any one?

 

Maybe you should put all the D15 stuff on the motor like it was meant to have.

 

well i agree with tippyman. if you have the ecu and the jumper harness that's all you need. the ex is already mpfi and the only thing you need to change is the driver side motor mount. i had a 90 ex sedan but i love my 88 and have converted it to mpfi and obd1. if you need anymore help pm me or reply if you can't use pm

 

im just gonna buy a 91 long block and do it over...im not real good with the wires.. plus i always liked obd0 more ...thanx thoo and . jdm_ef3. i love how all does 4 doors look can any one join your crew or its a local thing..

 

you are more then welcome to join the ef sedan squad, just post some pix and a little about your 4g4d. keep me posted on your build!

 

uhh did you say that you are used the OBD0 dist with the OBD1 conversion? if you did, you need to use the OBD1 dist that will fix your problem

 

this is the thing i kept the obd0 set up but what i did is use my obd0 dizzy is ther a way to test a dizzy?i still have my obd1 dizzy with obd0 plugs but it wont start think i did the wires wrong....hate looking at my 4door just ther looks half dead...
