I was driving home last night, (babying the 300) with the odd squirt here and there... Then I noticed half way home a loss of power \ hesitation when taking off from the lights. Got home, turned her off... Started her again 5 mins later, same thing. Definitely feeling hesitation, as though she doesn't want to change down a gear... more like wanting to hold a higher gear. So I put her in neutral, and gently rev up from idle to 2k... approaching 1.5k the engine was hesitating, and at 2k started vibrating... so I quickly let off the gas. Can anyone please explain to me what happened, and how to resolve it? My car has been good to me so far, and I look after her. :zlove:
Hello, I know this is my first post. But first port of call would be checking the ECU for any codes, it might help you narrow down what the cause of the problem is, quite easy to do, remove the carpet from the kick panel in the passenger foot well, remove the 4 x 10mm bolts holding the board and remove, on the side of the ECU will be a little screw, with the ignition in the accessory position (car not started) turn the screw with a flat head screw driver fully clockwise, wait 2 seconds and then turn the screw fully counter clockwise back to its starting position. then on the dash you will have the engine warning light flashing, count the flashes it gives, long flashes are the first number, short flashes are the second number IE: if it flashes 2 long and 3 short then repeats that, the error code is 23 It can flash up more than one code, so you need to pay attention. if the code is 5 long flashes, followed by 5 short, then its code 55 and no error codes are present. To get out of ECU code checking, turn the screw again fully clock wise, and then fully counter clock wise. But working with the information given, it could be the MAF. Codes for the ECU check are as follows. 11: CAS circuit 12: MAF circuit 13: engine coolant temp. sensor circuit 14: vehicle speed sensor circuit 21: ignition signal circuit 26: boost pressure sensor 31: ECU 32: EGR function 33: exhaust gas sensor circuit left 34: det sensor circuit 35: exhaust gas temp. sensor circuit 42: fuel temp. sensor circuit 43: TPS circuit 45: injector leak 51: injector circuit 53: exhaust gas sensor circuit right 54: signal circuit from A/T control to ECU 55: No Errors shown

...and now all is back to normal... without touching her... random... :rofl: So I will continue to treat her with love and respect :zlove:
