alrite well i wasnt sure if i should post this because i dont think anyone can help me at this point, after hours of searching and troubleshooting i am sick to my stomach and beg of your help. no to start of i will explain how it all went down. one night i decide to take my car on the highway and do some pulls, well i only got to do one, i launched my car and it hauld *** and i mean it really pulled hard. well i got too 5th gear at about 120-125 and the car lost power real bad and didnt wanna pull thru the rpms. at first i didnt think much till i tried to fix it, well i thru a wideband o2 on it and guess what, 12.5 at cruise and 10.9-11.5 at WOT. now this is a list of what i have and what is new. at first before the wideband i swore it was lean, which was true because a had a faulty o2, now with no o2 and the wideband it goes dumb rich.

check the top and there is a list of parts i replaced, not to mention i tried all the parts i replaced on a friends car and they worked flawless

 

please help

 

I'm no expert when it comes to diagnostics, but if I were you I'd check your compression, do a leak down, check spark plug gap, check fuel filters (even the ones in the injectors), and maybe tune it with the use of a wideban on a dyno... Just some thoughts.

 

iight but like i posted on the top i did all that.....compression is 250 all across!!!

 

ttt

 

ttt try checking your continuing transfuncktioner

 

that's what you get for putting a prelude motor in a crx .......j/k bump good luck

 

you said somewhere else you were using a stock p13. If that is the case and you jumped up your rail psi to 48 then that would explain your low afr's on a stock motor with stock ecu.
You didn't throw a cel when you pulled the stocker O2 sensor for the wideband? That would cause limp and rich conditions as well.

are these parts brand new or new as in from a different car? I would suspect your injectors might be stuck open. But if they are brand new then i don't know. And wheres your o2 sensor?

 

iight well i fixed the problem and now i wanna race

yes, from what he explained in another thread thats what happened...it must of been under a lot of stress, and prob real old.

 

haha really old try three months. the car is just such a beast im gonna go to the garage and get it

 

this is what made me miserable and change all those parts on the top for absolutley nothing

 

atleast u know ur ***** reliable and u don't have to worry about it. Thats weird, i never seen one like that in my life. I wonder how that happened? and its good u found the problem.

 

whoa.. thats freakin crazy. there is some backpressure for you..

 

damn 1st time i saw something like that....what made you look at that? lol

 

heard a slight leak, decided to fix it and what do you knoe
