Does this look right to yall? Trying to troubleshoot my vacuum leak still. Thanks a million guys.

 

...minus the purge solenoid. Looks like there wasn't one in '94 on non-Cali models. Hopefully the rest is correct.

 

rather then go insane chasing a vac leak make a smoke machine. its very easy and will save you a ton of time. all you need is a source of air pressure, container and smoke source.
now if your a smoker then you are your own smoke machine. take a vac line off, take a drag, then blow it into the lines (with engine off) till you see smoke come out...wont take long. there done and done.
now if you not a smoker then you need to redneck it like i did.

hope that helps ya.

 

i always thought that line on the bottom of the 3 way went to the transmission. I may be wrong on that one...

I've been reading your posts, have you done a fuel pressure and leakdown test? That seems to be 90% of idle problems

 

I replaced the fuel spider with a brand new AC Delco. I've not tested it because I thought surely that can't be it. But I guess I better check it too.

I didn't know there we're any vent/vacuum lines that went to the tranny, got any diagrams I could us on that?

Thanks for all your help.

 

ok, so you are right, the line is for the EVAP. Idk where i got the info to make me think it was for the trans.

If fuel pressure and leakdown check out the next step is to check the egr valve for gunk in it. or a nice chuck o carbon.

 

here ya go... hope these help out some!

 

Thanks, that does help.

 

Doing the leak down check today. Got a new ACDelco EGR already in it, but I'll probably have to look again.
