Hello Nairalanders,
I have a 2012 inline 4 Honda Accord coupe, car has been an absolute thrill, zero issues, no stress until three months back, travelled out of town for work, spent a little of three weeks, car was undriven during the whole time. came back and all hell broke loose, first AC wouldn't changed the in cabin filter, Flushed and refilled, Problem solved, had issues cranking the car, battery was on its way out, so I replaced. Issue now is the car is slow as f**k, overtaking and hill climbing is such a chore, especially when the engine is under load(AC on).
Yes i have scanned, yes check engine is on. Don't have the results as i wasn't there but mech said its only cold start sensor that appeared under powertrain codes.

Its a little better if i put the selector in D3, As advised by my mechanic i've replaced the following:
1. Injector nozzles(All 4) with a complete assembly from oyingbo
2. Cleaned throttle body(process was a b***h because i took forever to successfully relearn the correct idle position )
3. Changed all 4 spark plugs twice(Honda branded first, NGK next)
4. Two faulty distributor wires
5. Transmission Fluid Change(Did the recommended flush and refill x3 couldnt get DW1 for the 2nd but have drained and refilled with DW1)
6. Fuel pump assembly
7. Throttle Position sensor
8. Air filter
Even after the car still accelerates like a diesel truck, mech is tired says to just manage it like that. I'm a loyalty person so i haven't changed mechanics but i'd be open to doing just about anything to solve this problem. I'm in Lagos, Gbagada to be precise.
NB:
Noticed that my upstream 02 sensor is disconnected, plug is broken so i couldn't connect myself, took it to my mechanic and he says replace, Paid twice but he say's he can't get a working one and advised against going myself because i'd be easily swindled on a part like that, read about the open and closed loop operation of oxygen sensors so could this be the culprit?

Change the Mass air Flow meter, and also the o2 sensor. You can contact Gazzuzz here, look for his contact.

samintegrity:


Why do I even feel that mech is the one scamming you sir..

He obviously doesn't have an idea of what's wrong, hence the need to keep pushing money.

Moreso, a simple obd scan should at least give you a clear direction sir..

That said, it's a rewirer work sef not your mech..

Structuralman:
How is the fuel consumption after you parked the car for 3 weeks??

adanny01:
Also check all your engine mounts and especially the rear engine mount.

I experience smoother gear shifts and better acceleration when i change a bad rear mount.

GAZZUZZ:


It would not hurt to check.

nurey:
Change maf sensor

Clean or change the air filter

Do a relearn for the system

Fix the disconnected sensor

Then check condition of vehicle and scan also b4 touching injector and other sensitive sensors

Thanks chief
Considered it but his place is way out of my way, not really conversant with the mainland but i may just head over there tomorrow.

speedfreak:

Buying a new Maf and 02 sensor this morning, the relearn is it the normal "start with all loads off and idle till the fans circle once" or another?

Update:
Replaced both MAF sensor and the upstream 02 sensor, sluggishness disappeared immediately , still have a glowing check engine light but I'll scan and troubleshoot on Saturday. Thanks for the recommendations

Nice, run from that your mechanic first
