I have a 2001 firebird and sometimes when I start it the Check Engine Light blinks and it idles rough for about a min.
also it looses power sometimes I have put a new full pump on it but it didn't help !!

Thanks for any help!!!

 

if it gives you a check engine light go have the code read, may be o2 sensor or some easy fix. Advance and auto Zone check your codes free. Good luck

 

I replaced the o2 sensor ,and it didn't fix it , someone told me it was the Mass air flow sensor. I was wondering how I could look at a picture of it, I was looking on E-Bay but I have no clue what it looks like.

Thanks for any help !!!
