i have a 2007 shelbt gt 500 convertible and took family out to dinner tonight and the engine light came on took it to auto zone and got these codes. just filled her up today before dinner, have had the car for a year now with no problems. any ideas, this car is not stock by any means has custom exhaust one piece drive shaft, super charger kicken almost 750 on dyno, with 2900 miles. any ideas should i unhook battery and see if it comes back. code p0430, and p0153

 

Both are usually related to a bad o2 sensor... If you have cats too.. It could mean an exhaust leak before cat or between o2 sensors

 

Make sure ur cai is buttoned up toght
