Hi, I have 2003 Toyota Matrix that has 1ZZ-FE. The car has been sitting long time, now I'm trying to make it run good so I can sell it.
(0:19~ 0:24 Loud and Clear) So while this car is in drive around 2000 RPM, it's making rattling or knocking noise. I don't know how to describe it.

But when it's in Park, and I rev it up, it doesn't make any noise.
Also in low RPM, it start to struggle. Like almost stalling like. and Whenever I put in in reverse, RPM drops like crazy.
I recently changed Alternator/ Battery / Spark plug (BTW there was oil inside) / Valve cover Gasket for begin my maintenance/repair process.
Any idea where I should check next? Is it engine or transmission? I mean the noise coming from driver side which is where transmission is located I believe...
The crappiest part is that it's only throwing misfire code sometime here and there. and it goes away.
This car is full of problems but 3 Main problems I have right now is that...
1) Rough Idle. (Car Idles between 1K ~ 500RPM it acts like it will stall any time, and symptom gets worse when in gear)
2) Weird noise knock or rattling noise in 2000RPM~3000RPM range
3) Oil leaks in Spark Plug well Even I replaced valve cover gasket (One piece with O-Ring). I believe this threw few misfire codes. (First I thought codes were caused by alternator. My mustang GT I used own had a misfire problem because of alternator)
I'm gonna test if it has a blown head gasket. I HOPE IT DOESN'T HAVE IT. (I checked radiator cap and stuff but no milky stuff yet. Gotta actually test it with proper tool)
