Hi Guys, I'm sure you may have already covered this, but I need your help. I have a 2003 Ba Xr6 Turbo (auto) that has done 110 000Km's, only things changed on it are CAI, Dual 2.5 inch cat back exhaust, and plazmaman STG1 piping kit. The car makes 253rwkw's. The Cars been running fine until just recently. The problem is that you can drive the car normally all day, and no problems, but give it a boot and as it starts to take off, it feels like it losses all power, starts shuddering gives no accelerator response at all, but give it a second, tap the accelerator a few times and she comes good again. Now I know the first thing most people will say is, change the coils. Been there done that, several times, replaced plugs several times as well. Sinclair Ford said that they can't find a problem, my local mechanic gave up, so I took it to Springwood Car Care today. The Car spent half the day on the dyno only to be told that it was the plugs, so he changed them and said it was fine. I drove it home and the same old problem is still there. Now I'll ring the mechanic in the morning but any help from you guys out there would be good, as this thing is pissing me off and hurting my pocket at the same time. Thanks Guys P.S. This is my first post, so please be gentle.
