Hello ppl
*newbie 2 This Forum

ok the car is a 91 si with a sohc zc on a pm6 ecu i had to re wire the injectors to the o.g. si harness i used a set off a 92-95 civic not sure what model? the cars seems to be run perfect at idle and and normal everyday driving(alittle jerk around 3000 rpm's) but when i put my foot in it will feel good up to about 4.5-5000 rpms then just feels terrible no power what so ever just roaring but no pull/power and if i let off the gas its as if the car is off rpms dropping fast comes to a complete stop start car again little bounce in the idle and then it sounds good again im only getting one code right now and thats (9) CYP (Cylinder) -[Defective circuit or unplugged/ Defective sensor] cause it is cut off the harness but pretty sure thats not whats causing this to happ. thow now more detail bout the motor it has intake/header/exaust/strait pipe besided that pretty much stock motor-wise oh yea one last thing i forgot it has some bounce in idle when just sitting for a long period of time 5 min + will drop low and come back to normal

im think the injectors maybe?

 

it can be a number of things.

check:
Injectors-u do have resistor box right?
Distributor-coil might be going bad- happened to me
main relay-they tend to go bad

are you running your car obd0 or obd1?

 

pics wouldn't hurt either

 

resistor box is connected and working if unplugged just cranks the dizzy is a rebuilt but i think its off a dohc zc not sure buddy of mine let me get it?
and the main relay i cant even say i know where to find it or anything a little stuck on stupid right now

ill get pic up in just a min

 

the code 9 will cause all of the headaches you are encountering. the dohc zc distributor will not work correctly because it is missing that crucial sensor. you need the si distributor to make it work correctly.

 

you beat me to it.

 

you def gotta change the dizzy or sort the wiring to it. also you typing is very confusing. you arent trying to use 0bd1 injectors with a resistor box are you? that doesnt work

 

alright my bad on typos but it must be from a si(d16a6) to work correctly or can it be from a dpfi motor as well

 

u might have a obd1 dizzy and your trying to to re wire it to the stock harness..whats the code on the dizzy? is it TD-01 or TD-02? or difrrent?

 

td-02
