So after a thorough warmup I start driving down the highway in moderate traffic, as I'm driving I notice that under acceleration I hear little burps. As I'm nearing home I give it some gas maybe a little more than half throttle and she starts stumbling bad...basically wanted to stall out and die but I give little bursts of throttle to limp home. At the light I had to keep it in neutral because it would have stalled in drive. The scanmaster showed no knock but the 02 was flashing between 170-270. When I got home I put it in park and 02 went to 678 and then it was about to stall again so I cut it off. This experience reminded me when I blew a coupler on my other turbo car but I checked and didn't see any busted couplers or blown hoses. Is there anything else I should be checking? What am I missing? Thanks
