01 corolla engine problem
my corolla starts fine but as soon as its idling it shakes violently and barely keeps itself running. when going up hills it loses all power. i cleaned the ocv valve and the pcv valve and changed the spark plugs. the only codes showing are misfires and occasionally an oxygen sensor because the car burns oil pretty bad too.. any help would be good
check your air flow meter !!!sorry for my english is too bad !!
I agree, the air flow metre would be good place to start. Also make sure that you take it for regular oil changes, and it may also need a tune up. I have an '02 with 39K miles that shook violently when my friend put 87 petrol into it instead of 89 (these cars also seem to be temperamental about petrol. I fill up 89 and every 4 times put 93.) Also make sure the fuel lines aren't clogged. This happens if the car has been run on empty a lot. My friend's '01 (with 178K miles), idled badly too, until I put good petrol in it. Best bet though: fuel lines and tune up.
Mine was the same and I increased the RPM buy increasing the gas flow
Either Mass Air Flow Sensor or the Air-Fuel Ratio Sensor. They are the entrance and the exit of the engine.
