My 1992 civic 1.5l has fuel injection and all of a sudden it acts like whatever replaces the choke in a fuel injection engine doesn’t work any more. Harder starting when cold and hesitating when cold. Where do I look???
The coolant temperature sensor for the engine management system (some cars have two, the other being for the temperature gauge).
Your vehicle has three coolant temp sensors. One for the engine management, one for the temp gauge/light on the dash, and one for the electric radiator cooling fan.
Low fuel pressure can also cause this type of problem.
Hard starting and hesitation? Had a tune up lately?
