SO i thought i fixed my low rpm problem for the moment until I was driving around this morning. I was cruising and i noticed around 3000 rpm my engine had a rattle to it. It was more noticeable in 1st and 2nd. I was about to stop and check it out when all of a sudden I stall at a stoplight and my oil light goes on. I was about 2 blocks from home so i decided to make it home to be safe and figure it out from there. On my struggle home the engine rattle gets louder (could it be knocking?) and louder and Im pretty sure its hurting the engine . Anyone familiar with these symptoms? Any help is appreciated!

recent work done:
-cleaned tb
-ran 91 gas with injection cleaner
-cleaned IACV

 

turn it off.... check the oil level...

 

Check your IACV bolts, make sure they didn't come loose, if they come loose your car will go crazy.
