Fellas,
It is time for me to do a much needed tune-up. The Fiero runs fine. However, since it is being driven to my job 1,300 miles away and has to be smogged, is there any particular items I should replace or pay attention too?
What are the BEST spark plugs to buy? I already changed the oil. OK guys, any ideas?
Cordially,
kevin

Change:

O2 sensor
use stock AC delco plugs
wires
cap
rotor
fuel filter

Check for exhaust leaks, EGR function (valve and solenoid), vacuum leaks, timing

At least to start. Not sure what you have done already.

I second checking timing, I always use Autolite plugs, have had great luck with my 3800sc with them. Copper is fine. I know some say it doesn't help but, you should sea foam it, I seafoamed every car we've had and it made a noticeable difference in idle quality and response on all of them. You just buy a can of Seafoam from a parts store, you pour 3/4 in your tank, then the last 1/4 threw the vacuum system while its running. The goal is to pour fast enough that the engine stalls. Let it sit for 20 mins, then go for a hard drive. And enjoy the show! Before you seafoam change the plugs/fuel filter. Basically do it last.

Fellas,
what do you think of the new spark plugs. I forget their name, one type is called Aridium? Or, the other is E3?
Let me know

Really.... OEM AC Delco are the best plugs for the Fiero (in stock form).

Standard NGK's for me...Only plugs I use.
Make sure you have quality plug wires and that they are in good shape.
Clean inside of throttle body regularly with carb spray.
Don't overlook coil & ICM plug harness condition.
Sea foam.....

HEI can use "normal" AC etc Plugs or basic Platinum types from AC etc.
I use basic Platinum because is cheap and some use better metal or coating on metal that resist rusting. V6 and L4 does rust the plugs allot depending on when you live/drive and car is park.

Don't bother with "gimmick" "special" etc plugs. Many cost money and do little or nothing, or worse cause problems.

If car runs good then save old parts for spares. New parts can have problems out of box or soon and good spares are very handy.

+1 on NGK's. They are what I use in all of my cars. I like the G-Power platinums......I haven't had any issues over the past 10 or so years I've been using them.


Everyone has their preference on plugs and engine oil and brand of gas, etc., etc. It all comes down to personal preference....use what you like and find a brand that agrees with your car.


That said, I will say that I would avoid Bosch O2 sensors.....I've never had good luck with them. I've been using NTK and Denso O2 sensors on my '88 Fieros for awhile now with good results. They look like the OEM ones too (not that it really matters much).
