every morning when i start my h23 it idles real (real) low if i don't let it warm up then it will die when i get to the first stop light at the end of my street. then the next street then i get on my local highway and it is fine when i get off at my next exit and so forth. i can actually feel whatever the problem is clear up when the car completely heats up. but when it is not heated up you can feel it actually bog when shifting but once it is warm it acts fine. it will die at the same places everytime like clock work. if i keep my foot on the gas like it is supposed to idle at i also noticed that when it is acting up the rpms drop a lot more sudden then when it is warmed up. new plugs, coil, knock sensor, timing belt, and new distributor from honda recently put on. also sorry no cel. i have been dealing with this for about 2 months hoping whatever it is will break or throw a code but no luck yet.

 

Could be a number of things, but I would pull the IACV and clean it out to start with.

 

do i need to drain the coolant to do that or does the end that attatches to the manifold just see air?

 

Nope, just leave the coolant lines attached and remove it from the intake manifold. Sparay it out with some brake cleaner and re install it, replace the O-ring if they are worn.

 

replace the coolant temp sensor.....does the idle jump to normal when warm?

 

yeah idles fine and runs fine it just seems like it needs to warm up. i have tried starting it a good 5 minutes before i drive it just so i warms up to where it wont die on my the first stop sign i get to

 

anyone else?
