1998 Grand Prix problems
I have a 1998 Grand Prix with the 3.8 sc. It
seems fine sometimes, but it will
intermittently stall even while driving. There
is no light to check. It will start up strong
sometimes and others it won't. Also, there is
some top engine noise rattling. I am not
having acceleration issues either per se, so I
don't think it's the crankshaft position
sensor. It has a smaller pulley on it because
the previous owner wanted to speed it up,
but that has been on there for years and the
problem just started recently.
Update: it has a low coolant light on even after I've flushed and filled it. The ABS light is also on and I can't turn TCS on, but the light is on.
The low coolant light is on due to the coolant level sensor is more than likely fault and needs to be changed. The coolant level sensor is located below the radiator cap and is usually grey in color.
You must remove the support bracket and the battery to get to it and you will lose a little radiator fluid.When you get access to the sensor remove the wire around the unit by pulling it upwards and after the pin is removed pull the sensor out towards the motor. You must wiggle it to remove it. Insert the unit in the same way and reconnect the unit.
You can go to a tire place like midas or others and they should be able to reset it. Or, you can remove the battery for more than a half an hour and the computer will reset,.
Wheel bearing likely is bad or wire to it, tc is disabled by this sensor. Clean the throttle plate by removing the TB, you'll have a little coolant leak out and a gasket to replace but it gets really gummed up and closes off air let engine breath at idle. Only use tb cleaner and don't spray maf. Remove it if you have safety torx bits. Engine noise is common, lifter ticking, not a big deal unless it gets louder. Others answered your coolant light deal. Good luck to ya.
What would be the problem if my car only goes 5 mp..im strapped 4 cash and trying to resolve the problem
