhere?

Only reason I can think of it would do it after a week of just sitting, ya know?

 

ok that would prob explain the white smoke by why does it sound like a subby wrx lol something is majorly wrong i think
