#154 of 237 1994 Saturn SC idling
Mar 09, 2009 (7:06 pm)
I've owned a lot of cars, but never a Saturn. We ran across one that looks like it's right off the showroom floor, runs like a top. The only thing is it is idling at about 1100 and is normal when moving. I looked this up and it said to set to 450-650 and I found 4 things that could cause this. Would you recommend just resetting the idle speed or what?

If you still have car make sure you install the engine coolant temp sensor with the
Saturn upgrade and cable harness.I installed a $10.00 autozone ECTS and it didn't work right.When the upgraded one installed (get it at Saturn) my problems were solved,rough start and high idle,alot of smoke coming from exhuast.
#156 of 237 Spark Plug choice
Mar 29, 2009 (8:01 pm)
About a year ago I purchased a used 96 SL sedan with SOHC engine and 5 speed. Did some basic maintenance, coolant flush, new plugs (Bosch Platinum 4s) and wires, new tires, muffler, and minor TLC. For most part, LOVE the car and drive it enthusiastically (i.e. don't follow the upshift light, rev above there regularly). When I took the car to a mechanic for a tuneup (after my work and repairing two minor exhaust issue/leaks), I was surprised when the mechanic told me the Bosch plugs were TOO HOT for the engine, and he, without my approval, replaced the new Bosch 4s with OEM type plugs (ACDelco, may be single electrode platinum) then tuned it.
From some research I did prior to purchasing the Bosch plugs (and after consulting coworkers/mechanics at the local auto center where I work PT), I can see where the Bosch plug may burn somewhat hotter than an OEM, simply because it produces a more uniform burn "kernel" at ignition, thus being more efficient and producing more power (and heat) for the same amount of fuel. I understand that the heat range of a plug is important to the overall performance and longevity of an engine. Was I wrong to assume that the Bosch plug specified for my vehicle would be the same heat range as the OEM plug? If "yes", why would Bosch do so if it may damage the engine parts, in the long run? Should I switch back to the Bosch 4s, or something in between the OEM and the 4s, say Bosch Platinum 2s?
Sorry for being long-winded.
BTW, I'm new to this forum and really appreciate the depth of knowledge here. I'm a shadetree mechanic and appreciate my car for the relative simplicity of many repair tasks. Will be replacing the primary O2 sensor tomorrow as I, just today, had my car send me the P0133 code.
Thanks again for all of the wisdom this board contains!

Hey all, my SL1 has ~87,000 miles and is starting to make a lot of noise. No check engine light, doesn't seem to burn oil, drivability is the same as always. By the sounds of it I may have a similar problem to lilbirdy and elyons on page 5, but there wasn't an apparent resolution posted here.
So the sound kicks in around 20mph and maxes out around 50mph, and gets a little less noticeable at higher speeds (or maybe just the usual sound of rushing air at highway speeds drowns it out.) It's completely uncorrelated to how high the revs are, what gear it's in, turning corners, etc. As elyons said it seems to be coming from just on the other side of the dash, a little bit on the driver's side of the vehicle. I would describe it as somewhat similar to the regular engine sound but louder, and with a rougher vibrating sound to it. I changed my spark plugs a couple months back just as regular maintenance; the sound wasn't apparent at the time. Another thing I've noticed lately is improved fuel economy. I commute on the highway and monitor my gas mileage closely, always have been around 42mpg but lately it's been closer to 47mpg! That's great and all but I'm wondering if it's running too lean? Another habit I've had in trying to get great mileage is putting it in neutral on long, downhill stretches on the highway. Is there any way that could be impacting this?
Another thing I'm not clear on, will a scanner produce any codes if the check engine light isn't on? Any input would be much appreciated, I've already learned a lot from all the previous discussion.

I just changed a clutch on a 96 sl-1. After putting engine and tranny back in, I have 2 connections that I cannot find where they belong. 1 connection has a grn/wht and a pnk wire and the other has ppl and yel. Engine turns over, just won't fire. Any help would be greatly appreciated.

Hi, billja. I have a similar problem on my '96 SL-1. Over a year ago, I replaced the thermostat, flushed the cooling system and also did the Temperature sensor while I was at it. And yes, I got one from Autozone cheap. Almost immediately I had issues. The temp gauge went up to the halfway mark as soon as I started it, and the electric fan also started as well. The fan has only come on when I use the A/C in the summer, so I thought this was odd. I thought it was a fluke and let it go a few days. It was NO FLUKE! Good thing I kept the old sensor, and I put it back in and had no trouble for a long time till recently. One day about a month ago, I started the car(in cold weather here in Pa)and on came the fan. Now the car heated up quickly as it usually does, but the temp gauge barely moved. I got out and put my finger on the 2 wire connector on the sending unit, and the fan went off immediately and the gauge went up to its normal position and I had no problems. Now today, after it sat for about 4 days, the same thing is happening, and the cooling fan wants to run again! I have a feeling I have a bad connector issue here, not so much a sensor. I remember I had trouble getting that plastic thing off the sensor, and it did come off hard last year. I called my local Saturn dealer and it seemed to me that he knew there was an issue with these connectors and they have them in stock for about $25. I will probably go pick one up, but I'm wondering if I should get a new sensor while I'm at it. I wonder if the one for the '96 and '97 are different? What does ECTS stand for? Is it Electronically controlled Temperature Sensor? I may not get around to do this until spring!!

I had a similar EGR issue with my '96 SL-1 over a year ago. I didn't have an OBD2 scanner then(I do now) and the engine light kept coming on. My former boss at the time used to buy Saturns and fix them up and sell them. He said they were great cars. I've had mine for nearly 3 years now. He read the code at the time and it was an EGR problem, and he said he just might have a couple of them in his garage at home. He still had a large number of parts, he told me. So he brought 2 of them in and I took them home and the next day put one in, using a new gasket, then we cleared the code. All was well for a couple of days, then the same code again. Put the second one in and maybe a week later, the same thing. So BOTH of the used ones were duds. Autozone wanted $150 for a new one, and Saturn was even higher than that. So I got one from a salvage yard not very far from me. This yard specializes in Saturns. For 40 bucks, I got one that was so clean it looked like it came from an auto parts shelf. Been in ever since, and I have had no recurring issues with it. Just thought I'd share this with you. Happy New Year to all!
#162 of 237 Coolant Temperature sensor issue-Update
Jan 06, 2010 (12:32 pm)
Hi, everyone, I just wanted to post an update on the problem I was having(see above) regarding what I thought was a faulty coolant temp sensor. Today, as cold as it is here, I set out to get to the bottom of the issue. I went to NAPA and bought a new sensor, but on the way home I decided to stop at my local salvage yard and see if I could get another 2 wire connector there instead of having to get one from the dealer. I got lucky and they had one. Came home, replaced the sensor, but put the OLD connector on and started the engine. SAME THING HAPPENED- on came the fan, and my temp gauge went right to halfway! So, in my case, the problem was definately with the connector. I cut off the original one and spliced in the one from the salvage yard, and I am fine!! The car started up with no fan on, came up to temp nicely and all seems well. Probably didn't need the new sensor, but I gambled and it was only $11.50. If any of you have this issue in the future, you may want to replace the connector first and go from there.
#163 of 237 Applique Part number 21170740
Feb 15, 2010 (1:35 pm)
I want to replace the Applique on doors of our Saturn SE. The paint is worn off and makes the car look older. The part is on the exterior of the passenger door and dirivers side door (entry side) I have the replacement parts so the part should come off. Do I have to remove the entire door. I can send a pic if needed..The dealership was no help. I have asked this question to the Edmunds experts iand the question is still open.
