1999 Saturn SL2 runs rough, check engine lights up but no obd codes found, smells like gas.?
As mentioned in the title, this Saturn is having some issues.
First, it runs like it has a bad motor or tranny mount. The entire car shakes, not violently, but shakes none the less. I am not 100% sure the mount is the issue, because I get the feeling it is running on only 3 cylinders.
Plugs and wires were just replaced. Plugs were fried, looked like they hadn't been changed in years.
The car idles high, about 1600-2000 rpms and smells like Gas.
The air filter was melted when I removed it, but the rest of the housing appears to be just fine.
I am not an expert, but it seems to me like the only thing that could cause a melted air filter would be if the combustion in one of the chambers was back blowing into the air intake.
But again, I am no expert.
Check engine light comes on, but resets when car is shut off. Does not report any ODB II codes for me to follow up on.
Any experts have any ideas? or other things to try?

ALL SATURN SL CARS burn oil pretty badly. Do a compression test to get an idea of the current state of the engine. I replaced a cylinder head on my old 97 SL2, that was about 400 for the rebuild head, 100 for a gasket kit, and about 1000 for labor, to give an idea on what major engine work is likely to cost on these cars.
It sounds like you got this recently and the previous owner didn't know how to take care of a Saturn.

Do you really want to know? The 1999 Saturn SL2 IS KNOWN for the engines to fail and use oil at about 145000 miles. Do a compression test on it. I'll bet one cylinder has no compression, and the others have low comp. Would cost about $900.00 and up to fix it, and the car is only worth $1400.00. Do the math.
