ok, can someone give me a diogram of what each wire from the dirst to plug is plugged in.
all I know is that the firing order is 123456, thats all, I think I have one plug hocked up to the wrong plug.
my enigne has little power.

Also,
will me getting a new egr calve fix my hourspower need???

#1 is the rear passenger side most, #2 front pass side, #3 rear middle, #4 front middle, #5 rear drivers side, #6 front drivers side
The easiest way to determine which pole on the distributor is #1 is to turn the harmonic balancer until the big mark is on 0, then see which pole the rotor is pointing twards. Wire it. If it does not run, then switch all the wires with the opposite side IE #1 to #4 #2 to #5 and #3 to #6 on the distributor, this will rotate the firing order 180*
The EGR valve will have no effect on peak power output unless it is stuck open. The ECM turns off EGR pretty much anytime that you are not cruising at a steady speed, and always when at WOT.

----5-----1-----------------------------
--4---------2---------------------------
-------3----------------5----3------1--

I think my fireing order is switched too after degreasing my engine today. It's dark out so I will have to wait till mornin' to see if maybe that's it cuz damn it feels like I'm hauling a train cuz I have considerable power loss but you wouldn't notice by sound. But i noticed the engine sounded just a tad off before degreasing. Dist. is completely dry inside and out.

Question, does it matter what size mm wire you use on a plug?

86SE, that doesn't look right. I'm referring to the manual. Doesn't match up. So damn confusing this is.

rotate the distro side by 2 clicks clock wise and it is more like the manual.

that's weird it cut off half the quote

Found very good pics:

Rotor: http://web2.airmail.net/jsavage1/formula/rotor.jpg

Firing Order: http://web2.airmail.net/jsavage1/formula/rearwires.jpg
http://web2.airmail.net/jsavage1/formula/frontwires.jpg

Nvmd, they look exactly like it in the manual. Hopefully all goes well.

In the pic below::: If you look at the tops of the wires on the distributor cap, the furthest one away --next to the coil wire--with the black casing on it--is your # 1-----its is also closest to the small black vacum nipple leading into the plentum--then just head towards the rear of the car---or clockwise 2 3 4 5 6 .

http://web2.airmail.net/jsavage1/formula/rearwires.jpg

If your standing behind the car looking at the trunkside--to your furthest right is # 1--then the middle is # 3 ---then the last one on drivers side is # 5.

If your standing behind the car looking at the engine--(This is the front wall) the furthest plug to the right is # 2 then the middle is # 4 then the furthest one to the left is # 6

The diagram in the manual is wrong--so your not loosing your mind!!!!

avengador1--all due respect--all 3 of my 2.8`s are running with # 1 being one post back past the distributor cap hold down screw ( in short) the post that is 1 back going counter clock wise.. When I saw this diagram the first time it was posted --I switched over all 3 of them, and they did not run correclty.

my 2.8l is set just like in the book and is running just fine.

Is it possible that TDC has been set differently on some fiero's? Look's like we all agree on the position of the plugs on the engine. Looks like the question is where is the number 1 plug wire is suppose to be on the distributor.

Whether your distributor is one post off is irrelevant as long as you have the crank timing mark at TDC(top-dead-center) on the compresssion stroke and the rotor is roughly 5-10 degrees counterclockwise from whichever post you deem(ed) to be #1. The hard part is ensuring that the correct timing mark is used(I believe there are 3 grooves cut into the harmonic balancer) and it's on tdc on the COMPRESSION stroke. The mark you want is the big fat groove. Once you locate this groove, paint around the groove(not in it with white or very light paint and also mark directly 180 degrees opposite from it with the same paint on the front side of the pulley so that when you are on the ground rotating the engine with a wrench, you'll know roughly when TDC is reached. As for the compression stroke, the easist way to determine that is to remove spark plug # 1 and the wire from the coil(so the engine doesn't start). Then put your finger by(not in) the plug hole and have a helper bump the engine with the starter in 1/2second bumps. When you feel the air rush past your finger, you'll know that you are at TDC or just barely past it. Use the wrench on the crank to fine tune you timing mark and then, your number one distributor post should be slightly clockwise from the current position of the rotor. Then all of the other wires would be hooked up in clockwise order( #'s 2-6) thereafter. Once this is accomplished, the engine should be able to start (after you reconnect the coil wire) and you can use a timing light to fine tune the timing.
