I have a 92 c4 and recently my car has started cutting out at low rpms or when running thru the gears in between shifts and going back on the gas. I have new plugs, wires, new o2 sensors also have low coolant light coming on and off, coolant level is fine, someone took the radiator sensor out and can not find the wire, if someone has a photo of this it would help.

 

might just need to burp the air out and would look at the digital temp sensor or connection. and the idle control valve or clean. iac

 

Could be a head gasket leak. Under intense vacuum pressure when you close the throttle at high RPMs, coolant is being sucked through the gasket and when you hit the gas again it is misfiring on the coolant.
