Hello,

A few issues on my recently purchased '94 Tsuru (mexico)

1) I cannot find the correct factory service manual. Even though it has the B13/Sentra body, it has the E16 fuel injected engine.

2) When bought, it had a little hesitation when you floor it, but nothing I thought a little tuning wouldn't fix. But it has gotten worse and seems to be getting poorer and poorer mileage. It starts fine. I checked the ignition system, seems to be okay. The plugs look clean. I cleaned the throttle body. I suspected a vacuum leak or a problem with the emissions equipment (EGR, etc.) so I did some more checking and found 2 things:




First, a disconnected hose. I am not sure what this thing is called, pardon my ignorance. Don't know if this was like this when purchased or if it fell off subsequently. Naturally, I reattached the hose, but have not test driven yet because the entire assembly is "free-floating" and do not want to risk although I started the motor and it seems a little better:



So my questions are:

a) what is this thing?
b) where/how do I reattach this thing?

3) Any other ideas on the sluggishness/hesitation? I plan on changing fuel filter. Would like manual first though...

Thanks,
jnr

doing more research, appears to be the Backpressure Transducer (BPT) that is floating there...

more info... what the Tsuru seems to be is E16i engine with GA16i fuel injection system identical to attached diagram from autozone.com (useful site by the way). what I would really appreciate is if someone could take a photo of their BPT valve and how it is attached to the engine/manifolds/whatever.



Thanks,
jnr
