Any misfire on the car? Value for the mass airflow looks high if on idle. Does engine idle well?

No misfire... Engine idles well, btw 800 & 850rpm The screenshot with mass airflow is freeze frame for the P0420 code

mayor2013:
If I may come in here the actual values were captured when your car was on motion?

The first screenshoot were at idle.. But even on motion.. The value fluctuate but mostly on the negative side

honmusa:
It is quite ok if you have a single digit negative fuel trim ,your car powertrain air fuel mixture is quite ok.What become an issue is if the single digit turns to double digit wether on positive side(lean) or (rich).

I have seen it as high as negative 13

AutoElectNG:
I will address your question soon.

This is an OBD II issue.

I think is is wrong to call that MIL code just.

OBD II considers emissions issues more important than drivability issues.

The catalytic converter is a major part of your vehicle's emission control system.

Expect an in-depth explanation of the issues later.

To help me treat the issues as they affect your vehicle in particular and not just this code in general

Did you buy this vehicle brand new or is it new to you?
What is it's mileage?
How long have you had this problem?
Was any repair made before you had this problem?
Do you have any drivability issues?
Or is the MIL on but no drivability issues/complaints?
Can I have your Freeze Frame Data?
Current Parameter Display information?

If I can have this information, I will personalize the response.

I can see you have your own OBD II Scanner! That's a big plus!!

How long have you had this problem? I dunno, I don't usually check fuel trim

Or is the MIL on but no drivability issues/complaints? No drivability issue

Can I have your Freeze Frame Data?
Current Parameter Display information?

I don't bother with FAR at all as it'll lead to gray or loss of hair.

Good fuel, good plugs, etc no CEL and I'm a happy camper.

Hahahaha true that, the car drives fine Sha, no issues.. Was just playing around with my Bluetooth(toy) scanner, when I noticed the fuel trims, decided find out more about it

Good days gurus, please what are the causes of negative fuel trim? On but short term & long term, from my little research online, means the engine is running rich meaning higher fuel consumption, the car is Honda accord 2006 i4, the only MIL code on is catalyst code P0420

Trust me U got death wobble that's how it starts . The fact that your vibration stops b4 and after a certain speed each time means something is lose amongst your suspension . It took me nearly 9 months to fix this.it could be as simple as replacing a bushing.it would get worse if you fail to.fix it.

EgunMogaji:
If it's wobbling that you can feel then I bet that it's a bad tire.

GAZZUZZ:
put car on a stand, release parking brakes, turn by hand really fast and watch wheel. Or take tyres for wheel balance "again"

Semantics. All nah 'S'

Thanks everyone.. One of my rear tyres was twisted or "wonble" as the vulcaniser called it.. I replaced it temporarily with one of the old tyres I changed..
But please what is the cause twisted tyre, is any defect on the car a factor? Or just defective tyre

Ok I have had same expirience with one of my BMW back in the days, mine was bellow 60mph, it was as a result of waht is called death wobble.U can search on youtube and see how it relates to your car, could be Hub or bearing.

Hahaha Bros, after researching on the death wobble.. I don't think mine is that serious.. Any way thanks for your input... Learnt something new

GAZZUZZ:

Did not do wheel balancing before, could that be the cause?

GAZZUZZ:

Thanks but how do I identify a twisted tyre? And any remedy?

Lexusgs430:
Semantics. All nah 'S'

Alright Bro.. Will check that, overlooked it because I felt it should make noise if broken

Lexusgs430:
Checked your springs for any break?

Shocks?

GAZZUZZ:
It is essential you state the type of vehicle you use, with full description (4wheel drive, front wheel etc) als the type of tyres you bought (brand new, toks, nigerian used ) that way I know what to rule out in a query this vague.

Oga GAZZUZZ It's tokunbo tyres and the car is Honda accord 2006, front wheel drive....

The car is Honda accord 2006, Whenever am driving at speeds below 30mph I feel the car kind off wobbling from the back, but once i speed up, I don't feel it any more, I just changed my tires and I did alignment about 2 weeks ago, please what could be the cause
