My S3 XR8 has developed a flat spot, and i mean flat spot when cold. so after letting car idle for a couple minutes each morning so melt the ice on the windows, i drive off and there is no power until revs hit 2000, i mean nothing, the more boot your give it the more it gurgles and slowly creeps to 2grand, then its off like a two stroke coming on pipe. 2-3kms down the road its fine. although it doesn't seem to have the same response from idle that it did a year ago. it does it summer and winter. Ford had the car all day Friday and can't fault it. I replaced the
MAF sensor (another second hand one) at Xmas time and it behaved itself for a couple of weeks then back to the same.
Any ideas? TPS, temp sensor, squeeky cam sync, blocked jets, coils, leads, O2 sensors??
Any suggestions would be greatly appreciated, this is pis... me off.
Can stock bar HMS intake, K&N and full HMS SS zorst.
