Hey guys, I have a 2000 Mazda Protege LX. I had a check engine light come one. Got the code. I did a couple things to the car and check engine light turns on and about a day turns back on
1) cleaned the MAF sensor
2) changed the air filter
after that it went away and then came back
1) changed the MAF sensor
check engine light turned off and after a day came back on
it was idling hard so I put fuel injector and changed the PCV Valve because it was idling high. Check engine light went away and now it’s back and it hasn’t even been 6 hours.
thanks guys
