I’m sorry if I couldn’t find the thread with this information but I did try…I’ve had my gx460 for about a year. 175k when I got and serviced transmission then. Getting codes once and have been told I need to do it again. It surges under load. Oddly I cleaned the MAF and put a new OEM air filter in and it ran unbelievably until I went out of town for a week..when I came back..codes upon start up. I ordered aisin ws and am looking at filters. Could I get a recommendation pls. Thanks!
