Hi Guys, so I am asking another question and hoping to not get burnt to a crisp. The reason I am asking is, in my other thread a question was asked about a 2nd connector down near the VSV for FPU. My answer was that it must be the connector for the VSV for egr. Now, I was taking a very close look at my car to compare with the diagrams. The diagrams show 2 vsv's, 1 for the fpu, and the other for the egr. So here's my problem. I do not have a second vsv. I searched every where in that area for another vsv, under alternator, back on firewall, under intake plenum. I used flashlight and a mirror to see under everything I could. There is no 2nd vsv there, and there is no 2nd connector, or capped off vac lines. The way my system is plumbed is as follows.
Vac line on Fuel Presure Reg goes to metal pipe, pipe goes to rubber hose , hose goes to output nipple on vsv for fpu, input nipple on vsv for fpu has hose attached, hose goes to pipe, pipe goes to rubber hose, hose goes to nipple on egr modulator, other nipple on egr modulator has hose attached to it, that hose goes down to egr valve. No other vac lines that I can see on that system.
There is 1 connector that goes from harness to vsv for fpu.
Is this the way this car is supposed to be plumbed, it doesn't match the online service manual, but that is not for an 87, don't know if there is a difference between years.
And where is the vsv for fpu getting it's vacuum, if it is going to the egr modulator, and that ends in the egr valve. Does the egr valve supply the vacuum?
Really appreciate anyone that can explain why my car doesn't match the diagrams, and how the egr system can work right with this setup.
