im of no help to your current question
but what car do you have?

yo
 

1989 civic HB si, with a d15b vtec swap, im pretty sure its out of a civic Vt-i

damn i was hoping it was a crx im trying to see if anyone else on here has a rex
but that looks like a nice EF you got you should post pics in the appearance section

ok
 

ok well i think im just gonna order a new distributor TD42U right? (d15b vtec) cuz i mean misfiring and i open the cap and dizzy is taking oil inside, im sure its messed up thats my only guess

ok
 

so let me add some more info, the iacv is jumpy, always has been dont mind, the car sat for ~3.5 weeks, i inspected the wires where they go into the valve cover and plug in, they look fine no archs, distributor has oil in it, probly the bearing going out, i dont think the sizzys have sensors in them so i dont think thats it, the car has been turned to (what a guy told me by looking at it) obd2 but i think hes wrong and its obd1 (didnt know u can make it obd2) the light threw a code up and after i turned it off it went away, that was twice, there are 2 wires blue and orange coming out of the ECU, is that where i jump to check my codes? i dont know where to check the codes because its been re-wires im assuming, well the origonal jumper is not there and i cant find one

they do they have a cps (camshaft position sensor) dpfi is the only ones who dont have it. and the 96 and up have it on the crank
