Disadvantages of the GM LFA engine
- Since many problems here are from overheating, monitor the condition of the radiator and pump;
- Engine speed often floats due to throttle contamination or fuel pump failure;
- The reason for the tripling of this unit is usually in the cracking of one of the ignition coils;
- It is better not to save on oil, this is fraught with rapid wear of the camshaft liners;
- The thermal casing often falls off and the exhaust manifold bolts are unscrewed.
