starting

[prazeo]

i replaced my battery for 98 camry not too long ago. but sometimes, when i try to start my car, it kind of lags. i had to rev it real high to start it one time.
the worst usually happens when i start my car and roll for less than a minute and then turn it off. then try to start it after a couple minutes. when i turn the engine off, i could feel it shaking (kind of like shuddering?).
any help? thanks in advance!
