I found spark plug replacement on the V-6 Fiero very easy using my method discovered while working @ Jay Pontiac of Bedford Ohio. From the interior remove the screws fastening the firewall console box and set it aside. Unclip and push the main engine harness through the firewall (no need to separate the connection) You are now looking at the 3 spark plugs through a 4.5 X 4.5 inch hole in the firewall.
@@chrisloveall2821 Good Luck. Hope it helps. I remember way back from the 80's, my boss called me out and said there was no way I replaced those spark plugs in a matter of minutes. Customers would bring them to the shop for the fire wall side only plug replacement. I'm not sure which rear center console style you have but removing it and going through the fire wall is a game changer. Even today it's a very little known shortcut in the V-6 Fiero community.
On your spark plug gauge are two small tools that allow you to bend your Gap and change it without using a pair of pliers which might break your porcelain it is a tool for gapping and gauges for measuring
My brother is a mechanic. Many years ago he bought me a Snap-On 3/8 drive ratchet that had a bend in the 8 inch handle and a pivot knuckle at the head for use on my Fiero. There are similar ones out there, but their handles are bent away from the socket side, mine was bent toward the sockets and it was perfect to get at the 3 firewall spark plugs on my Fieros. He may have bought the the one with the bend "away" handle and flipped it for me. I have had my current 87 Fiero GT off the road for 6 years. I am getting it going again, so I am spraying Fogging Oil in the cylinders before I crank it over. Of course, I misplaced my special Fiero Spark Plug Ratchet. I found a really nifty one at Harbour Frieght for only about $19 USD. This one has a knuckle at the ratchet head, and another mid shaft! You can use it straight, or click it in S shapes. It works great on the Fiero. I couldn't post a link, but you can find it online.
After acquiring my 87 fiero way back in the early 90s.... I had the foresight to apply a small amount of anti-seize on the threads of all the plugs.... now many years later a change of plugs is worry free.....
Thanks, Andy. Just purchased an '88 GT. Shipped it from Ohio to Tennessee. 84,000 miles. Salesman said it ran fine. Wouldn't you know, it doesn't! Accelerating is OK, but sustained and coasting speeds, constant interruption in running. It's not a jerk but it is audible and mildly felt through the chassis. I'll check everything. First with the plugs. I'll stay tuned to your other videos. ☺
That I’m not sure of I know the rubber in the socket will lock onto the metal of the top of the plug but it wont grab the nut on the spark plug so maybe just a deeper socket?
Check the fluids, oil primarily. Make sure the engine turns over. Also listen for the fuel pump to prime. If it wasn’t stored properly the fuel system could be seized up
Man I have a 1986 Fiero SE V6 and I am terrified of doing this by myself. I have the tools and spark plugs, I just don't want to break anything or fuck anything up....
@@PhillipsVision fair enough. I have never done it before so I am a little nervous but hopefully they dont snap and get stuck in there. Wish me luck! 🤟

Awesome input, thanks 👍
Whaat ? ..I have to look at that, really need to replace the plugs in my GT..

Thank you... I was cringing the whole time, nearly wrote a "TH-cam Comment" (rudely spoken) before I saw your more constructive comment here, lol

Gary McAleer also check the cables. They can also cause misfires
@@PhillipsVision Thanks for getting back. I always appreciate expertise in every field of study and trade.
My socket won’t even fit on the rear spark plugs and they’re still whole, any tips?
Wilson’s Adventures is it not long enough?
That I’m not sure of I know the rubber in the socket will lock onto the metal of the top of the plug but it wont grab the nut on the spark plug so maybe just a deeper socket?
Wilson’s Adventures you can buy a longer socket
I tried a deeper 5/8 socket and it still won’t grab
Wilson’s Adventures you may want to get a camera behind there to see what’s going on
Imma be getting a 1987 fiero mon it’s been sitting for 10 or so years what is the first thing I gotta do

RELEVANT it’s actually very easy. The ones along the Firewall are a hastle because you have to reach around and feel your way with those
@@PhillipsVision fair enough. I have never done it before so I am a little nervous but hopefully they dont snap and get stuck in there. Wish me luck! 🤟
RELEVANT just be patient and make sure you have a solid and straight connection with the socket
@@PhillipsVision I managed to get the first 3 replaced, however, the 3 along the firewall are nearly impossible to get at. I am not sure what to do.
Devin Markovich you’ll have to reach around and feel your way. Use a small 3” extension and a small ratchet. It is a pain but is doable
