The IAC has been replaced twice in the last year, including the last time, which was 3 weeks sgo.

Replaced the IAC, again.  No change.

Replaced the O2 sensor.  Oddly, that made the rich issue worse.  So, I guess I'll put the old sensor back in.

Yes, but it's been a while since I did one (way back when I had my red SE), and I can't remember a lot of the details. I do remember that you have to be very careful tightening one of the bolts.

Very careful....?  Not to cross-thread?  Not to over-tighten?  Not to catch something?

Not to over tighten. There is air beneath one of the bolt holes, and if you over tighten, you'll break your brand new water pump. Most come with a warning sheet about that in the box.

Replaced some sensors.  My Fiero was ready to go for a test drive...but it's hailing.  Maybe another day.

The hail quit, so I went for a drive.

Here is the new VSS, as received:


With a bit of elbow grease, it looks a bit better:


The speedo is still 10 MPH off.  >:(

The new VSS gear does have an additional tooth.

Now on to my water pump.  I think it's bad.  Here is my reasoning.  It tends to get hot when the RPMs are higher, but stays cool when at lower RPMs--even through stop-and-go traffic.

If the coolant is getting hot, I can shut off the engine, and restart, and it will cool off, for as long as I run lower RPMs.  Basically, at idle.

Since the water pump is driven by the engine, the higher the RPMs, the faster the water pump turns.

I believe I have one with a plastic impeller, and the impeller is loose on the shaft.

Of course, the proof is in the pudding, but is my reasoning sound?  I don't want to replace the water pump for nothing.

I have checked by pulling the belt and the hose from the pump so I can reach in and try to hold the impeller and turning the pully. If it moves then it is loose on the shaft.

The impeller would be inaccessible when the pump is installed.  How do you do that?  Remove the pipe plug or pipe nipple?

Last one I checked that way I used a plastic pry tool through the outlet and pressed it into one of the holes in the portion of the impeller that was visible. Wasn't on a fiero though. Was on a Camaro 3.4 if I remember correctly.

Probably easier to just replace the pump.
