When driving my car a around 80-90 mph on the freeway I got on the gas pretty hard through the power band through about 5500 rpm. When I engaged the clutch to down shift, I noticed the car wasn't able to idle w/o pushing the gas pedal. I slowed down to pull the car over at which point the car seemed to sort of come back to life. The idle was really rough and sounded like it was misfiring. After checking all my gauges I continued to dive the car real slow back home. From that point forward, the car would backfire pretty bad down in the lower rpms until around 4000rmp at which point the car seems to come alive again. However, the idle is really rough, it back fires in the lower rpms under load, and doesn't seems to have the same exhaust note it had before (it's almost like there isn't the same flow through the exhaust that there was before - almost weak). Anyhow, if you have any suggestions as to where I might start to troubleshoot, I would greatly appreciate the help.
