it seems to idle fine right at 950 im going to check for leaks but i dont think there is any.

Re: stumbling zc??
 

back to your original thought....its probably the o2. I have a bad o2 right now w/ the bad o2 code. Idles ok....goes kinda weird when warm. When I drive the car...it'll drive ok under normal conditions. Once I punch it a bit....it'll start stuttering. But if you slowly let it go up the rpms....it'll go up fine. I know its dumping fuel like crazy. So....if you have another 02....swap it. Then let us know.

holly ------- ----!!! thats it. yea my ---- does same thing.i got some vids of it if i can figure out how to post them up i will.yea i think i need new o2 sensor im pretty sure this one seen better days.it came off stock dx mani (89) civic

Re: stumbling zc??
 

UPDATE!!!!!!!!!


i got another o2 sensor and put it in,it still does it anybody got any other ideal on what could be the prob??

and today i went to see if it would studder well i went to do a small burn out and the cel came on and the car shut off.now when i try to strat it it wont start,the main realy dont click fuel pump dont prime and the light on the ecu does blink.what im going to do is try to change the main relay with a knowen good one and see what happens.correct me if im wrong but if the main relay is blowen the car shouldnt get spark right?

Just an idea but have you looked into a bad TPS? I have a weird stutter in 4th and 5th but just under normal driving. I feather it a little bit or drop down a gear and it goes away... ::)
