What’s up man, you seem to be the victim of the saturn idle. The most
annoying thing~! Mine is doing something similar but not quite. Anyways I
think your problem is eazier to handle. I believe its your idle control air
valve that is attatched to your throttle body. It’s like 40 bucks at a
local shop and you can change it yourself. It didnt work for me but like I
said I have a different problem. Let me know if you need more direction,
I’ll help if I can.
My 99 SL2 automatic has done the same thing for almost 200,000 miles. I
guess Ive just been used to it all this time. In fact, the performance
hasnt degraded at all over the life of this car as far as I can tell. Its a
great car that still begs to run flat-out (117mph) daily!
Most modern cars with manual transmissions will hold the idle a bit higher
when coasting and shifting gears. My 99 SL2 holds it at about 1200 to 1500
when warm, and about 2000 when cold. Check your temperature gauge.
what temp sensor isent there 2 one by the fan another by the coolent. and
was urs doing the same exact thing shown in the clip or slightly different
cause mine was the same exact thing
It Is The EGR valve. I know you said you replaced it. Cleaning it doesn’t
cut it. And you got to get a good one too. $124 for AcDelco. Small price to
pay to get another 140,000. I tryed cleaning mine too, sometimes it seem to
help. But when I finally replaced it with a NEW egr valve, this problem
went away and hasn’t been back going on 5 years now.
If the TPS % doesn’t drop back to 0 (on analyzer), this will hold your idle
high. Computer thinks that throttle is still open, and adjusts timing
accordingly. I replaced my TPS after I couldn’t get it to work right
anymore, and now the idle drops back to 950-1000 every time I disengage the
clutch. On a side note, gas hit a peak of $4/gallon when Bush was president.
1. Clean the throttle plate and intake manifold with Cleens u get it at ur
GM dealer. 2. Get ur IAC, MAP and TPS checked make sure there in there
operating ranges. 3. See if ur intake is cracked and listen for vacuum
leaks.
I have to agree with you. This is just a Saturn sl1 and sl2 thing. I love
this car have almost 250 000 k on it and it runs great! Once the coolant
hits the right temp everything is fine. Have to just live with it.
If it doesn’t get past the 1/4 mark, then your thermostat is bad.
Unfortunately Saturn made a thermostat with a rubber edge on the little
door that opens and closes, and this goes bad, preventing the thermostat
from closing fully. With this problem the engine won’t reach operating
temperature, which is about 1/16” past the 1/4 temp mark. If the needle
only gets to the 1/4 mark, your standing idle will be above 900, and coast
will be at 2000. Standing idle should be 900 or 850.
i seriously having the same problems but mines an automatic it kept running
at 3k rpms the whole way to work when in neutral but if i keep it in drive
its like on cruise control no gas and i’m going 40mph but then again just
like how its showing in your clip it goes away idk why you did a ton of
stuff just wondering what you think did the trick. while trying to avoid
spending a ton of cash on this. ever do the tps? some co workers and family
think its that but its 40 bucks and if it won’t work..
Dude It’s the EGR valve. I had to keep cleaning mine too, but once I put a
NEW one on. That problem went away, and it hasn’t been back in 3 years now.
I know they cost alot, but I’m telling you. It’s EGR valve.
Thanks toyandfrank. I did replace that. Here is a quick list: Coolant Temp
thermistor IAS Throttle Position Sensor PCV Valve Tubing connected to the
Evap Purge Valve Cleaned throttle body As you saw, it fixed itself but… A
few days later it started doing it again. so… I did some testing on the
fat vacuum lint from the manifold to the PCV valve and who would have thunk
it, the rubber elbows were dry rotted and porous. Wouldn’t hold a vacuum at
all.
my 93 saturn wont start inles i use starting fluid and it only idels with
my foot on the gas i changed the idle sensor and the idel position sensor
still wont idle do you have an idea?
I have the same problem with my 1995 saturn sl2 automatic it does that itll
go up to 2500 rpm when i start it then bout 1 min later it comes back down
to 1k
){kind=link}
what is the trouble code
you might have a bad intake manifold gasket or throtle body gasket because
basically some where more air is leaking into the system
had same problem it’s the egr valve
throttle positioning sensor
Try fuses or sensors it doesnt seem like a big problem
Dude…Dave you the man…THE MAN!! you fixed mine tytytytyty your nickname
is rich pinn jr hahah

check the iac valve idle air control valve or a vac leak on the throttle
body
1. Clean the throttle plate and intake manifold with Cleens u get it at ur
GM dealer. 2. Get ur IAC, MAP and TPS checked make sure there in there
operating ranges. 3. See if ur intake is cracked and listen for vacuum
leaks.
If your temperature gage does not rise its the problem

lots of saturns have this typical problem my saturn even had this problem
at once and a bracket or clamp was loose
check your fuel pump, or fuel filter.
