accord cw1
My accord 2.0 vtec has a stutter or hesitation in two scenarios, when i am cruising with constant speed and add a bit of gas, light acceleration, it hesitates a bit or stutters for split second and then it starts to build up speed normally, pretty hard to replicate and hard to catch anything via obd scanner on my phone. Other scenario is when i give it full gas pedal to floor it has a similar power loss/stutter at about 3500-4000rpm. Both are more noticeable when having a/c on.

Car has new oil and all filters, new ngk iridium spark plugs, no check engine light, valve adjustment done 3 weeks ago and it didn't fix this problem, i have also cleaned intake valve, maf, map and egr (which shows 99% error in car scanner app, not sure what it means). car has 113.000km on the clock, only other problem i have is heavy oil usage.

Does anyone have any idea where and how to start investigating this?

Thanks in advance
 
Only a diesel here, but I had scrape/wear marks on the wiper area of the throttle position sensor (about 4.30 on the image) that meant the car would have a wobble if I left the pedal for too long at a certain position

After seven years of using good electricval cleaner on the contacts outside and in I replaced it.

Abouty £30 from memory and while I don't thrash the car, I have no reason to doubt the worn item wasn't the cause of some issues in my time with her
