Changed plugs, WTF HAPPENED!!!? (long)
I swear everytime I put an aftermarket part on the car has problems(clutch and fly). Ok as of lately my car seems to be hitting either fuel cut or missing in 3rd gear around 6.5k rpm around 10-11 psi. No biggy, I'll change the plugs right, WRONG! I change the plugs, I origianally had 7Q's and 9Q's. I bought 7QP's and 9QP's. I changed just the plugs and not the wires. I haven't changed the wires since the life of the car. About 3 years and 20k miles.
Prior to this I took off my air pump, it wasn't needed anymore with a gutted main cat. After that I was getting like 12 vaccum where before I was getting 15,16, and 17 vaccum. I was like well I guess that's expected with the rough idle also since I took off the air pump and that seems to be normal to have a little rougher idle.
Well I get home and start taking the elbow and what not off to get to the plugs. Change them no biggy. Put everything back together after double checking to make sure the boots were on the plugs good. I start it up and immedietly I get a bunch of smoke out, more than my usual norm because I premix and still use the OMP. Smoke is still heavy and doesn't want to seem to go away. I smell it for a little bit and after singing my nose hairs trying to smell what kind of smoke it is since it's night outside already and I have a little light with me. It doesn't smell sweet what so ever. Smells pungent like really rich. It was shooting flames if I revved it to 4k rpm and it would do a loud pop and a flame sometimes lower. The car wouldn't smooth out till around 3.5k-4k.
Car is idleing like I'am Abel Ibara with a monster street port or bridge port, just BRAP BRAP BRAP. I had a little port sounding before since taking the air pump off made it a little loopy but now it's really loopy, I have stock ports. I left it at that right now because it's night and you can't really work in the night. I'am seriously pissed right now and I don't know WTF to do. Any help guys?
** I don't have the silicone hose job done because I never needed it, vaccum WAS good.
Seems like tomorow I will get some plug wires and change them also.

Yup everything was in right.
IT WAS MY MAP SENSOR!!! Damn it, I let out a huge sigh of relief when I double checked it and found the hose wasn't connected. Sorry mods you can go ahead and delete this thread. I'am so relieved.

From the factory, 7s go in the lower (leading) holes and 9's go in the top (trailing) holes. Many people with a few mods run 9's all around.

I don't keep plugs IN my car longer than about 2000 miles maximum so I used to run the regular non platinum ones. I now run heat range 10 Iridium plugs and those are better for my car (single turbo running it hard).

I did the exact same thing when I changed my plugs a while back but I wouldnt recommend EVER starting the car without that hose on because it will flood, quickly and very badly!!! Took me awhile to get her unflooded when that happened. Have you tried starting it up since you put the hose back on??

No. I took a breather then came back out and found out it was my hose on my MAP sensor knocked off. Put it back on and it started right up. Went for a drive to clear all the carbon out. w00t w00t!! I got platinums!

I can now do all four in about 15 mins. My first time took me closer to 15 hours. I just go from the top by feel. I've never taken off the intake elbow, but it supposedly makes it easier.
This is important: Make sure you do one plug at a time, and do NOT mix up plug wires. The leadings fire off the same coil, so no biggie there, but be very careful of mixing up trailings or a leading and a trailing.
Oh, and be very gentle threading in the new plugs.....hand tighten them, then give a half turn with the ratchet. Aluminum is soft and cross-threads easily .

this is off topic...
im done putting my turbo back and all the necessary parts (LIM, UIM & etc..) i changed a lot of stuff while i was in there... dumb for me, i forgot where the spark plug cable go!! hahaha... i know which is the leading and trailing, but where does the T1 and L1 go?? which is the first rotor??
