Holden barina multiple misfire

The codes are as follows : P0120 = Throttle position sensor (TPS) circuit 1 voltage high/low C-09 and Throttle position sensor 1-2 Correlation C-09. P0220: same as previous code. P1550: Electronic throttle control reduced power C-09/Electronic throttle control forced idle/" " " " power management C-09/ " " " " throttle control engine stop C-09. The first symptom of this is a misfire often followed by a check engine light on. The fault code to go with this is P0300 random misfire detected. Due to the common fault for coil pack issues, many mechanics assume this code is the result of a faulty coil pack and put a coil pack on it, only to find the fault is still there. May 21, 2013 · p0300 random misfire without a specific cyl eg: p0302 etc says that all cyl are out of time common for these to jump a tooth on the timing belt (TK Barina) when they are cold the extra fuel compensates for the retarded timing when its warm its just too far out of range which explains why the disconnecting the egr and O2 sensor improves it..
