might be running rich it was a trick i did
with the 9th injector whin i had one made
my car sound lumpy

 

I had a similar problem with my car and it was the MAF that was the problem, one of the hook that hold the wire inside it was broken and somehow it made my engine sound like I had a lumpy cam. And the ECM never registered any code ??????
