Hey guys, really need some help here, 2 questions...first

The 5 speed shifter from Fiero store, i bought one brand new from the store...had my tranny ppl adjust the cables on the tranny side and cotter pins...but the shifter is still stiffish and it doesnt bounce back to a nice neutral position...the guy thought i was missing some pring or springs? can anyone confirm if there is extra hardware i need for the 5 speed shifter?

2) My engine seems to be running a little ruff...and my power is not what it should be...i feel like there is more of a time gap between engine sparks? Almost like a diesle engine sound...i do have an engine light on, i will check it later. Im worried that one of my cylinders might not be firing...i had my mechanic take a quick look...and my ignition timing and distributor firing order are all correct...(also my engine sounds a little meaner than i remember) Can anyone suggest anything to check for for a ruff engine? (Idles just fine when engine is warm and cold) just the sound and power are different. Thanks everyone

We don't know year, model, engine, trans (there were two five speeds used in Fieros) of your car, so it's going to be hard to help you. Remember to always post all of that information as your opening sentence before you ask a tech question.

Press the pedal on the far right down till that rpm meter needle points at the 5 and then there will be less time gap between engine sparks.

At 1000 RPM there are 16/.67 revolutions per second or .06 seconds per revolution or 60 milliseconds per revolution and with three sparks per revolution that would be 20 milliseconds time gap between engine sparks.

At 2000 RPM there are 33.33 revolutions per second or .03 seconds per revolution or 30 milliseconds per revolution and with three sparks per revolution that would be 10 milliseconds time gap between engine sparks.

At 5000 RPM there are 83.33 revolutions per second or .012 seconds per revolution or 12 milliseconds per revolution and with three sparks per revolution that would be 4 milliseconds time gap between engine sparks.

If you have an SES light, the thing to do is find out what code has been generated, and go from there.

Somebody should check on the SunDrop.......

HEY I GOT MY ENGINE CODES!!!

Showing a code 23 and 32 Do you think any of those codes will attribute to my power loss?

Still wondering about the shifter as well thanks guys!

Code 23 is Manifold Air Temperature: MAT sensor (unusual high temperature reading)
Code 32 is EGR Vacuum Control

In my opinion I bet you have a crack in a vacuum hose somewhere its a common issue and I read somewhere that this guy got the same codes that you did and ended up replacing his EGR and his MAT sensor to no avail and ended up having a small hairline crack in a vacuum line, replaced the line and his engine was running as good as new (If Im remembering correctly) Just go through your vacuum lines and check them over, Hope this helps.
