hey, new problems- took my car out for a test run, and under load, it stumbles/hesitates, and sounds like it pops out of the exhaust. the 30 mile drive I took it on didn't help at all, so.........any ideas. No vac leaks to speak of, I thought maybe boost leak, but I didn't see anything noticable, I also thought maybe coolant temp sensor. But what do you guys think?
Also, the idle is kinda erratic, it fluctuates between 400-800 rpms. The consensus indicated a boost leak but could it be anything else
