Ok, I dropped a Y8 in my 90 DX CRX. I wired it to multi poin OD-0 using a ZC ECU. I finally got it dropped and the car to turn on. but it runs like straight ass. it wont go past 2100 RPM and dies out and sputters. I changed the spark plugs, wires. Dist. fuel pump cleaned the lines. fuel filter. .. still runs like ass. is there any other things that you think could be wrong? vacuume leak? FPR? I really have no idea anymore. I am by no means that great with cars. any ideas or anything is appreciated. thanks.

 

is it throwing any CEL codes

 

Yeah, it is just checked. I dont know what it means... I will search. but it to short blinks and then a long one.

 

I take that back it is blinking like fucking crazy. one is 10 short blinks I think and one is 7 short blinks... I dont know how to check the codes. just killed my third battery too

check the codes there

sounds like you didnt convert the harness to mpfi correctly.

 

may want to try a pm6 or pr4 ecu as well. or at best a pr3 or pwo so you can wire up your vtec properly.

 

i got a pm6 u can try.

edit: also check your tps and see if u cracked it or broke n e thing on it. also what MAP sensor are u using?

thanks guys, looks like I gotta go get an ECU most likely. checked my MPFI wiring. did just like it said. it is pretty straight foward. to wire it up with VTEC dont I have to wire to OBD-1 this is the first swap I have ever done so I dont really know that much. gonna check my grounds and all that stupid shit one more time and see if I have any luck before I go spend anymore money.

 

if you get a pr3 or pwo ecu you wont have to go obd1 these are both obd0 vtec ecu's

 

I am using the MAP on the firewall. yeah it is throwing the TPS code but it is plugged in and looks fine to me.. plus I was looking that the engine just a sec ago to check all the connections.. the alt. wasnt hooked up all the way. wanna check it now but I gotta wait on a jump... I have 3 dead batteries.
