I have a 96 Accord (2.2l) around 162k miles and recently I began to have issues when starting the vehicle when the engine is cold (most noticeable if being started for the first time that day). The engine cranks but once it starts to run it sputters and dies quickly. When I go to start it again, it runs and still sputters a bit and after roughly 15 seconds it gradually sputters less and the idle smooths out. I do not have a Check Engine Light. After this the car runs perfectly fine, any ideas?
