1997 Camry - I need to reset computer after fixing the car in order to pass inspection. Is it true that you have to drive 80 miles nonstop to reset computer?

fix problem for fail then do the [quick drive]reset if problem not repaired you can drive all you want and will not reset https://repairpal.com/how-to-perform-a-basic-drive-cycle

drive cycle is you need to drive it between 30-60 miles to make sure your computer relearns all the emissions sensors and then you can get it inspected

You may be able to disconnect the battery for a couple of hours to clear the trouble codes, but the correct method is to use a scanner or code reader. The light will stay on as long as trouble codes are stored in the computer.

yes this is true if you unhook the battery cables and tuch them togather for 2 min
this will reset the computer make sure you have the code for your raido becouse
it will reset the raido to
once you reset the computer dont drive it very far take it rite down and get it inspected
be for it comes back on/// also it might not come back on at all but this will work

hope this helps you
good luck

I'd have fuel pressure checked, and at the very least, replace fuel filter. Not unusual to get multiple misfire codes due to low fuel pressure, thus starving cylinder(s), and causing the misfire code(s).

Something is not fixed. Though you say you fixed them or had them fixed doesnt mean it is all good. Sometimes defective parts. Unhook the battery for a few min. Then reconnect it. The drive about 30 nonstop miles. The computer will be clear then the problem codes will be stored and the light will come back on. Then re read it

what were the codes? It may never reset until u fix it. Most codes aren't intermitten. Not more than 80 miles if doesn't reset then you need to fix problem.

Drive cycle has to do with normal everyday type of driving. So many stops, so many miles, fast driving, slow driving. My car went thru a drive cycle in about 38 miles on my way to work. My daughters took 3 days and about 78 miles. So just drive it like normal.

Could be MAJOR.

The clunking as you describe it could be you lost a main bearing or rod bearing.

Either way ya look at it, with that many miles and a "clunk"...its going to cost a good bit to get it fixed, or replace the motor.
