The car 01 1.8t Jetta.
This usually only happens while driving on the hwy. I'll be cruising along, then it feels like I'll have little to no throttle response for about 5 seconds. I'll press down on the gas but the car will not accelerate. After about 5 seconds of this the car will drive normal.
Any ideas?
Cel is on will get it scanned today.

Re: (yannerz)

If it was my car here's what I would do.
I would go online, find the cheapest price, probably germanautoparts.com or mjmautohaus.com (best OEM replacement parts bar-none) and purchase both 02 sensors and a catalytic converter.

The P0420 is a Cat code possibly caused by a bad O2 sensor, and the other code being bank 1 system too rich can also be caused by a bad 02 sensor. Bad 02 sensors exponentially ruin the catalytic converter over time. http://****************.com/smile/emthup.gif
