Tu kia engine replace krne se ECU ka problem solve ho jaye ga I am also facing such issue with my Suzuki Cultus 2007 Efi. I bought it recently and soon after purchase I felt that car is missing. Its race gone up and down automatically. When I got it checked I was told that it looks that sometime back its wiring was burnt and its ECU was replaced with Suzuki Alto 660cc Japanese which does not support it properly. So please any one expert on this issue guide me to resolve the issue. I will be grateful. Younas Ican be contacted on 0324-8543474
