Ok after the car gets over 3 rpms it picks up a little but then after the car warms up it starts to bog alot more.

Here are the things i have done
1.Checked timing
2.replaced rotor
3.replaced plugs
4.replaced plug wires

Could it be the fuel pump? what else could it be please help me out

 

yo try the fuel pressure regulator i tried it the other day on my car and that was it after changing everything else on the motor so try it its possible its letting to much fuel by thank u rioninja

 

civicboyzc........check this out...i'm not sure if it is...but it was well describe. the fuel pressure regulator could be one thing too...but this is fully describe. i havent fix my problem yet similar to yours but i'll try the fpr first...since its easy to replace.

but check this out..... that was posted a few months or weeks back.... https://honda-tech.com/zerothread?id=56731

 

how bout checking you have your spark plug wires in the right order?

 

1-3-4-2 firing order......civicboyzc and i have checked that already.

 

I used a fuel pressure regulator off of my si fuel rail today i still get the same bogging/hesitation and it still gets worse as the engine warms up

 

vaccume lines are they correct the plugs check em to see if they are fouled check ur timing advance it possibly check out fuel filter then it may be the fuel pump can be alot of things ive went threw it all last month

 

my friend had this prob and so have i take out your fuel rail and you can buy this cleaner to spray down your injectors real well put it back in and that should work its a real simple fix if thats your prob 90% sure thats your prob man! try it and see if that dosnt work then try out your other ideas! but this is a easy check! hope i helped i just found this forum so im a little late on your post sorry!

from the last time i was doing a search before doing a swap on my civic dx hatchback.......i was thinking of doing a ZC. i was getting all the info i needed and i believe i saw one part that said use a 42-45 psi fuel pressure regulator. i just managed to do a 94 SOHC vtec swap on my car....due to emission/smog in california. ZC's here in california are illegal.

i'm about to buy me a brand new fuel pressure regulator for my SOHC vtec...cause the one i'm using....its off of my friends CRX 90 and i think i'm not getting enough fuel at the right time.

i'll let you know civicboyzc if that helps. i'm about to purchase one first thing in the morning before i go to work tomorrow. another thing...what psi fuel pressure are you getting??@civicboyzc??

 

Hey vsual im not sure i really should check installed my si injectors last night they were dirty so i added some cleaner im gonna see how it doesn in the morning

 

Good luck i'm about to go and purchase me a brand new fpr and install it tonight. i'll let you know if that helps. keep me updated too about the injectors.

 

Hey guys after replacing. Fuel filter, egr valve, plugs, plug wires, coil, ignitor, cap, rotor, injectors, fuel pressure regulator. It still bogs but when i turn on the car from a cold start it has alot of power for about 1 min are so and shorty after i get boggen i think i may be loosesn fuel pressure or not getting enough fuel pressure

 

damn! same situation here!!! but i never purchased me a new fuel pressure regulator.

the pepboys wanted to charge me $117.99 for a 94 SOHC vtec fpr. the dealer was charging me $130. i said what the f@$**@$K??? cant afford that. the fuel pump is cheaper than that damn fpr. i guess i have to purchase me a fuel pump ....but not right now. no money...hehehehe..spent it all for Christmas.

civicboyzc....are you thinking what i'm thinking?? by replacing and cleaning everything....there's one thing we havent checked or replaced....hehehhehehe.

 

if ur buying it ur buying it for that much buy the aem adjustable fpr its 150
