When I put it on a tester, it reads codes for knock sensor and maf sensor. Last week the crankshaft sensor read bad. Changed it and still just as bad at misfiring. Took my maf sensor out. It's practically bran new with no signs of damage

I took it to O'Reillys to get the rest. I don't have specific numbers. Just know that it's show up maf sensor and knock sensor. I had two separate codes for the maf sensor

We need to know what is going on with the car now so the codes needs to be cleared and then the car driven until it sets the codes again and then get the numbers.
