OK so i just got my car back last friday and am now having trouble with car as tho i dont have it tuned. I had the car tuned at TSP last friday and has been running great since today. It acts like its missing, or something, i dont know im just really pissed, when i get about half throttle it starts to studer and act like its not getting gas does anyone know what this could be. I have to sit at stop lights and leave the rpms around 1000 to keep it alive but as soon as i let off of the gas it will stay running for maybe 10 secs then dye. Also when i start from a roll from the intersection it trys to dye kinda like its not getting any gas, and i know there is gas in it. I dont know im just pissed.

thanx for all help

Well i havent had a chance to call jason just yet but i did go threw and look around at some things on the motor, like i checked all spark plugs to see if any were foud, i did notice they looked alittle brown so that leads me to belive i was running rich, another thing i did was check all hoses, and took of fuel filter to see if it might be clogged or something. Ok so after all that i went ahead and called a friend who has a OBDII and hooked it up, 2 codes came up P0131 and P0171 which is bank one is lean and bank two is lean? I dont know what to do, so i just thought i might see if anyone else could help me out before i have to spend money on this damn thing again!

thanx for help

i had the same thing happen in my daily driver and my father's truck, turns out it needed a new coil and some wires.

It has brand new msd wires, why would the coils just all the sudden give out?

Y2kforgedSS

Lets say the coils are going out wouldnt that mean i would run rich, cause the OBDII told me i was running lean on both banks.

Well, shortly after installing brand new Taylor wires
I ran into a sudden loss of power on the highway and
a SES light. Hooked up the HPTuners, found one cylinder
full of misfires, turns out one of the wires had worked
itself loose (one little plug-end clip was not tight enough
to stay put).

Just because it's new, doesn't mean it's right. You could try
pulling and reseating the plug and coil ends of each wire
in turn, feel for the "click". That's a freebie....

I did that but still no good, I dont know what to do the car barly runs at all and just sounds like 7 cylinders are gone.
