My Camry 2.2 L seems to be hesitating when you step on the gas after the car has been running for longer than 15-20 minutes. It happens after the car has stopped at a light idling and then you step on the gas. It also seems to be worse when you step on the gas after coming to a complete stop on a hill.

It doesn't happen all the time. I've had the injectors cleaned , gas filter , air filter spark plugs and wires replaced but it's still doing this .
Any suggestions will be greatly appreciated !

 

Year of car?

Does not happen when engine (coolant indication) is cold?

 

Sorry
It's a 1996 Camry 4 cylinder automatic and it never happens when it's totally cold .
I'll keep an eye on the temperature gauge tomorrow !
Thanks again for your help .
