Avensis Vvti starting Problem

Hi All, I have a 2005 Avensis 1.8 vvti which has developed an intermittent starting problem. Car seems to misfire while trying to start, but up to now will start eventually. This can happen when hot or cold. Car runs fine once it starts, but fuel consumption appears to have increased. Only fault code code on OBDII reader…

Hi All,

I have a 2005 Avensis 1.8 vvti which has developed an intermittent starting problem.

Car seems to misfire while trying to start, but up to now will start eventually.

This can happen when hot or cold. Car runs fine once it starts, but fuel consumption appears to have increased. Only fault code code on OBDII reader is P0420 "Catalyst System efficiency below threshold". I think this may be caused by whatever the starting problem is?

Recently cleaned MAF sensor, oil, oil and air filter replaced every 6k miles. Spark plugs replaced . Also repaired broken clip on air filter housing.

Car has done 250k+ miles and timing chain a bit noisy when starting from cold.

Any ideas?

That P0420 i dont think would cause your starting issue i had that code over 3 years on my last avensis and didnt make a difference only main dealer wanted 800 to change the cat!
