still rattles
ok so here is the deal. my car sounds like a tin can full of marbles when i hit high rpms. I was told this was a common occurrence by you good people on this forum that it is most likely my cat. Had that checked out and my cat is fine, heat sheild is not cracked. So if anyone can take a stab at what direction i should go with this then please let me know

It's a Cavalier
I remember mine used to do it. This is when they first coined the term "marbles in a can".
The dealership, not knowing how to diagnose the problem, changed out the heat sheilds, entire catback, cats, intake, motor mounts... and it would throw lean codes all the time.

Can be High Carbon Build UP..
Spark Plugs OK?
Coils OK?
Leads OK?
Use Premium Gas ONLY?
Throttle Body Coolant By Pass Can Help.

The RENESIS is a high Compression engine that requires the premium gas.
Some say the low grade gas adds to carbon build up.
Yes. look in the DIY section for the TB BY Pass.

I had 20K on mine when my first MIAC(Detonation) showed up. I was using reg gas so I went to mid or prem and the problem went away. Then there was the(one minute) Throttle Body By Pass that was said to fix it. I did it, ran reg again and no MIAC, but it was winter. Summer came and it would come back on days over seventy degrees. I then put plugs, coils, wires in and had compression checked. One rotor was low so the dealer did there own test and said there was no problem with compression. It felt Stronger now and I could run reg again? They did not tell me so but I feel I just got the free de-carbon done. I enjoyed it and wondered why they did not tell me they cleaned it out. After a few thousand miles it was back so I'm on mid or prem no problem.

Run two tanks of at least 91(if not 93) and then tell us how is doing. Seriously, why are you even trying to run 85??????

the highest they got out here in butt **** no where Montana is 91. I will give that a try and see how it runs. I was told that the 85 grade would not make a difference on my car. 91 was just better for gas mileage on road trips. I guess not all of us can be perfect. haha
