Good day house, I'm quite new in this forum and I need help from anyone before I make a wrong decision.

My honda accord 2003 v6 #EOD has been having some issues for some time and I need help.

Symptoms include;

Improper gear transmission and poor acceleration,
Car going off when break is applied sometimes,
Vibration when matching the break
And some occasional sound in the engine when the Ac is on and the compressor pics up.

I scanned the car with a friends scanner and got the following error codes
P0141 - power train - generic - O2 Sensor Heater Circuit (Bank 1, Sensor 2)
P0161 - power train - generic - O2 Sensor Heater Circuit (Bank 2, Sensor 2)
P2243 - power train - O2 sensor Reference Voltage Circuit/Open (Bank 1 Sensor 1)
P0154 - power train - O2 Sensor Circuit No Activity Detected (Bank 2 Sensor 1)
P0325 - power train - Knock Sensor 1 Circuit (Bank 1 or Single Sensor)
P2240 - power train

On mechanics advise,
I've changed ATF and engine oil
Changed plugs
Changed fuel pumps

And still no solution.

So please I need help from anyone

Your problem are so numerous. Clear those codes with your scan tool.drive the car for 30mins and rescan the car to see which codes are left there.

As for your sluggish movement: I always tell my clients honda does not have a substitute for transmission oil. The recommended trasnmission oil is Dw-1 or z1. Am very sure those road side mechanics have done some Acradabada to your sweet v6 honda accord

As for your car going off (stalling): a complete tune up is needed I.e change spark plugs, service injector noozles, check fuel pump pressure, check fuel filter, now according to you you said you have changed the spark plugs and fuel pump

Now a quick question as regards this was it the complete fuel pump module that was changed or just the pump? Did you get the recommended spark plugs?

As for the sound you hear in your engine when the Ac is on take it down to your Ac technician

My 5cents. Don't thank me now thank me later

Thanks for the reply, but pls do u know any place I can take this to get checked I'm thinking of changing mechanics. So I'm looking for recommendations.

And if you're into this, I'd prefer to bring it to you

Call this number 08165520837 or 08156087872

Never forget your air induction system as it has grate impact on your engine performance and also the stalling.

Your throttle body should not be left out of the tune up.

Also use a recommended spark plugs as it was advice by Mayor2013.

But note that if the code you get still comes back you need to do a trouble shooting and change the parts if need be, because bad O2 sensor will only dump more fuel into the system which will not be completely burnt and causes carbon build up. The after effect of this is what you are experiencing now.

I used the z1 ATF and NGk plugs, I'll call those numbers, but is the person in Abuja

Use your scanner and clear the codes then drive the car for sometime and rescan. If the code pulls up again, your O2 sensor may be bad. For the Spark plugs use NGK Iridum IZFR6K-11. For the tranny oil use DW-1 or Z1(difficult to get these days). For the vibration when braking, check your alignment/knuckle.

NOTE: 2003 ACCORD V6 IS A PROBLEM-FREE CAR IF YOU DO THE RIGHT MAINTENANCE. DON'T ALLOW THOSE QUACKS TO RUIN THAT CAR FOR YOU.

Please any idea how much it'll cost me to change those sensors?
