2003 Lexus ES300 Issues

Question

Hi, Scotty!I have an issue with a 2003 Lexus Es300. I’ve had the car since high school, and it was my grandmother's (purchased new in 2002). At any rate, shamefully, I have let the car sit in the driveway for two years. When I parked it I put fuel stabilizer in the tank. I went to start it, and it had a litany of issues. One, which is a no-brainer, harmful gas (it had a full tank of 93); misfires (coils and plugs replaced); O2 sensor issues (downstream replaced-Denso); one of the three cats replaced; oil change (ofc an oil filter), I only run synthetic; and other miscellaneous items. However, the car ran rough! It has an issue idling; I addressed the IAC, put on a new TPS, and calibrated the TPS using my multimeter (0.60, what I am told, and I could be wrong). Still, there’s an issue: it jerks at idle. The issue before was idling too low; now, it idles fine but jerks. I did the “TPS RELEARN” and scanned it, but there is still an issue. I am at my wits end for my feted Lexus. It was sitting because i drive my  POS ‘15 Ram Ecodiesel primarily. It’s a nightmare, and that’s a story for another time. I hope I have reached a suitable medium for contacting you! I hope you’re well. I’ve been a long-time subscriber to your YouTube channel. I hope to hear from you soon. Continue to take care!-Jo

All right, here's the problem. They sit like that. The fuel injection system generally gets all crap out. You definitely have to change the fuel filter. It's probably clogged up. You may have to change the fuel pump. And I would advise trying some of my friend. Bernie's ATS fuel injector cleaner just Google Bernie Albuquerque ATS fuel injection cleaner. Good luck!
