When i drive my car first thing in the morning the car is hesitant and bogish almost feels like its starves for gas. When i give it more gas its slugish and jumps out of it and is smooth. This only happens in the morning, during the day its doesn't do, only sometimes.
I just recently changed my iacv and tps. Installed new fuel filter aswell. I thought i was getting bad fuel pressure but hooked up a gauge and getting 38psi.
So i have no clue as to what it could be
Any suggestions would help.

 

i would tripple check the tps voltage that is very well known to give you those symptoms after changing it

 

thanks i'll do that

 

i dunno if they are the same problem, but my car does that also, in the morning after its been sitting all night, if i give it gas in say the first...30 sec to 1 min, it boggs and seems to wanna die.

ive realised now that this is actually normal warmup behavior, atleast for my car. it never happens after like 30secs of stastup. my buddy tech at honda tells me its just getting info from sensors and such, and takes a few seconnds to be ready.

but as i said before i am not 100% sure.,

 

thanks for the info, and ya my car is fine during the rest of the day. But every now and again it will do it during the day, but very miner. I will have to look into it further.

 

My CR-X did the same thing, 38psi is not enough fuel pressure at idle, bump it up to 45 or 50 psi, your car will run better also!

 

I have a stock regulator, could it be on its way out. If i disconnect the vacuum hose from the top the pressure jumps to 40psi at idle.
Is that normal

could possibly be a poo poo injector. im having similar problems w/ my d16a6. Ive got some spare injectors im going to swap in when i get a chance.
