Actually, this isnít Ken, but Kenís dad- he drives during the day and torments himself working on his car at night. Well, we didnít intend for it to be torment.
Hereís our tale of woe:
Ken gets a very nice 1 owner Ď94 GT, 37K original miles, clean as a whistle, about three weeks ago. Since weíre close enough to Akron, he takes off for Summit and gets the CAI, headers, new H pipe, Flowmasters from there back, underdrive pulleys, coil, 9mm wires, plugs, & chip.
We mount everything (except the chip), fairly straightforward. Except he forgot to check the firing order before he pulled the wires... So I head upstairs and find this site, and get a firing order. Cool. But the car wonít run, or, more properly, itís only hitting on 4 cylinders. Got the cats glowing nice & red. Rechecked the site, now thereís a difference between the firing order on a ďstraightĒ 5.0 and a 5.0 HO. Now 5.0 HO is cast into his manifold, but he insists it runs even worse with that order. So here are the two of them:
1-3-7-2-6-5-4-8 (5.0L HO and 351W order).
1-5-4-2-6-3-7-8 (straight 302 - currently in place)
Iím racking my head to see if I can visualize if this is the problem. He insists it runs worse with the other order, I was out of town that night.
If not, anybody have any ideas? Whatís so special about the Ď94 that it gets the SN95 designation (as Iíve just figured out...)? If it says 5.0 HO on the manifold, why wouldnít firing order #1 work?
But one thing I noticed was that, with firing order #2 in place, we have a pattern of 2 hitting, 2 not, as this:
1 - firing
5 - dead
4 - dead
2 - firing
6 - firing
3 - dead
7 - dead
8 - firing
and that HAS to be the problem, the only ones firing now are the ones that are correct on the #1 firing order... Blast if that ainít enough to make you throw a wrench!
I think Iíll post it anyway, just to say hi, to warn others, and to give the rest of you a good laugh. Iíll try it tonight when I get home, if that ainít it, Iíll be back very frustrated!
Best to all,
