Question about 5.3 liter LS4 V8
I test drove an Impala SS and Pontiac GXP and was very impressed with their performance, but not their seating comfort. I then tested a Buick LaCrosse CXS and liked its seating comfort, but not its performance (240 hp isn't enough for me). I read Buick is coming out with the new LaCrosse Super sometime this summer, and it will have the same seats as the CXS but with a significant increase in power. My question is, has anyone heard of any problems with the 5.3 V8's Active Fuel Management (aka DOD) system? I posted the same question on Impala SS and Pontiac GXP boards but haven't had any replies yet. I'd appreciate a reply. Thanks in advance.
