car bucking/surging (idk) randomly while driving

The ignition is from acceleration smoothing. See http://www.hondata.com/help/kmanager/ge ... meters.htm

With the o2 sensor it could be the o2 sensor / wiring or just from the car not being tuned. I can't tell.

Can you give any insight on why my injectors stop from time to time? It isn't making any sense. The car ran great before the o2 went out drive it for a while with a bad o2 then it starts bucking. Put a new o2 in it hoping it would solve the problem but with no improvement.

I can only think of one thing that changed and that's I had a custom exhaust put on and they did some welding of the exhaust with it on the car I know k series are very sensitive to voltage could the welding have hurt anything electrical?

That is always a possibility. Another thing to consider is why the original sensor went bad. It could be a wiring fault somewhere.

The original o2 sensor would stop reading if after cranking the car initially the car sat and idled too long. If you revved it a little while the car was warming up it wouldn't kick a code though. If I remember correctly it would kick a o2 heater cel. Now granted I wasn't letting the o2 heat up initially prior to starting it but I do now.
