Ok fellas,

This is first time I've have a problem with performance characteristics with my ride. Over the last week or so, there's been a weird drop in how my car is acting. There's been a lost of power, strange engine/exhaust like noise during moderate acceleration when I get up in speed and RPMs. The shift from 3rd to 4th gear seems to take forever while noticing some sputtering giving it gas. I'm wondering if something went bad after my car shut off while idling and having the exhaust pipes blocked while I dug the car out of snow a lil over a week ago. Could it be transmission related? Car does shift into all gears normally and when starting out there is no shifting problems. I do noticed my symptoms get worse the longer it runs. My car has 186k. Plugs been changed at 120k, air filter isn't due until another 7k. Just had an oil change and cleaned my MAF and throttle body.

Any ideas?

Loose vacuum hose?

All hoses are intake and crack free. Im leaning towards TPS or MAF sensor or both.

Finally got my situation situated. $250 later the bad middle cat was replaced with an universal unit (pics below). Had it cut out and welded in. Took about an hour at the same exhaust shop that did my other exhaust work. I took the liberty of painting the pipes black but ran out of paint so i'll finish later. It just looks better blacked out to me. My power has returned with a vengeance. The substrate inside the faulty part had broken loose and created blockage with rattling. Although im happy it's done, i wished i couldve found this out first. By throwing parts at it I replaced both front cats, a coolant sensor, a B2S1 oxygen sensor, and a MAF sensor but given my mileage and age these parts were about due to be swapped out anyways so no big deal. With all those new parts on it i can really tell the difference and mpg's instantly went up. Glad this is now over so i can get back to putting the engine mounts and revitalizing my suspension in which the ball joints, tie-rods, rack bushings are still due. Also a new set of oem 18's will land before the summer hits.

Catalytic Converters have caused some strange things over the years. I remember Dearborn Michigan products of the 80's wherein the platinum coated beads of the Cat would rattle loose and migrate to the muffler/resonator that was located immediately ahead of the right rear bumper - where the beads did what they are supposed to do, GET HOT, and the mufflers would exhibit a noticeable red glow (and caused an alarming amount of fires) that could be seen at night by the driver following the affected car.
