Hey everyone I just bought a cb7 for $600 and the car is a 91 accord ex 2.2 AUTO with sports mode

Problem:
With I come to a stop light and step on the gas the car sputters and then I here a clump sound and the sports mode light light starts to flash ??? what could it be

 

Does it sputter any time you step on the gas and then clear up intermittently or only when you are starting from a stop? Does the light stop flashing when the car stops sputtering?

 

The blinking S light usually means a transmission problem. The generation Accord commonly had problems with the Transmission Control Module (TCM) or some of the solenoids.

There is also a chance your problem may involve the Main Relay; also in the link, which talks about it at the end of Transmission section.

 

Well the speedometer stop working to and for me to stop the car from sputttering I have let go of the pedal and then push the gas again and the (CHECK ENGINE CAME ON)
