150000 miles Yaris 2011 poor acceleration and power fluctuations.

[Charlieclangers]

Hi , I purchased a Toyota Yaris 2011after owning it for just over 3 months. It has 99000 on the clock but mytotota paperwork says 15000 🤷🏼*♂️.we only got this after getting documents through from DVLA for vin but that's another story

ISSUE: I started to notice poor acceleration and a fluctuations in power when driving along in the same gear not.moving my foot from the accelerator.

GARAGE OPPION : Having taken it to a Toyota specialist there oppion is it needs a new timing chain. Having looked at my Toyota it said a new one had been fitted in December of 2019.They found no issues with exhaust pressure either which is something we had thought it might have been .

OUR OPPION : having read about it a bit online we've read about vvt solenoids causing similar issues with rpm fluctuation

SALIENT POINT: where in the engine would I find the vvt solenoid and dose anyone have any expiernce with similar issues on high milage Yaris . I get about 30mpg for city driving

Any advice or help would be greatly appreciated thanks in advance
