Lexus Troubleshooting Questions? Ask a Lexus Expert
Hi Im David, I'll try and help you figure out the issue that your are having. How is the cars idle? smooth or rough?
I think it would be a good idea to see if all the injectors are firing. if you can access the injectors while the engine is running, listen to each of them with a stethoscope(cheap at harbor freight) make sure each are clicking at the same rate while someone gives the vehicles rpms.
I would also have the fuel pressure monitored during acceleration to see if it stays steady
let me know how it turns out.
hows it going with your vehicle?
did you monitor the fuel pressure during acceleration?
