Need a little help with diagnostic, trying to fix it

Recommended Posts

So what my es300 2003 is doing is it takes a little more rpm to go the same speed, and a noticeable about more press of the pedal. 

 

I replaced the fuel filter, cleaned the fuel injectors with gas cleaner, and gave it an oil treatment. 

 

It also shifts weird because of it, since the ecu is trying to Rev match but it's not used to what's going on. 

 

I've been trying to figure it out myself, I'm thinking maybe just replace injectors or a throttle position sensor. But the position sensor wouldn't explain the lack of power as well. And the lack of power is inconsistent. Sometimes there's power, sometimes there isn't power. 

 

Any help appreciated!!

Is your check engine light on? This could be a transmission issue. How does your transmission look?

      2003 ES300 - The passenger side light on the trunk is not lighting and indicator on dash shows it is not working. I found the replacement bulb (7440 single filament) but have no idea of how to remove trunk liner for access to the bulb. Trunk liner seems to be held in place with plastic push pins and I don't want to break any. Any advice will be appreciated.

      What do you all suggest as the best pure synthetic oil for a 2003 ES 300 with 209,000 miles? Runs perfectly with a very small (weekly drip) using Mobil 1 (5W-20). Also, what filter is recommended. Located in NC Piedmont region. Car is only driven <5000 miles a year.
