1994 Saturn SL1 My Saturn sputters, exhaust sucks slightly, n

I know this seems like a strange question but what position does the cooling fan turn on the temp gauge?

You have to think also do you have a enough fuel pressure?So the injector get's your engine the correct amount of fuel. Do you have any code's also what mark on the gauge does your cooling fan turn on?

You can rent a fuel pressure gauge at auto zone to see what your pressure is.There is a cap on the threaded port you screw the hose from the pressure gauge to that then start the car and see what the pressure is.The port is on the line going up to your throttle body.I would also see if your fuel filter is clogged or restricted.You could also have a plugged cat.Have you replaced your coolant temp sensor yet?Also inspect the connector to the coolant temp sensor if it's corroded then replace the connector too.There only 10 make sure you get a brass tipped one the plastic tipped one's crack.It's the bottom sensor with two wire's going to it make sure the engine is cold and you will loose coolant.
