Okay, I think I'm done on this one and throwing in the towel. I've been going through the vacuum lines for over three months. I know that seems long but finding an accurate 1.7L FI California carb diagram has been like trying to find the Holy Grail. I had help from Jeff B. and put the best two diagrams together in an effort to clean things up in my engine bay.
I purchased my '72 1.7L back in April and when I first started it there was rough idle as expected but it revved. Once I started replacing the old vacuum lines I must have reversed some lines because that's when the problem started. The car starts right up and has good idle around 2500 then drops just above 1K so I believe the cold start and AAR are working fine. When I manually open up the throttle, the engine bogs, and the rpm's drop. It's as if there engine is starving for air and doing the exact opposite when throttle is opened. I went ahead and purchased and installed 914rubbers 1.7L TPS board and there was absolutely no change. I also rerouted some of my vacuum lines again to where I believe they are spot on. Could the problem be my MPS or possibly Decel Valve? Anyone near the Chino Hills area this weekend? My goal is to get her off jack stands this weekend! I would love to try someone else's MPS or Decel to help me in my process of elimination. (IMG:style_emoticons/default/headbang.gif) |
