My Adventure 1.6 RPM has started to idle between 1000 to 2000 RPM. It stays there no matter what and after some time (between 10 seconds to 5 minutes) drops back to 800 RPM. Also issues with TEMP needle. It is constant at half mark and at time a bit above. Tried AC to check if the temp needle will come down but it did not. I checked on web that for RPM issue we need to change throttel body and air filter and speed console. Not sure what to do, any advise? Thanks, -Sheetal - - - Merged Post - - - forgot to add that fuel (indicator) gauge is not showing correct values. What part to replace to fix the issue.
