I got my B18C in my Eg , finally i got it started. The O2 sensor isnt connected and there is a little vacuum nipple on the firewall side of the throttle body that i cant find where to plug anything to.

When the motor first got in the car it wouldnt start so we checked to see if it was getting spark and it wasnt so we changed the coil in the distributor. But then to realise it wasnt. The ECU light was burning dim and we couldnt figure out why. then i remembered that the O2 sensor wires had come out of connector housing and i just just pushed them back in... yeah i kno quite dumb. so i pulled them back out and the car started.

but then i tried setting the timing and the timing marks werent steady the were fluctuating from about 8 degrees advance to about 20 advance. and no matter what i cant seem to stablise it. the car is also idling high but i think that is from the open vacuum nipple on the throttle body.

Whatt can be causing the timing to jump around like that ? how can i fix it?

 

your idle speed is high and probably fluctuating which is causing the timing to jump around. You need to stabalize the idle first, so plug your O2 sensor in, plug the nipple off on the intake manifold if you don't know where it goes (probably to a cruise control). Once you do all that, take a paper clip and bend it into a "U" shape and stick it into the service connector like it shown in your manual. Now start the car and see where it's idling at, it should be down around 750-800 rpm ideally. If it's not, you may need to adjust your idle speed first so follow your manuals intructions on how to do so. Then set your timing to 16 degrees.

 

I think my distributor isnt working too well ..... the car is sputtering and i just started it and the timing isnt jumping around as badly .

My O2 sensor has 4 wires ( 2 black , Green and white ) where it connects to the wires arent the same colors, they is a black , and orange and something else. i looked at them last night but i cant remember the colors. if anyone can guide me on which color goes to which that would be appreciated

any ideas on how exactly i can stabilize my idle?

 

well it could be vacuum leaks, fast idle thermal valve, idle air control valve, or throttle position sensor.

 

i got it started....and holding idle .... i checked fuel pressure and realised the car was bleeding off the fuel pressure quickly. if i started the car and then turned it off, in 5 mins or less the car was reading 0 psi .

so i swapped out the pressure regulator and the vacuum lines and tried again and it works.

 

ok i got it started but the idle is still irratic. it bounces up and down. and with the timing light connected i can see that it is misfiring. i install the old coil and the it seemed to idle more stable but every 15-20 secs it misfires and bogs then picks back up. Then if i put the other coil in the distributor then it idles irratic again.
could there be something else in the distributor that is bad that causes this when i swap the inition coil?
