i got a 91 honda civic with d15b2 i reently did the 4 dpfi to mpfi conversion and since then it bogs out at low rpms i tried change fuel filter and still same problem i do got an ls fuel rail on it idk if thats a problelm..does any1 have any idea what i should check?

 

Do u have a stock cat on it and maybe a code do u have engine lite on?

 

i emptyed out the cat...no check engine light tho
also i forgot to mention when stopped sometimes it idles a bit

 

Do u think u have a leak somewhere maybe

 

idk..it was running good before i did the mpfi conversion you think it has anything to do with the dizzy?

 

I dont think so as long as the spark pattern is the same

 

questions:

1) Does it happen when the engine is cold - yes or no?
2) Does it clear up the moment you go over 2500 rpm?
3) Does it happen when leaving from a stop?

 

check your timing and also to your wiring you did for the dizzy and make sure its correct

 

when its cold it bogs out more...
when i pump gas it runs good when i take of then starts bogin out again..
