Lost accerlation and brakes


#1

i just recently did w/a friend that is my timing and all that…anyway after that was done, the car seems to have lost some power and the gas mileage has gone down…



everything was changed…belt, plugs, filters, cap and rotor…etc…



i’m wondering if the timing is kinda off…?



2nd question, my brake light keeps turning on…and i just added some brake fluid and it went away…and now its on again?? the brake pedal seems to sink to the floor but it comes up…



oh its a 94 camry…4 cyc. thanks

should i bleed it?
