i've got a TPI 305 from an 86 camaro in my nissan. it's up and running, i've got the timing, minimum air and TPS set. i have a pretty good little skip/miss at idle and the idle fluctuates a couple hundred RPMs. i'd like to check the codes if it's kicking out any, but i don't have a SES light at all. i've been looking for a diagram that'll show me where the wire is for the ses light. does anybody know how to wire up the light so that it'll work properly? i didn't do the swap myself so i'm not familiar with the wiring at the ecm side of the swap, but i've been doing alot of cleaning up under the hood so i know where all that stuff is.

thanks for any help,

ok, i figured out how to find the light. i'm getting a code 12....not just the first 3, it keeps on going with the 12. i found somewhere that it means no reference pulses. so, what are those and where do they come from?

 

code 12 means all is well

 

Aye, code 12 = good to go!

Well, quite obviously something is wrong if the idle is fluctuating up and down and there is a miss.

 

yeah, i finally got a 33, 36 and 44. i did some partial troubleshooting friday but didn't find exactly what the problem was. i need to get a digital meter so i can check the maf output, but i know it has power and grounds. i think the O2 sensor is due to the exhaust being incomlete. maybe the boss will approve getting the exhaust done soon.
