stumbling zc??
ok guys i got a bit of a problem here.i got a dohc zc in a 91 crx si and when i punch it it seems to sputter really bad.the only cel that comes up is a o2 code.now my question is could a bad o2 sensor make my motor run that way?it will stumble realy bad then at times it will stmble then just seem to jerk a tad then runs fine then seems to stumble again.any help on this would be great.

my pressure is set at 40 psi even at idle,i really dont think fuel prssure is the prob.i think the o2 is going bad and isnt choosing the correct a/f ratio.<<this is just s threoy i have)and i thought i would post up to try to get somemore insight on what it could be.i know it cant be nuttin major or my car would be throwing more then just o2 code.

no i didnt do nuttin to the motor.its not boosted my tach doesnt jump it just seems to stuble on itself like its not getting any gas ill try my best to get a vid tomroow.like i said it must be something simple that i have overlooked.keep throwing me out ---- to try and ill give it a shot.
now check this out if i put a chiped ecu in there and run the perect pm7 bin it wont do it.but if i put the stock pm7 back in there it starts again,but when i first did the swap i used the same pm7 and it didnt do it till about a month ago.i would run a chip computer but i dont have one i sell them to quick.
