02silverpathy Posted August 29, 2006 Share Posted August 29, 2006 Hi guys, as you know I have been battling my path to run like a thoroughbred. I have discovered that there are many of my vaccuum lines messed up...yep should have done all the work myself If anybody out there can provide information based off of the pic I have posted it would be greatly appreciated. Inside the coroded piece of metal is a small vacuum solenoid...could you please tell me where your lines run to? I am in need of this info. I have found that the EGBP soleonoid (backpressure solenoid) was incorrectly vaccumed as well as the EGRBP valve was unhooked from its line all together. This has cause great havock to the engine, hopefully no damage. I say this because the EGR can allow more air into the engine whenever it gets the correct temp and vac (?) so I am guessing this is why the engine is running so lean---likewise after all of this is routed correctly (minus the above), the EGR valve flutters instead of a solid rise and fall unless it is under extreme acceleration.... a new EGR will be here for me on thursday!!! :secret: psst the dealer was 2nd to the cheapest for this part!! $167 with new gaskets!!

vengeful Posted August 29, 2006 Share Posted August 29, 2006 Here's a capture from the FSM on the vac line routing. I'll take a picture of the actual setup when I get home. Link to comment Share on other sites More sharing options...

I have discovered that there are many of my vaccuum lines messed up...yep should have done all the work myself So all of your problems post-cam-install have been from disconnected vacuum lines, not from the cams themselves?

02silverpathy Posted August 29, 2006 Author Share Posted August 29, 2006 Venge your pic looks more like my underhood...minus the throttle opener. I do have the vacuum port under my TB like in XPLOX4's pic though---what the H? Link to comment Share on other sites More sharing options...
vengeful Posted August 29, 2006 Share Posted August 29, 2006 The systems changed quite a bit from year to year on the early R50s. Download the 98 FSM from the Phatg20 site - and it should be identical. The one I posted was from 1999, the one on Dean's site, I presume, is for a 1997.

XPLORx4 Posted August 29, 2006 Share Posted August 29, 2006 Like vengeful said, the vacuum line routing, sensors, etc. varied a lot in the early models. A 96 is way different than a 97. For example, 96's EVAP canister is IN THE ENGINE COMPARTMENT. 97 vacuum line routing is different than 98, and so forth. This was the early days in OBDII compliance. So, yeah, my service manual is for a 97, so it won't necessarily look like your 98. Link to comment Share on other sites More sharing options...
