S/C Falling on its face???

ok...so...ive had this issue recently with my car on the highway. I will be cruising 80 or so in 5th, give it a little gas...and it boggs...it boggs hard! Then it will bog in every gear untill i shut the car off and turn it back on. It has only done this a couple of times, and my mods are in the sig...any suggestions?

It maybe a throttle position sensor...or hopefully just the plugs? Other than that...I'm sure you've got a good tune and have been running it for quite some time...the cat should be good...hmm....

dude you gotta put the badges back on!

Does it only start doing that if you hit it in fifth? Or do other gears do this as well?

i doubt its the throttle position sensor- if that goes out, the car goes straight to limp mode.

If it's the cat- he'd be boosting well above normal limits.

i still doubt the throttlebody, even a dirty one is unlikely to cause these symptoms.

vacuum leak is possible though.
