car is missing after Lt install(help)
finished Pacesetter LT, ORY, MSD 8.5mm wires NGKTR55 plugs.
When the car is under load and inbetween 4k and 6k it will miss fire.
Any idea?
So i checked all plug wires .......All on good
All plugs were gapped at .060
Thought maybe crappy plugs so i bought AC Delco platniums gapped at .060
Still craps out in the top end...ANY IDEA??
I think my ORY is hitting so could it be the knock sensor retarding the engine?
Has this ever happened to anyone else?

Do you put the headers in with the sparkplugs in? If so, you may have cracked one of the plugs accidently with the header. Check all your plugs in addition to check your wires. I know you said you checked them, just make sure that they are on "double clicked". The NGKs are one of the best plugs. I don't think it'd be the plugs.

i know its a long shot, being that its still a bolt-on car, but maybe its a tuning issue. u may be running a tad lean/rich at the top end. other than that, i would pull all your plug wires off and reattach them, making sure u hear the double "click" to assure they are on good. its very easy for one of the rear cylinder plug wires to be half-way on, being that they are kinda hard to reach. once u have exhausted that option, id say you may have fouled an o2 sensor after installing the ory pipe.

my car did something really similar to this. I check everthing. It turned out that one of my new msd wires was twice the resistance of a stock wire. After i got another new wire it ran great.
