I cleaned my MAF sensor Sunday, seemed to run better, then got home Wednesday morning and now it will start running really rough at idle occasionally and sometimes when I stop to park or at a red light. What's wrong? Is it in the computer, ignition control module? Also my check engine light has stopped working altogether. Someone offer me some solutions please. Thanks

 

Is it throwing any codes? If your check engine light is actually not working verses not being lit up, then it will still read a code. I would grab a OBDII reader and start there.
