Default Re: White Smog Can't Catch a break

I'm not understanding what you are trying to describe as the "clips". Maybe post a picture?

There is really no substitute for using a gauge to check fuel pressure. Pressure could be too high and the engine would start easily, but may idle poor...

In fact, I believe the FP could also be too low (when engine is running) and the engine would still fire up nicely.

Wouldnít those situations show up in the LTFT and trip the dredded 0171 or 0172 P code?

Sure, FP could set one of those codes; but they could also be set by several other things. If you get one of those codes, you still have no handle on whether FP is OK

I am probably not using the correct name... The clip/wires there are three one for the idle air control valve, one for the throttle position sensor, there is one right below those two. When we took the the throttle body off the car, the sensor that I am asking about was still on the engine...

I will upload a pic asap...

I think there are two sensors that are roughly below the TB: the CKP sensor and the VSS sensor. They are both 2-wire connectors, but the wires will be different colors. If you can't get a picture, tell us the wire colors.

GUYS Thank You all for your help.... The Saturn now belongs to my brother (we plan to fix it without the urgency and time crunch)

I lost the stress of trying to keep it running being our only car... We bought a newer car, Chevy Equinox.... Better ride,power etc, but I will still miss driving the Saturn everyday...

Again Thank you ALL

Just wanted to comment-

One occasion, my '97 was idling for a while, longer than normal
(engine had been driven to inspection station, and were talking
for a bit) and, it (the exhaust stream) gradually began emitting
STEAM. I did not quite figure it out (cool spring day, humid).

It never repeated. After i drove off, the steam stream shrank
and ceased.
