All this talk about ground wires got me out peering around my engine compartment. What I found was the factory ground that runs from the block to the battery tray was broken and the battery tray was all but gone. Did someone say that Fieros don't rust? Luckily, they'll still available from the dealer... $50 Canadian. Anyway, I replaced the ground cable and added two more (one from EGR bolt to the battery tray and one from the transmission to the car's frame). The idle is certainly more stable but I really hope that the gas mileage improves! Something in the neighbourhood of 45-50mpg would be nice.

JK, I gave you a plus for the great idea!

Do also check your exhaust ground as it is essential for proper oxygen sensor operation.

Where's the exhaust grounded?

I think its grounded through the exhaust manifold bolts. As rust develops its questionable how good the ground actually is after all these years. Measure the resistance to be sure between the outer shell of the oxygen sensor and ground on engine and chassis.

I checked the resistance from battory to engine block with a meter. It showed perfect.

I did find one of my gounds was bad. I took off the one that goes from the NEG batt term, to below the battory.

It was all rusted and dirty. I cleaned it and bolted it onto the EGR controler.

I seem to be getting a better idel. My meter shows the same reading though.

The thing was really crusty and something everyone with a fiero should for sure clean/inspect.

its been a few months and there are alot of noobies here , i just thought i'd bump it back up to the top for a while again
i have also added another Pc. of 4Ga. from the same spot under the EGR Solinoid directly to the negative terminal on the Battery,

just a bump for the noobies or anyone else who midded it in the past
