problems after header install please help
This past weekend I installed some pacesetter long tubes and ORY. i blocked off the AIR and EGR, also i changed the plugs while i was there. Well after i finished the job im getting what seems like the car is missing out.. I have researched this forum quite a bit and think maybe it sounds like i need a tune? but im also wondering if maybe it could be a spark plug wire getting hot or possibly maybe even moved and is touching the header so maybe this is the cause of my car running rough through the rpms? please help thanks !

lswho, that was my first guess and yes those back to plugs are a pain in the butt and very close to the header, i havent had a check engine or any type of code pop up yet tho?

Spark plugs could care less what kind of headers you have, but the stock gap is .050".
OP, sounds like you don't have a boot clicked all the way on the plug or you've got a wire crossed.
You should not need programming with headers for performance reasons, only to have the EGR/AIR tuned out. A tune helps but it is far from necessary.
And without knowing the OPs vehicle year, no one can make the judgment that a code will be set.

thanks for clearing that up lol...but yeah just on a side note i'm assuming you bought Tr55's as a lot of people do..but i bought TR55's at autozone they said they were pregapped to .055 but they were really .060..i dont know if this might've been the case when you changed your plugs. but mine ran like crap when i installed them at .060

i gapped the plugs to .050 as they were not that as i was told they would be when i bought them, just went over and looked at the car none of the plug wires are lose are touching the header and i labeled every wire when i took them off so i would get them confused when putting them back on. im at a loss guys really frustrating i spend all this money and its not running right.. the car is a 95, and i used ac delco plugs that were suggested to me, which i dont think it should matter what kind of plug i put in it the car shouldnt be running poorly do to the brand of plug i wouldnt think ...

On my new build i had a dreaded P0300 code. For me the #3 plug was fouled, the baseline tune somehow didnt get the injector pulse for #3 right and the #8 plug wire wasnt on all the way. Check the connections at the opti. At work we had a 2000 Mazda come in after getting some valve cover gaskets done running rough. Turns out 4 out of 6 plug wires were crossed, no codes were thrown. If you had a wire touching the header it would throw a P030x code

The ancient Chinese secret to that is to use a #8 wire, route it along the sheath (bolted to the block below the plugs) to the back of the block, loop it back towards #5 and connect. That way the boot is pointed to the back where there is plenty of room.

I actually just routed another wire aimed backwards like you said and over the top of the primary along the valve cover. No issues since. It's been years now.

thanks for your help guys, dubga you mentioned something about the metal boots over the plug wires on the back two cylinders would u guys suggest maybe taking them off, i assumed this would possibly cause the plug wires to get melted.. ?
