Have you tested the camshaft or crank sensor, often at times these two can get a little wily and intermittently malfunction.

P0300 Multiple Cylinder Misfire Detected

P0306 Cylinder 6 Misfire Detected

P0451 EVAP Pressure Sensor Range/Performance

I have no idea what those last two are. Typo, maybe?

Your first two codes could be caused by old spark plugs and/or leaking plug wires.

Your EVAP code could be a bad fuel tank pressure sensor or a malfunctioning EVAP system. With that code, if you remove your fuel cap and get a whoosing sound, then it is an issue with your EVAP system not properly venting the tank. If you don't get that sound, then the tank pressure sensor is bad.

Hi,
Looks like the drain hose from the aircondition/heater blower box is clogged or its been pulled out from the box or the drain hole flooring.
You could clean it by pulling out the rubber hose and get some flexible wire to insert inside the drain hose to unclogged it.
Years of water and dust have accumulated inside the drain, mold might have built up inside it.
Check on those and tell us what happened.

Hello and welcome to FixYa! If you have overheating problem, it can lead to multipleissues. You may be running on low coolant that's why the vehicle overheats. Ifthat's the case, please add coolant and make sure that it sits on the rightlevel, too much coolant can cause overheating too for coolant will overflow. The vehicle may have a faulty or worn out radiator blowermotor that's why it overheats. If that's the case then you will need a blowermotor replacement to resolve the issue. If the radiator is clogged with dirt and rusts this issueoccurs too. The coolant doesn't flow normally on the cooling system if it'sclogged. If that's the case, I strongly suggest that you have the radiatorflushed to drain out dirt and rusts. If you think that the radiator served youenough then it's better to have it replaced. Please do check the radiator hoses, If you have worn outhoses it can cause coolant leakage which can result to overheating. A tiny holeis good enough for the vehicle to overheat. A faulty thermostat sensor can cause the issue too. If youhave worn out thermostat, the fan may not trigger that's why the fan won't workwhen under stressed conditions. A blown radiator blower fuse can cause thisissue too so I suggest that you check the radiator blower fuse and replace itwhen necessary. What causes the radiator blower fan fuse to blow? It's becauseof a failing radiator blower motor, If that's the case have the radiator blowerfan motor replaced. If the fluid in radiator doesn't circulate then it meansthat you have a blown head gasket or a faulty water pump. I suggest that you gofor the water pump replacement first specially if you think that it's near theend of it's service life. Usually, water pops out the radiator when engine isreved (a sign of faulty water pump and possible blown head gasket). Hope you find this information helpful enough and thank youfor using FixYa! Have a good one!

I had the same problem with my 2000 Saturn LS2 and after replacing the fuel filter, fuel pump, ignition module, and coils I still had the same problem, I found out it was the crank sensor the whole time, after replacing the crank sensor the car is running fine and I spent all the money on the other parts for nothing. It didn't show up when put on the diagnostic machine, I am so glad that I finally found out what it was, hope this helps.

Maybe resetting the theft system. To do this you need to get in the car, turn everything off, turn the key to on, wait about 10mim or so till the light stops flashing, them turn key to off and back to start engine.

grinding noise was probably a bearing in ac compressor, when it froze up completely it stopped turning causing extreme wear on the belt ..so it broke... check ac compressor out , could be bearing only ..could be whole compressor ..have it fixed...when compressor is removed the hoses have to be disconnected of course so if it still has refrigerant in it, that will need to be recovered at a shop..the ac system will have to be vacuum pumped down and recharged anyway.

Saturn tail light housings are a known problem. Saturn had a service bulletin on them and would even compensate for the expense of the replacement for the 2000 model in late 2000 and 2001. The contacts are cheesey and made of plastic...get hot then warp and break. Poor design and a unreliable system. Cost on replacements is very high. You might find a useable one in a salvage yard, hard to say if it works until you install it.

You loosen the trans pan & remove some

that is usualy referred to as the B pillar

Barry-this is a known issue with Saturn transmissions, and it is the valve body-there is a little cottage industry for rebuilders (they run around $200) and are fairly easy to replace without removing the trans. Before you go into that, though, check the harness connector on top of the trans, this is also known as a weak point on Sattys-Trans services on these cars is very easy, it has a drain bolt like an engine and a spin-on filter too, and the trans should be serviced every 30,000 miles, use Dextron-Mercon. I had this problem with mine 99 SL2, and have been changing the trans fluid often (3x in the last 6000 miles) and it has fixed mine of the ,delayed reverse'. A side affect of this problem is the 'slam' you get going into reverse, or even forward gears, and that ends up needing to have the input shaft bolt replaced. $2700 for a trans is a joke, you could solve this for MUCH less, a number of different ways.

You need the a/c recharged. I believe they call the freon r16 now.

Check your fuses if they are fine your blower will have a resistor that you will need to replace.

Hello rperez423,

Below are step by step instruction and a picture for a Saturn LS with a 2.2 engine.

First thing to check on an injected engine with high idle is for intake vacuum leaks. Unmetered air entering the intake can cause high idle, as the o2 sensors add fuel to correct the mixture. The result of this is often a high idle. Spray carb cleaner around the intale and on vacuum hoses and connections. Don't forget the power brake booster, which is powered by engine vacuum. You don't mention engine size, however I've seen the rubber boots on the intake leak several times on the 3.0. Try not to do this carb cleaner test on an incredibly hot engine, and stay away from the exhaust. BE SAFE. Another method is to use propane to sniff out vacuum leaks. Either way, engine speed will either pick way up, or it will stuble badly when you find the leak, depending on location. Good luck!

Hello
I will see if the information is available. Give me some time to locate. Thanks

need to know what engine size and single or daul cam?

Does the brake pedal feel hard? It could be a bad brake booster.

The first thing you want to check is the transmission fluid level. In your vehicle it's pretty difficult as there is no dipstick for the transmission fluid, only a fill cap. The fill cap is located under the hood to the left of the fuse box and straight down. It will be a red cap. You might want to try to add a small amount of fluid, drive and see if it's better. If that doesn't work what you want to do is get that Service Wrench light scanned for codes. There are many ways you can get the code pulled for free at Free Check Engine Light Check After you find out what the code means, you are closer to finding a diagnosis. From my experience with these transmissions, you are most likely looking at a Transmission Pressure Control Solenoid.
