i have an 88 maxima when the engine is cold it hesitated on acceleration,but when it warms up its fine

Q: what could be the problem? pls help someone thanks is it a sensor,? i changed the coolant sensor,,,

A: Check your water temp sensor. it is suppose to tell your computer to run rich when cold. Cold engines does NOT run well unless it is in choke mode (run rich mode). == > i changed the coolant sensor,,, OK, but it could still be the bad new sensor, connectors, wires to the sensor. good Luck...
