Changed Coil, Distributor cap and rotor button, Spark plug wires and spark plugs on my
Fiero today and boy that was a job! They ain't a whole lot of room to work with in that engine bay. Did some painting in spots. I've officially sprayed my scent on that girl. She's mine. I've had her a year and 8 months and this is my way of making her officially mine. The previous owner was good to her but I'm better to her.

Welcome and yeah, not a lot of room to change those forward plugs is there?

It's worse than some cars, better than some cars, my 2001 Sebring, the rear plugs are under the cowl (wipers etc), and coil on plug, so I need a deep socket and extension, I have to feed each part in individually, drop the socket on the plug, drop the extension onto the socket, drop the ratchet onto the extension, then once loosened, I have to somehow figure out how to disconnect the extension from the socket (can't pull it out far enough to even touch the socket before it hits the cowl). That was a long job haha.

Removing the deckled to change the front plugs is pretty simple.
It makes access much easier and you need fewer bandages after finishing changing the plugs.

That is certainly an option but deck lid realignment can at times be tricky. I've had to use two people to align the deck and not scratch anything. With the tool you just take off the dogbone and replace it with the engine tilter. You just tighten the tilter with a wrench and it opens up plenty back of room back there to easily change the spark plugs. One man operation. That's how the pros do it.

I don't know if the tilter is the best idea, the engine isn't designed for it, the muffler is mounted to the cradle and there are no flex pipes anywhere in between, and the engine/trans mounts should resist that movement a lot, or potentially tear, with my old mounts (2/3 decent shape), I had to use a prybar to pull the engine backwards enough to just get the dogbone in, they are already supposed to have significant tension, to keep the engine from rocking a lot back and forth in the neutral zone between all bushings/mounts preload. With my new mounts, it took quite some time to get the engine far enough back, and was a chore. This tool is meant more for vehicles like a 1993 Pontiac Grand Prix, where the mounts and exhaust and everything were designed for that (and it is in the manual to do that), flex couplings, much less triangulated engine/trans mounts (but 2 dogbones to make up for it), etc. the rear plugs on that are impossible to access without tilting the engine. The Fiero isn't that bad. If the dogbone puller works or is even used, I'd be suspicious that your engine/trans mounts are either very old, oil soaked, and soft, or something has already fully separated, the exhaust won't like it either. GM designed many vehicles to take advantage of that tool, and those are the vehicles the pros use it on, the Fiero isn't designed to use that, and I don't see how it wouldn't cause damage.

having done the plugs on a 95 grand prix gtp woth a lq1 i can say you dont need the tool. it just sucks and takes an hour. as for fieros the worst time ive had changing plugs was on my gt when half the metal hex broke off. also you can use the puller for replacing the front trans mount a little easier
