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.
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!
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.
1997 saturn wont start when a/c fan and a/c buttons are on position can start first time in morning a/c can be left on position and fan can be left on . but once the car is running for a while with a/c on can not restart car unless i shut a/c down and turn fan off help. i was told it needed a fuel pump,fuel filter, alternator(generator) etc.etc. its just a pain to have to shut fan and ac off before i can start it or not use the /ac in florida noway.
thanks

i was told saturn s series has 4 different trannies, i think mine is DOHC dual overhead cam, how hard are these to repair> Or can i just drive it and make sure i keep tranny fluid in it, and forget reparing it? I like this car and wanted to keep it for a few years.
