Car runs horribly at take off seems to sputter fuel. Smells rich. On a hill it tends to not want to crank. Any opinions would be highly appreciated. Changed out fuel filter and plugs are all good along with wires new dizzy and a new o2 sensor.

 

OBD0 shouldn't throw code 43, it wasn't implemented until OBD1.

How are you counting the CEL?

 

Are you sure it's not 4 and 3?

 

ZC is right, sounds like code 4 and 3. Which would be MAP. And your symptoms sound correct.

 

^ exactly

 

nope its obd0 pr4 4 paused blinks then three upon the 4 pauses right after not two different.

 

well my buddies car just had a bad map and his ran nowhere near like mine replaced it all is good now.

 

OBD0 ecu's have single blinks....there's no multiplying by ten or anything.....if there's 4 blinks that's code 4, three more after that is code 3.

80 EGR Valve/Line
86 ECT sensor - Cooling System
91 Fuel Tank pressure sensor
92 EVAP Solenoid/Valve/Vacuum Lines

 

so much wrong information .....

 

Code 43 is only thrown by OBD1 ECUs, and is exclusive to the Civic/Del Sol/Accord/Prelude platforms, Integra ECU throwing code 43 even being OBD1 would theoretically be impossible.

There is NO OBD0 code 43. OBD0 has no codes past 20.

For clarification:

Code 43
--------------------
Accord 90-95
Civic 92-95
CRV n/a
CRX n/a
Del Sol 93-95
Odyssey 95
Prelude 90-95
--------------------
Fuel Supply System
defective or malfunctioning fuel supply system

 

Well put new ecu in less stuttering no solid blinks and three anymore only code 9. It is a new dizzy guess I need another one.

 

code 9 is for your timing.....is you're mechanical timing correct?

 

Yep tdc timing marks all line up

 

Cyp sensor choice is within the dizzy I thought?

 

if OBD0 doesnt have a code 43 then how did i get this?

btw, what you listed was a HONDA category. If you had looked at a Acura section (b18a1) you would find it.


So many wrong information has gone through honda-tech and into others car.
DONT THINK, KNOW.

 

I was gonna say, I had a code 43 before when I fist swapped in an LS in my crx years ago. Turned out I had an open in the wiring for the fuel pump under the storage thing

 

Yeah cyp is in the dizzy except for OBD0 DOHC ZC's

 

This has been covered extensively many times before... It really helps to search...

https://honda-tech.com/forums/honda-crx-ef-civic-1988-1991-3/unexplained-codes-3014835/

Also, LOL at no code 43 on Acuras or OBD-0. "Bradley", you post a lot of misinformation quite often.

 

It was funny had code 9 on my old dohc zc obd0 and it was my dizzy

 

I'm sorry, you're right I'm wrong....I must've read it wrong earlier today. It's the CPS that's on the exhaust cam.

 

Correct sir

 

I never post incorrect information, I simply didn't know there was a code 43 on OBD0, had never seen it nor heard about it before. I did some searching and most people rule it out to be the FPR taking a crap on them *shrug* but it appears to happen RARELY.

This is the only time I recall "posting incorrect information". You need to quit calling someone out for something when you don't know them very well.

There is a reason he posted it here -- to get everyone's opinion, not just mine. That's why forums have hundreds of users.

 

Oh? Then what is this? You do this quite often.


Have fun!

 

stop antagonizing people. if you have a problem, correct the info and move on. if it's a personal problem with his posting habits, PM him and/or be prepared to prove what you are accusing him of because he is disputing your claims.

thanks.
