Default Help!!! What do you think is wrong with my car???

About half way into a 100 mile highway drive last night I noticed some hesitation and then all I had was about 1/2 normal power. Very little ability to accelerate past 80 mph. On my return trip today, there were moments when full power was back albeit a bit rough. Siren/tea kettle noise might be a bit more pronounced too. What do you think it could be? Torn TBB, blown turbo?

Check the F hose and the TBB.

Anyone have the link that shows where the TBB is and what it looks like?

You might not have the F-hose, depending on your build date.

Also, this picture is the engine WITHOUT the bypass valves ;-)

Default Thanks guys. The one thing I don't experience is the whoosh. Just the loud siren.

I hope it's not a turbo...
