intermittent operation of main butterfly

[coolbigrock]

hello to all,i am having a problem with zd30,intermittent of the main butterfly,sometimes when i turn off the engine,it shuts down smoothly,other times rough,i have check the manual and followed the process of troubling shooting the cause,the ecm relay is good,the connections,the vacuum, solenoid,fuses are good.what gives?

connect a light bulb to the solenoid or a vac gauge to see if its actually being triggered.
you could have engine run on from oil in the intake.

no oil intake,i have a catch can for that,going to the electrician this weekend to get it sort,will let ppl know the outcome.
