so occasionally would notice RPMs revving to 4000 when hitting 60. Would have to let off the gas for it to go into gear . This only happened once or so a week max and only once when starting to drive. 2 weeks ago (1100 miles from home) it started revving at all speeds had almost no acceleration would not go up hill. Got codes p0420, p0133. I got new battery as it was bad, new sparkplugs, did cataclense and check engine light went off and I was able to make it from Denver to Lubbock with no problems. In Lubbock the revving issue came back and car would not go over 50 flat, 45 hills. I did cataclense again and limped the remaining 750 miles to Rockport. We changed the catalytic converter and O2 sensors. I am still having issues. I can get to 70 but mpg is 12-16 and still revving when changing gears. I am still throwing p0133. Transmission fluid nice and pink, no obvious exhaust leaks detected. I have to leave for a 2k road trip to new job tomorrow or next day. What can I do next ? Would hew TPS or cleaning the MAF help?
