please help Something's wrong with my car.Mods are in sig.The car will turn on but the it shuts off at cold start,and gotta keep trying till it finds idle.Once its warm it won't do it again.The computer read misfire in multiple cylinders.We changed spark plugs,wires,check for compression etc.i feel the car is slower.When going part throtle the car takes of fine then it slows down and then back on time.I downshift and it shifts good.Lights flicker on the dashboard and also the blinkers.Coul this be a short?I don't think is the cam since its so small(221/221 .558 .588 112 lsa),plus i got ls1_edit and car worked wonderful for about 3 months.i noticed a decrease in performance,and somehow it doesn't sound as loud.Took it to several people but they didn't find anything.Any help would be appreaciate it.

The Dash lights flickering could definetely be a short, which could cause all sorts of funky problems, but I don't see how sound would be one of them. Maybe the timeing on the car is off a little? I don't know man.... 
I'm having low power problems w/ my Z, and nobody can figure it out either. :sad: Good luck to you, if you find anything, let us (especially me 
) know. If I get to the bottom of mine, I'll let you know. We may have the same problem.

I won't lie. I had to get on Yahoo Maps to find that place. Was just curious if you were anywhere close to see if we could get together and try and troubleshoot...but you're like a 9 hour drive 
sorry bro.

CHeck all your sensors, especially cam and crank, check inside the MAF wires, check harness, something maybe melted or pinched.
Once you are 100% sure it is nothing electrical, then think mechanical.
Did you try to contact AMS/TSP/MTI those guys have done more f-cars than you have hair on your head.

make sure the maf is properly hooked up and is clean, dust particles or dirt on it will cause it to read wrong, which will cause your car to run messed up or lean
