2007 Lexus IS 250 sputtering


Asked by Aug 22, 2016 at 11:42 AM

Question type: Maintenance & Repair

I gave my son in the Navy a 2007 Lexus IS
250 with 125k on it. It up to 140k and been
running great. It just started sputtering with
accellerate. Fuel injection?

1 Answer


Maybe. Try checking for trouble codes. Sputtering could be fuel pump, dirty filter, dirty injectors. If you plan to keep it, give it a tune up (new plugs/wires), clean all the filters and sensors (maf/map) TPS, check/clean PCV & EGR. When you have the plugs out check their condition for carbon buildup.
