everytime i part at a red light..my rpm often drops and come back up again..
also..wen i drive, sometimes it choked. its like there are no gas to burn or the transmission is kinda messed up ..so anyone knows what im talkin about..please help me out ..

 

my guess would be to check your vacuum lines, there could be a leak

 

how do i check the vacuum line?

 

just look under the hood, and check all the lines (usually black rubber) and look for leaks, feel around for air blowin around that is unusal, or a wrongly hooked up line or something,
