Has trouble starting. Dies when coming to a stop

it appears you have electronic throttle control. any applicable trouble codes, relating to that system? clean the throttle bore and around throttle plate, don't force the throttle plate. your idle air is electronically controlled.

Deffenitly get a diagnostic done first. Usually those symptoms indicate a bad ignition coil or a malfunctioning IAC idle air control valve but honestly, that could be a million things. Trouble codes can point right to the problem. Never just throw parts at a problem.

code p 0720 refers to output shaft speed sensor (OSS)---circuit malfunction===causes ---wiring --- OSS sensor--- ECM---TCM
as the OSS reports shaft speeds to the TCM so that he correct ratio can be selected, I would be having it tested / replaced

MR Donley just clean the throttle body from dust dirt.

sounds alot like a vacuum leak.

Take the car to camry automobile shop for the servicing of the car.

idle control valve is going bad also the MAF sensor may be clogged alumminum piece between air cleaner box and throttle body

Try pulling I A C (idle air control) motor & cleaning it good with throttle body cleaner , as well as port it came out of . These quite often get gummed up at pintle of motor (pointed part) and shaft, which cause it to stall etc on corners, under load etc. It maintains proper idle under these conditions. If it cures it only for a while & starts to do the same again, change the IAC motor. They never, or very rarely store a code, so it isn't something that comes to mind very often unless experienced with symptoms.

Have the idle air control valve checked.

Chugging down? Do you mean your engine is almost stalling? Sounds like your fuel filter is clogging up. Change it before your fuel pump dies. A Fuel Filter's like $10 - $15.
