2002 Trailblazer Acts like cat. converter is clogged, but only when in gear.


It may be worth your while to have an exhaust back-pressure test done to make sure your converter isn't plugged. When the vehicle is in neutral, there is very little load on the engine, so a blocked exhaust may not be as apparent as it would be in gear.

the running issue seems to be the convertor clogging up. need to have backpressure test done to see for sure. the electrical issue sounds like the ignition switch or the orange ,pink,or yellow wire going to the switch. both are common problems with the trailblazer.NOTE if the vehicle has less than 80000 miles the convertor will still be under factory warranty (EPA guidelines)

Hi Eabyrd05.
It's possible that you have a Starter or Flywheel/Flex-plate issue. Your starter Bendix may not be completely disengaging from the flywheel like it should. I would take it to a mechanic that you trust and have them pull the starter and look at both the Flywheel/Flex-plate, Starter Bendix and solenoid. Hope this helps.

It sounds like you maybe low on freon and your a\c compressor is kicking in and out at lower RPM's because of low pressure,then you build enough pressure to keep it running at higher RPM's.

4 wheel drive is binding in 2002 trailblazer


the trailblazers are designed to shift from 2 wheel to AWD on the fly. BUT NOT TO EITHER OF THE 4 WHEEL OPTIONS. I'd suggest you get it to a mechanic to evaluate the damages.
