Are there any pics for the removal and installation of spark plugs? I am 6'2 and I cannot get to the rear three. Please advise and thanks

I come in from the side (both sides). Remove the battery and the plastic shield on passenger side. Some people also take off the decklid. I have never had to do that.

I stand in the trunk and place a towel on top of the motor so you dont end up with bruses. You might try removeing the battery.

- Remove decklid (I can remove by myself even with a spoiler on it). You do not have to remove it but I like the extra room and it's easy to do (takes five minutes)
- Mark and remove plug wires
- Spray some penetrant in there on the plugs
- Lay something to cover engine
- Let sit for an afternoon
- Remove plugs

Never have had serious issues with rear plug removal - and I've worked on a WHOLE LOT of V6 Fieros. It's not hard to do I promise. Also if you have access to compressed air I'd use it to blow crud out from around spark plugs.

Just don't force the removal of the plugs. Too much torque can break the plug and will make the work even more difficult. When I did mine on my 88GT (after 50,000 miles) it took me three weeks for the penetrating oil to free up the plugs for their removal.

Guys..you may think I'm nuts...BUT...I use a leaf blower to dry my cars and made a make shift "nozzle" with a narrow tube to blow into tight small spaces like spark plug areas..Try it !!!

Yeah, that would work. They also sell canned air. A small compressor runs less than $50 on sale.

Just did mine - pen oil for a week - cleaned out with air - hood off to get to rear plugs - mini fridge within 15 ft. Package of bandaids handy. One came out easy, four were a battle and the final plug- middle near the firewall snapped off I'll hit it with freon and an ez out tomorrow and hope for the best.

I'm 6'1" and I managed to do mine by squatting in the trunk. I used a socket with a swivel adapter and just felt my way around to get the socket on the plugs. It took about an hour to get them done, but would probably have taken the same or more if I had to re&re the deck lid.

Wish I had thought of using a towel in the trunk, or not worn shorts, could have saved myself some pretty badly skinned knees....

What's the deal with the rear plugs? Those are the easy ones!

It's the three spark plugs towards the front of the Fiero that are a bit more of a challenge.

Now that we've clarified that... I take the decklid off my '86 GT as well. It has the "recall" weatherstripping on it which I find gets in my way to do the front plugs. Four bolts... and it's off. I just stand in the trunk, lift, and place the decklid on the roof (which is covered by a large flattened cardboard box). Makes the rest of the job much easier.

Thanks to everyone!

I'm 6'4", and I can do the back plugs by leaning over from the trunk. After a couple of times you can "feel" where the plugs are.

I also suggest removing the deck lid. It makes the job MUCH easier, and it's very easy to line up when you put it back on.
If you leave the engine vents out, you can put the bolts in the decklid finger tight, close the lid and nudge it into place - then tighten the bolts down while it's closed through the vent openings.

Use Caution when removing the deck lid, you could bust out the rear window if not done right.

Probably easier to disconnect the dogbone and rock the engine back for a little more space.

Got Lucky !!!! also took the time to service the K&N filter cause you have to have the hood off to get it out!

So many people make a big deal out of replacing the front three plugs on the Fiero V6. Today I replaced the plugs and wires on my daily driver Pontiac G6 with the 3500. Changing the plugs on the Fiero V6 is a walk in the park with a great big ole ice cream cone compared to replacing the plugs on the G6. It is similar to the Fiero in that the 3500 is a 60 degree V6 with the same spark plug orientation as the Fiero, but the access to the back side of the engine requires Houdini like positioning of your arms. After doing that today I would gladly change the plugs on a V6 Fiero any time.
