When the car reaches a speed of 70 mph the acceleration dies. Car can travel at speeds less than 60 but once is goes past 70 mph the car sputters and the check engine light comes on, the acceleration dies and the car slows down till it stops. I turn the car off for 10 minutes then restart and I can move again but the acceleration takes a while to get up to even 50. After the car rests for hours the car acceleration returns to normal the engine light goes off but will only stay normal if I stay under 60 mph.. Im sure its fuel pump issues but please help...
Run the fault codes first to check for faulty sensors
what you describe indicates a problem in the exhaust in that when the exhaust gas volume reaches a certain level the sensors are reporting it and the ECM is not able to fix it
have an accredited exhaust shop check the cat converter
for failure and partially blocking the exhaust at speed
if it was a fuel pump you would run into problems long before the speed at which it occurs
AT best it could be an EVAP problem with the vent not working properly but I think that it is exhaust related

Saturn says and I quote
there transmission fluid is not to be changed after the first change at 6000 miles.
Now I say it should be changed at every 30000 miles. If changing out the fluid doesn't work then you need to go to a transmission repair shop.

first problem, went to autozone. the guy that looked at your car was making pizzas last week. they pull codes and sell you every part you will buy. take the car to the saturn dealer and replace the bcm.
SOURCE: will not start after it stalls untill about 5-10 minutes
Your problem is most likey your intake gasket.They have a problems on the SOHC engines where the intake gasket shifts & starts leaking vacuum at the #1 intake runner causing a missfire on Cylinder #1.While the engine is Idling buy some throttle plate cleaner & spray throttle cleaner down at the #1 Intake runner where the intake meets the head.If engine stalls or runs rougher that's your problem.I have replaced dozens of those gaskets for tha reason!! They have a beter design gasket through saturn parts.It has a coating on it to prevent reoccurance.Also you should check you Coolant Temp Sensor,if it's ceramic it's most likely bad.Replacement is brass from saturn.Good Luck

Disconnect the vacumm line to the EGR valve and plug the hose. If this solves the problem then your valve is bad.
