Well here is my dilemma I have A 92 Civic VX H/B and The motor studers and jerks around soon as it warms up,the only code it is throughing is o2 but it takes a 5wire and I can almost get a dohc for the price of it.But would that be the thing messing it up it feels like fuel stuter,some one said it could be the egr valve,I have replaced injectors,dist,wires,plugs,map,tp,pvc valve just need to get it running till I get more money for dohc so if any one knows please let me know,thanks so much Isaac

 

simple logic would be to fix the code you have.the O2 sensor is important to proper operation of the motor.

well my car kind of does this also, but im not throwing any codes. but before you replaced anything i would have replaced the o2 censor. the mechanic i took it to told me that it is something in the ignition. do you have aftermarket spark plug wires or a bad cap/rotor?

 

well I wanted avoid the o2 so I could get some more cash to buy my b18,I never thought of the cap/button it has A new dist.its weird it will run till warmed up then sputer then if you press in the gas it dies.

 

What kinda of plugs did you use? Stay away from gimmick plugs like Bosch Platinum +2 +4 and split fires. The extra electrodes act like a wall a don't allow complete combustion and create a stuttering type of miss. Unfortunatly I know this from experience NGK is the only way and they don't have to be platinums or iridiums either. I only use Copper plugs in my vehicles the bigger electrode allows more spark energy to jump the gap. They may not last as long but they are way cheaper and a spark plug tells a good story when read correctly. As far as the O2 sensor goes, I would've replaced that first and followed with everything else you did just as basic preventative maintainece!
