I have a 94 s-10 blzr 4x4 and saw a post about 4x4 and vaccum hoses were mentioned. Are there any that could come loose around distributor area where I was working ? Replaced cap, rotor etc. 4x4 does not engage all the way but I can hear it trying to but not the regular sound I normally hear. Could I have unplugged something back there or anywhere else while I was lying across the eng. compartment? Need my 4x4, have STEEP ICEY DRIVEWAY IN CENTRAL IL.!!!!!!!!!!!!!!!!!!!

 

If it is the Vortec engine then the main vacuum feed is right off the upper right rear corner of the upper intake plenum. One short piece of approx. 1/4" line goes to a vacuum pot that splits 4 ways. My short 1/4" hose was shot as well as the 5/32" hoses running to the vacumm canistor and the Cruise control.

 

Thanks alot 93LT I just noticed this trying to get up my drive and you mentioned cruise control and then I remembered on way home from work it did not work, so I thought I would check that out at daylight. So I think ya got it covered!!!!! Ya think??????? THANKS for quick reply.

 

My leak wasn't enough to bother the differential, but the cruise didn't have enough suction to maintain speed up a grade and my converter would jerk in and out at highway speeds. My guess is your main point of connection is probably not even hooked up.

 

I got your PM, I tried to return the PM but got the message you couldn;t receive or chose not to receive PMs. I was wanting to know if you had push button or floor shift 4wd.

 

push button I put up another post so maybe you can look at that i tried to change my e-mail and prefrecences but it would not work so!!!!!!!
