My 94 Accord idles up and down up and down then Smooths out when warm then when
What is your question?
It seems to have a throttle position sensor problem it does similar to a carbureted engine it goes up and down up and down with the idle then the the light comes on check engine and then when you press the gas or a warms up it Smooths out and will run just great you let off the gas to idle goes up and down up and down I'm thinking it's the throttle control valve but this is my first time to I'm a senior 60 years old I guess that's a senior retired from working on vehicles and mainly body work and framework painting give me an idea and I'm sure I find the problem making resolve it
What makes this problem better or worse?
Yes it seems to be worse when the engine is cold
