My '88 Fiero - The Never-Ending Saga

[GTRS Fiero]

Well, I hope these fit.

Judging by every listing image I've found, the axle you show as being the one you received for a left axle is for a manual transmission.  The left axle for an automatic has internal splines at the tripot end. 

[GTRS Fiero]

Joy.  My set had internal splines on the short axle.

The left axle did fit into the transmission.  Only the splines had an issue at the hub.

[GTRS Fiero]

The axles are in. They fit.  No more shaking.  That is the good news.

The bad news is that both sets were the exact same part numbers.

The plastic circuits in the instrument panel were shorting.  So, replaced the IP.  Moved all the gauges over, as well as the odometer.  Everything worked...sortof.  the e-brake light sometimes works.  When it stays on. Moving the lever up and down resets it.  The temp gauge seems to have different issues.

To get to the pushrod, the upper intake had to come off, including the fuel block.  The seals on the fuel block had deteriorated, so new seals were installed.  Not very impressed with the prior seals, which were green.  Maybe cyan.

Some of you may remember from the Fall tour that I wasn't happy with the loom for the EGR wiring.  Here is how the wiring looks, now:


Further back:


Now, I'm not happy with how the plug wires sit.

My keyless entry is now working, again.

[GTRS Fiero]

..and I got a citation from the gestapo!  Joy.

Does it make a difference which plug wire is next to which?

[Fierofool]

Sometimes it can on some engines.  A small block Chevy's 5 and 7 cylinders are on opposite strokes.  When 5 fires, 7 is just starting compression.  If 5 crossfires or the spark jumps inside the distributor, it can blow the wall out of 7.  The Fiero doesn't have that problem due to firing swapping back and forth between cylinder banks and no 2 cylinders that are side by side fire in sequence.

I'm not sure about DIS conversions because you have 'wasted spark' with 2 cylinders firing at once.

[GTRS Fiero]

The plug wire routing is a bit better, now, and the black grime has been scrubbed off:


Unfortunately, that nice new loom that was just put in is now just as melted as the loom it replaced:


Very frustrating!  There is some loom in the engine bay that seems to be impervious to the engine bay temperatures, but this stuff melts at the thought of engine bay temperatures!  Maybe I need some better loom.

[Fierofool]

There is loom cover that's specifically made to withstand engine bay temperatures.  Most likely what you have there is the type used in the interior wiring.

Something like this. Good to 247°F
