My car is some times hard to start wont idle rite and occasionally stalls

Did you do a tune up? Change spark plugs Change spark plugs wires Clean throttle body with carb cleaner Clean iac valve with carb cleaner Clean maf sensor with maf sensor cleaner Let us know

also check fuel pressure

how about doing a good tune up also do a compression check to see if valve seats are leaking do a wet and dry check

need to check fuel pressure, I would suspect you will find it to be low. turn the key from off to on three times before you start the vehicle, on the fourth time, turn the key all the way, see if it starts right up.
