ok i got an 88 dx hatch that has an lsvtec in it and is converted to obd1. all the wiring is correct and has been redone more than once. it seems that is running rich in cyl. 4 because after I put in new spark plugs the fourth was covered in carbon and all black after like two miles. when i get on it it seems slow as hell. when i remove the spark wires from 1,2,3 the car bogs down a lot but when removed from four it barely makes a difference. now here is the wierd part.... when i remove the inj. clips from 1,2,3 it bogs down alot but if removed from four the car completely dies?.?.? wtf! ive changed injectors, ecu, clips, dizzy. the wires and spark plugs get spark and it sounds like injector 4 is working.
is it possible that some of the injectors are peak and hold instead of saturated like i need since i have no resistor box. i have obd0 injectors and clips??? and no resistor box?? is this a problem??
what do you guys think any help will be greatly appreciated.
thx in advance.

 

if they are obd0 injectors then there should be a resistor box. those injectors are supose to hold 3ohms if im not mistaken, someone correct me on this. u should change it to obd1 injectors and see if it makes a difference

 

If the box has been removed then you have to use obd1 injectors. it is possible that they are the wrong type. however obd0 clips will not fit on an obd1 injector, not without filing away the plastic tabs that get in the way inside the obd0 clips. i would check to see if the clips look like they've been augmented in any way. also look at the injector wiring where the box used to be and make sure its all still together. there are 4 red/black wires and 1 yellow/black wire. they should all be soldered or connected to one another somehow.

 

Please edit your thread title...

 

dunno how sorry but thanks for the help.

 

this new h-t makes me want to throw up I don't even like posting anymore... anyway..... check the resistance on all 4 injectors and make sure they are the same. if you have no resistor box then you want injectors that have between 9-15 OHM resistance. (They should run 10-12) also you need to do a compression check on all 4 cylinders and check that #4 injector carefully... it could have a bent/broken pintle causing it to spit erratically. I'd also say you might want to put a new spark plug in each plug wire and make sure that they spit clean spark by laying them on the head while cranking the engine and watching for good strong spark. Another check to perform is check your firing order against another honda that is running normally.... you could have #3 and #2 reversed or something. Good luck.
