I just picked this Fiero up today after not owning one of the little guys for a few years now. I was driving it home and it just seemed like the rpms were too high for the speed I was traveling at. I was going about 45-50mph with rpms around 2500-3000.

I DO plan on doing a full tune up this coming week so hopefully that'll take care of some issues like that

Must be an automatic. Mine does 3000 at about 67mph. 55 mph is near 2500 (providing that the TCC is working properly). Stick shift ones do a little better

ditto, on my 3 speed tranny.

That does seem a bit high. Assuming it has an automatic transmission, I'd check to see if the torque converter is locking.

i did notice that it didn't downshift sometimes. i had to manually put it into 2nd (yes, its an automatic, sorry i didn't mention that) and once it got up to speed, i'd put it back in drive and it was ok

55MPH is 1500 rpm on my 86 2.5 with a 5 spd. 37 mpg right now, hopeing for better as the new rings seat in.

Check the adjustment on the TV cable that runs from the throttle body to the top of the trans. If it's not adjusted right the trans will not up shift or down shift properly.
