i have recently swaped a h23a1 into my 92 civic cx. but it is a bitch to drive. i have the stock(prelude) fuel rail, injectors, pressure regulator,and feul pump. but my gas pedal seems like it isn't working right. it idles fine, butwhen i floor it it will cut off. if i don't give it enough than it will just sit like it's idle. no matter what gear if i don't push it just right than it won't do any thing. but if i hit the spot it accelerates. just wondering what it could be. i am running the civic throttle cable. but i have the lude cable, just wondering what i should do from here. oh the air fuel guage reads lean when this is occoring. at idle it's normal and when i hit the right spot it's normal too. please help! sorry for the long post.

 

I have the same problem with my Teg, but I have never fixed the problem.

Some things you may want to check out and probably need to be replaced anyway:

Fuel Filter
Plugs
Wires
Check Timing
PCV Valve?

I have replaced them all to no avail, but I may have a different problem than you do. Also look into testing your 02 sensor.

 

done them all just like u no fix. i really need help! i can't drive the car it is so bad and i just finished the swap.

 

It could be alot of things. But first check all your Distributor components that will cause a bad hesitation! Also your 02 sensor. If that dosen't work i would upgrade your fuel system? maybe not enough being flowed to the motor like PSI? Fuel pressure regulator and fuel rail would do.

 

is your ECU throwing codes?

 

yes a fuel system code 43
