Hey Guys!
Having some trouble with my 2000 VVTI corolla. i'll admit she has seen a few miles (177k) but I feel she can do a good few more.

I'm getting undocumented codes, 3 in fact
1346H/4934
301H/769
300H/768

The car is spluttering with a major lack of power. i thnk only 3/4 cylinders are going,hence the power loss. i've been googling these codes but cannot find any information about my problem as apparently these undocumented codes are not legitimate to my model. Maybe thought somebody here might have some sort of idea, i would really appreciate some help.

Thanks guys

The 1346 is a code to change engine oil, the 301 in # 1 cylinder misfire and the 300 is mutilable cylinder misfire

don't know how you go tthose codes but 300 and 301 are misfire codes, have fuel pressure checked and then have a pro look at car as misfires are very hard to diagnose as it can be a sensor or a basic engine problem. that is cheapest way to fix. we dont' have that small of an engine in US but this may have a timing belt jumped or ecm and recommended replacement for belt and tensioner is 90,000miles which you are well over.

Was a coil pack, was easy and inexpensive to replace it, but I got the car a full service too while I was at it.

Thanks again guys
