Power Loss

[bwneilson]

I have a 53 Avensis 1.8 petrol and it keeps losing power intermittently. I have to switch off and restart then it goes ok. No warning lights appear. It has been in 2 Toyota dealers for diagnostics check with no faults found. Today it happened again and the error codes appearing are P0300, P0420 & P1305.

I am of the opinion that it is a problem with petrol feed. Any input would be appreciated

the first thing is to understand total millage .

as far as know the fuel filter/pump/level sensor (one unit) is due to change by 180k kms

but you must to decode these codes .

cheers

car has done 125K miles. I have had it for 2 years . problem has been ongoing now for just over a year. I'm convinced ita a fuel problem but 2 toyota & 2 other garages can find no probs

P0300 code says Random /Multiple Cylinder Misfire

P0420 code says Cat efficiency below threshold B2

P1305 code says Igniter Circuit fault #2
