Thanks for your response.

The P0420 is showing because there is no catalyst.
It has the k24 engine.

The fuel economy on the dash suddenly drops from 19mpg average to 6.5mpg and black smoke starts.

you will need to by O2 spacer, your issues stems from the catalyst inefficiency code, either you buy a replacement catalyst or get an O2 spacer to fool the ECU.

Appreciate this sir. Will inquire on how to get that done. Are you in Lagos?

Abbeyismo:
Your top cylinder did the mechanic resurface it when they remove it or not?

Yes. It was resurface.......

Please how can I get O2 spacers for my Honda pilot 2007, it gives p0420 and p0430 codes simultaneously.

No

You can buy already made with small catalyst converter embedded
Enter mkt and confirm price

Does this have any side effects?

I've read on here about anything not actual catalyst causing a blockage and eventually damaging the engine.

Spacer does not in anyway clog the flow of exhaust it is just like a threading for the bolting of Oxygen sensor. The spacer moves the O2 sensor away from the exhaust gas pathway just enough to fool the ECU that the catalyst is still very okay. Just Google O2 spacer you will learn something, infact you can even have a panel\welder do one for you not a must to buy the expensive OEM units for outdated cars.

This is very appreciated sir. Thanks a lot. Will drop feedback once done.

Black smoke means that your car is pouring too much fuel into your engine and the intake air is not commensurate.

I'm not sure this has to do with "no catalyst" as catalyst is primarily for emission control (I stand to be corrected).

If I were you, I will start from checking my fuel pressure and then proceed to check if the injectors are leaking.

You can also check MAF sensor (if your car has one).

Also, do a live data stream with your OBDII scanner. Check your O2 sensor readings and your fuel trims. That should be a guide also.

Thanks for this. Will definitely run all these tests

My Corolla 2004 make this krarara sound when I'm about to throttle hard, but stops once the car gathers momentum or I remove leg from throttle at the instance of the sound.

Again, trying to climb steep hill, the car vibrates, but after climbing it picks momentum without any issues.

What the likely cause of this?

Is it advisable to buy a Corolla with top noise issue? Can it be fixed perfectly. A mechanic advice it can’t be fixed that I should just get an engine.

Top cylinder is gone.if u buy.just park the car at home and buy another top cylinder. If u attempt to repair it. U go hail

Okay thanks, what is the cost of top cylinder?

What the likely cause of this?

From your description, your Toyota Corolla 2004 showing a “krarara” sound when throttling hard and vibration on steep hills is likely caused by one or a combination of the following:
1. Worn or loose engine mounts: This can cause vibration under load, especially when climbing or accelerating hard.
2. Transmission or clutch issues: If the clutch is slipping or the transmission is struggling, it can make noise and cause vibration until the car gains momentum.
3. Exhaust system components: Loose heat shields or worn exhaust mounts can produce a rattling or “krarara” sound under acceleration.
4. Suspension or drive shaft issues: Worn CV joints, bushings, or shock absorbers can also cause vibration during load or steep climbs.

Recommended Action:
• Inspect engine mounts and transmission for wear.
• Check clutch operation if manual, or torque converter if automatic.
• Examine exhaust system for loose parts.
• Inspect suspension and drive shafts for worn components.

For a precise diagnosis and fix, we recommend bringing your vehicle in for a full inspection.

Hi guys, I keep finding water at the footrest of both front seats of my Rav 4 2004, it happens when it rains. Any idea where the water might be coming from?

Have you fixed this? I just did in my Rav4, it's an easy fix that you can do.

Leak from the moonroof or sunroof area is usually caused by a blocked or clogged drain. When you open your moonroof, you will see a small hole on both sides at the front. That is where water passes through to the floor. If it is blocked, the water will enter inside through any available opening.

So just clear it. Watch the video below for a demonstration. I used a broomstick to do mine, then poured water after that and it flowed easily.

I'm having same issue but at the left back floor mat, and in the booth, mine is 2012 corolla, I don't know where it enters especially the left back floor.

If you had cared to read further downward, you'd had noticed I gave him the solution and I'm very sure if he did what I asked him to do, the issue won't be present any more.

That is how a studebaker of 1945 does na. It's absolutely normal.

I think you did not get the complains correctly.
The car does not have that high initial rev at cold start up any more. There is something wrong somewhere since it is not how the car was operating formally.

Name of car, model of car, year production, engine type, recent repair carried out just before the anomaly started?

None of these important details were given

Water ingress into the engine. Have a mechanic open the plugs and check.

Good Evening guys, I have a 2004 Honda Accord EOD, the gear is jerking when switching to gear 1 & 2 but after that it move well but recently the gear fail at times that i need to off the engine and wait for some second then start again, please i need help on how to overcome this
