Good day everyone,my lexus es 350 car if I don't warm the car for like 15mins in the morning it won't enter reverse when driving when the car is hot it won't enters gear 3 it starts to rev high only gear one and two is working my Kazim said it's fiber and the gear can be repaired pls I need ur advise thank you

The scan results

Nomerci:
Nothing like fibre. I learnt the hard way with my is250. Theychanged the fibre.after that the gear started making loud bang in between witches.later found out they did not calibrate the wheels.its not like its something i could just take
spanner and jack and gboom.problem solved.men just buy another gear. They might buy it as scrap for 50k.use the money to do something meaningful. Buy another gear or sell as is.i saw the same lexus es350.do overheating again today.

Good morning, everyone.

I drive a 2008 RX350 that runs perfectly well — the engine is quiet and performs like a turbo.

However, there’s one issue that’s been bothering me. The car starts instantly in the morning, but if I turn it off and try to start it again after about 30 minutes, it usually takes 2–3 attempts before it comes on. Interestingly, if I keep the key turned (cranking) during the first attempt (after it has been turned off for a while), it eventually starts.

Does anyone know what could be causing this?

Hello all.

Pls I got the following code after scanning my car.

Pls what next should I do?

Chidimercy:
Please house my ES330 2005 Shows this code when I scanned it. I noticed a little jerk in the car this morning. Please can someone help me explain the codes:

1) P0303 Cylinder 3 Misfire detected
2) P0420 Catalyst System Efficiency Below Threshold. Bank 1
3) P0430 Catalyst System Efficiency Below Threshold. Bank 2
4) P2238 02 Sensor Positive Current Control Circuit low (Bank 1 Sensor 1)
5) P2241 02 Sensor Positive Current Control Circuit low (Bank 2 Sensor 1)


I need help house, what’s wrong with my car?

Hello and thank you for sharing your concern regarding your 2005 Lexus ES330. We’ve carefully reviewed the trouble codes you posted, as well as the symptom of the slight jerk you noticed. Here’s a structured analysis and professional guidance:

⸻

Technical Breakdown (Diagnostic Insight)

1️⃣ P0303 – Cylinder 3 Misfire Detected
• Likely Causes: Faulty spark plug, ignition coil, or fuel injector specific to cylinder 3. Possible compression or internal engine issues if the components are healthy.
• Symptoms: Engine jerk, rough idling, slight loss of power, uneven acceleration.
• Professional Fix Steps: Inspect and, if required, replace spark plug and ignition coil for cylinder 3. Test the fuel injector for proper spray pattern and operation. Conduct a compression test if misfire persists.

2️⃣ P0420 & P0430 – Catalyst System Efficiency Below Threshold (Banks 1 & 2)
• Likely Causes: Aging or partially clogged catalytic converters. Often secondary to persistent cylinder misfires causing unburnt fuel to enter the exhaust.
• Symptoms: Check engine light, reduced fuel efficiency, possible unusual exhaust odor.
• Professional Fix Steps: Inspect catalytic converters and test downstream O2 sensors. Replace converters only if efficiency is below threshold after upstream engine issues are resolved.

3️⃣ P2238 & P2241 – O2 Sensor Positive Current Control Circuit Low (Bank 1 & 2, Sensor 1)
• Likely Causes: Faulty upstream O2 sensors, wiring harness damage, or ECM signal issues.
• Symptoms: Poor fuel mixture, jerking, emission errors, reduced engine efficiency.
• Professional Fix Steps: Test upstream O2 sensors’ voltage and current output. Inspect wiring for corrosion or damage. Replace faulty sensors as required.

⚙️ Ryan Automotive Workshop Professional Take

In our experience with ES330 models (2003–2006), a single cylinder misfire, such as the P0303 you are seeing, frequently triggers multiple O2 sensor and catalytic efficiency codes. Attempting catalytic converter replacement or O2 sensor repair before addressing the root misfire often leads to unnecessary costs.

Our recommended approach:
1. Diagnose and resolve the cylinder 3 misfire first.
2. Retest O2 sensors and catalytic efficiency.
3. Proceed with component replacements only if diagnostics confirm failure.

This sequential method ensures precision, reduces unnecessary expenses, and restores smooth engine performance.

Thanks for your contribution, but I am not based in Lagos, would have come around for a fixing.

Meklex:
What's the best affordable oil I can use for my car, ES 300?

Louiscars:
MICKING 5w30, 6L would work just fine. ( I want to believe you don’t have oil burn issues and you know the former oil weight that was used for the car )

Meklex:
No burn issues. 5w30 is the oil weight and quantity is 5L.

I don't think I can find this oil brand here in Anambra, but I will check. Do you know how much it's currently sold.

Are there other recommendations?

Hello friends, my rx400h tailgate is failing. If I tried to open from key or from the button inside the car but it will refuse to open until after I've run the car for like 10 minutes. Does it requires recalibrating after removing car battery because that's the only thing I did that could I suspect.

Also, the gear handle is stiff when changing from park to reverse to neutral and to drive and back.

Thanks.

For thr tailgate, check the tailgate struts, they may be weak or worn out, also, check the auto tail gate opening and closing mechanism, it may be worn out.
For the gear shifter, you should check the shift cable that runs from the shifter stick to the transmission.

AfDapone:
Thanks @kingreign

kingreign:
You're welcome sir

If you're in Abuja feel free to contact me to help fix it.
