hey i got this motor from a friend and and i got it in and all that but when i start it sounds like it just wants to stall ,its throwing to codes 9, and 21 and i dont know what they are plz help

 

SOHC ZC or DOHC ZC? OBD0 or OBD1? VTEC or non-VTEC?

 

its a 1987 zc dohc non vtec obd0 , i found out that i had a vtec cumputer so i switched it to a pm6 and i still have the code 9 and i dont know wut that is

 

Needs a new dizzy

 

i just bought it on criagslist down philly it is new still in the box to

 

code 9 is the cylinder sensor - on the OBD0 DOHC ZC or D16A1, the cylinder sensor is not in the distributor - it is on the end of the exhaust camshaft - usually, a code 9 is either incorrect camshaft timing or a problem with the cylinder sensor wiring - the cylinder sensor itself going bad would be extremely rare

 

i looked at the wiring and every thing is good , so do u think i should go buy a crank sensor?

 

Have you checked the timing?

 

yeah i looked at the timming and every thing is right

 

i would try switching the 2 wires at the cylinder sensor

 

still throws the same code 9 again

 

wait do u mean cutting the 2 wires then putting them to the other wires??
