VE SS-V 6.0
Hi guys, I’ve got a 2007 SS-V 6.0. It’s got a flat spot until about 2000rpm. The car shudders and practically just feels like I’ve blocked off the intake and it’s trying to stall it’s self, just bogging down. I’ve replaced plugs, all the leads and coils seem fine, and I’ve just replaced the MAP sensor and air filter, and cleaned the MAF sensor. Has anyone had similar issues with the LS2?

Could be a number of things, 02 sensors could be founded up, exhaust leak, have you cleaned the Throttle Body recently? Vacuum leak, does it idle ok straight away or does it take a few min to idle normally?

LS2 were only in HSV's, if u can check what the 02's are doing during the event it will give u a starting point
