this is my daily driver and i need to get it up and running
i have a dohc zc in a 91 hf crx
when i drive the car it runs fine and when i start the car it runs fine but when i am driving and i down shift or stop ant a light it putters and slowly dies?
i have a new fuel filter and a new fuel pump so i don't think that's why it messing up it seems to me that it is flooding out and my mouth old spark plugs look pretty black
it was throwing a code 1 and 9
9 is the cyp so i looked it up in my maul and it said it was a censer in the dizzy so i replace that but it still runs like this
I HAVE NO CLUE WHAT IS GOING ON!
some times it runs fine but most the time it runs like ****.

 

If you have a DOHC ZC the CPS is not in the dizzy, it's on the front dizzy side of the valve cover.

Edit: I think that's where teh CPS is, it's been a looong time since I've had my EF......

 

i was thinking it may be on the exhaulst cam censer but i thought a code 9 was the CYP

 

whats code 1... map ? that'd do it.

 

code 1 is 02 sensor.....and check the voltage to the map sensor....mine used to do that....the ground to the sensor was faulty

 

Bad TPS maybe? Have you checked all your grounds? Have you done a compression or leakdown test? No vaccuum leaks on the TB? - Darrell

 

yes code 9 is the cyp, or what ever. but its on the exhaust cam. you should have taken to wires from your dist. and ran to that sensor. Is that how its done?

 

Does the code 9 set as soon as you start the car?? if so probably caused by wiring or sensor failure
BUT code 9 on a ZC CAN be caused by timing belt misalignment. Mine was off by a tooth and would only set the code under certain driving conditions. timing belt alignment may also explain stalling condition

 

okay h-t check it out my Eng. is flooding at times it wont do it if its just sitting there but it dose it when i am driving.
this is what i don't get when my car is messing up and flooding trying to die i have no fuel pressure but the Eng is getting to much fuel ???
