Installed bolt-ons on my car last (5/16 plenum spacer, JWT Popcharger on a Z1 intake tube, Z1 test pipes, Invidia Gemini catback exhaust, and a Zex wet kit).

When I started the car it was skipping pretty roughly and giving the blinking service engine soon light.

I tested all 6 coils and it made no difference,they all seemed well. Tripled checked to make sure all lines were connected.

What do you guys think the problem could be?

 

throttle body connection and maf connection.

 

I checked the MAF and it was fine too, and I'm pretty sure a friend checked the throttle body connection.

 

somethings unplugged just check everything you took apart.

 

dissconnect no2 and see if it runs any better.

 

By no2 do you mean the nitrous?

I unhooked it and it didn't make a difference either.

 

If all that went on at the same time, a simple tune from a Nissan Dealership should help too. Had a similiar issue when I changed to the Kinetix Plenum and PopCharger. It drove fine, but idle was REALLY rough and sputtered. A re-tune to re-map the MAF took all of about 15min and he drives like a champ now.

 

I thought about this also, but my car idles AND drives rough...

 

Air leak somewhere. MAF sensor backwards?

 

Reinstall the plenum. You sound like you have an air leak somewhere.

 

I got the car to stop misfiring and was going to close the hood and when I did, the hood hit the popcharger and pushed it down. when it did, the red MAF wire split open and it touched a bolt or something and grounded out. Now the car won't start and the TCS and Slip light are on. The car will turn over but isn't firing. I checked all the fuses in both panels and a friend tried to scan it with a scanner from 2005, but the car is a 2006 model, and it wouldn't read anything at all. My guess is that the computer is toast, although I don't know how that one wire grounding out could cause that to happen. If I'm wrong, please let me know. I need all the help I can get!

 

flatbed to the dealer sounds like the best option considering the problems due to basic bolt-ons.

good luck!
