my car had a intake valves cleaned and the whole engine was down. in the process coil, plugs and some injectors were replaced.

i can hear flapping sound coming from my dash. and it sounds like the cams timing? this happens after 4k rpm.
now, it keeps getting misfiring error at 5-8 cylinders
02 oxygen bank 2 error which might be due to catless catalyst converter.
car cranks weakly which i have also replaced the battery

all of this was due to 1 bad injector that squirts fuel even when ignition is off. causes engine overfill with the fuel. EPC + Cell came on then.

im in a dilemma to have the engine remove again. because its alot of labour + hours.

anyone had the same problem before?
