ok, so i searched this, only to find Alot of people that didn't get there questions answer either.
so here goes, i'm throwing the codes 43 (fuel delivery), 41(primary oxygen sensor heater), and 1 (o2 sensor).

The problem is described like this, car cranks perfectly, drives fine, until i get on the hwy and up to speeds, then code comes on until i park the car again, then everytime, once i crank it, drives fine a few minutes, when i get up to speeds, code returns.
Now, the car boggs BAD when leaving a light or stop sign, even at half throttle, i have to floor it and when i do the power kicks in and car jumps and goes, so when i leave stops i have to floor it, if not i have a major loss in power.

i bought the car as a DD last fall, at that time o2 sensor head had broken off so i replaced it with a new one, and now i have these codes, i thought at first maybe it was my dizzy since the seals on it were bad on oil was dripping out the bottom of cap, so i replaced dizzy wednesday but that was not the problem- needed to be done anyways, so 43 throws me aloop, cause fuel system? thats a broad range, anyone have any ideas?

Only thoughts i have is try some seafoam, if that don't work, change fuel filter - haven't done yet and don't know when last time i was changed. any thoughts are greatly appreciated! Thanks peeps

 

Did you clear the codes after replacing the dizzy?
If not they will still be in the memory!

Code 43 is a very generic code. It can be caused by a bad o2 sensor(ad or wiring), incorrect mechanic timing, bad fuel injector, bad MAP sensor, bad fuel pressure regulator, clogged fuel filter, big vacuum leak. I would start with the O2 sensor and go from there, I would check the resistance from the connector at the sensor, to the connector at the ECU first. If you can get ahold of a factory honda manual, they have very detailed diagnostic trouble charts. I found some online a while back, but don't remember what site.

Hope this Helps.

 

well i actually have the entire factory manual on disk, my suspicions thus far are fuel filter, o2 sensor and fuel press regulator, but i'm gonna troubleshoot it later, it raining now , no garage...

 

ttt anyone else?

 

its starting to get worse, yesterday when i tried to leave, and its happened a few times since then, but when i leave a stop sign or a light i almost here what resembles a knocking noise, but more at a higher pitch, its hard to describe. i just really hate to end up replacing distributor, regulator, filters, injectors and not solve the problem.. Does anyone have an idea of what could cause this?

 

I have code 41, but the car drives fine. I get 32 mpg with check engine light on. I replaced my O2 sensor from autozone. It looks like the non-honda O2 sensor has a different heater resistance reading causing the fault. But code 41 will not cause it to bog down.

How many miles on the car? I have over 300k miles and I already replaced the ECU, TPS, spark plug wires, battery and ignition coil. That's about it. Other than that it still runs good.

 

my 90' has about 155k miles, orig motor, i replaced o2 sensor with autozone one (duralast?) in september of last year, but it always ran find until about 2 weeks ago.
