Better thing to do would be to post your problem and symptoms here. We can
help, there is no point in replacing parts that don't need to be replaced.
Is your check engine light on? Did you scan the computer for DTCs?
Also remember to always post year/make/model/engine/mileage with posts.
I did do that on the 30th of September, but did not get a single reply.
BTW the service light comes on intermittently. Here's my post from the
****I have a 96 Saturn SL-1 (5 speed). I had a tune-up done in
July........plugs, wires, filters, new fuel pump. It's been running real
crappy for the last couple of weeks. Idle is racing up to 2000 rmp and as
high as 2800, and it's been jerky when taking off and sometimes when you are
just putting along, almost like a hiccup. A real pain. So I take it in and
they find a vacuum hose that was wore right through. He figured that would
be it. And of course when he took it for a ride after, it didn't act up.
Well it still is. Any suggestions as to what it could be? A friend
suggested that it might be a coil pack. I'd like to hear from any other
Saturn owners or anyone in the know about what my car is doing. BTW, they
checked the work that they had done in July, and the plugs were not fouled.
Also........wait for it........there are 345,000 kms on it. Thanks to all
responders in advance as I'll be away from my computer till Monday. have a
Ya, I remember replying to this one:
"First thing I would do is stick a vacuum guage on it and see what it's
doing. That will tell you alot."
Also check you timing....
Did you do that?
the throttle position sensor for your car is about $35 at kragen. it
like it is the problem by the symptoms you describe. if
you have a voltmeter,
you can test it. there are 3 wires on it, one
is a +5v wire, one is a ground
wire, & the last one is the signal
wire. take your meter, turn the key to the
run position but do not
start the car. pull the plug from the TPS and determine
are the +5v and ground. with the plug unplugged from the TPS, the
3rd wire should give you no reading, or nearly no reading. reattach
the plug &
now stick your + meter probe thru the insulation on
the wire that you determined
is the 3rd wire or signal wire, and the
- meter probe to you guessed it, the
ground. while watching the
meter, slowly rotate the throttle open all the way.
should change slowly & evenly without suddenly spiking to 5 or
zero anywhere thru the motion. if voltage jumps wildly at any
time or doesn't
change at all, the TPS is bad. this test is best
performed with an analog
voltmeter (needle type) but can be done
with a digital one.
