brighton98 Posted July 28, 2015 Share Posted July 28, 2015 Car bucks and surges on acceleration, wont' go over 30 mph. I'm also getting the rotten egg smell and had a P0420 several months ago. Could this be a plugged cat converter? Thanks. Link to comment Share on other sites More sharing options...
Fairtax4me Posted July 29, 2015 Share Posted July 29, 2015 Could be due to jumped timing. Cyls 1&3 are both passenger side. Link to comment Share on other sites More sharing options...
brighton98 Posted July 29, 2015 Author Share Posted July 29, 2015 I started it after it had cooled down for several hours and it ran fine. It surged at idle before, now it was smooth. Thats why I wondered if the catcon was blocked and heating up?? Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted July 29, 2015 Share Posted July 29, 2015 (edited) vacuum gauge might confirm exhaust blockage. you can search for a chart of stuff it can help with. could be a weak fuel pump or something with fuel? how many miles since the timing belt system was serviced?
