2002 Saturn SL2 Needs gas pedal to start, runs fine after

I also wanted to add.

The engine seems to get to temp in the normal amount of time, about 3/8ths on the temp gauge, so maybe replacing the ECTS is irrelevant. When I first tried to start the car, after cranking several times for several seconds, and then giving it some gas, there was a small cloud of white smoke. I have not checked to see if that cloud appears every time, but if it does, it's obviously not big enough for me to notice from inside the car (I don't see a cloud in the rearview mirror).

I'm told the ECTS was changed to brass by the late 90's, so my 2002 has the brass version.

Will the engine have any issues pumping the thicker 10W, especially during the colder winter months here in Maryland? I've considered it in the past, but the manual pushes 5W.

On a side note, my gas mileage up to this point has been surprisingly good. I average 34-36mpg, with that being 80-85% highway.

It's still raining here due to the hurricane that blew in a ton of bad weather, so I won't get to touch the car until tomorrow at the earliest, possibly not until Sunday when the weather gets up to the high-60's (I can't work in cold weather, fingers cramp up). The more I know and the faster I can crank everything out in one shot, the better off I'll be.

Woo hoo! Success! :Banana:

I decided to tackle the TB since it's so easy. Opened it up and what did I see? Practically a pristine inlet! Other than a small smear of carbon on one edge, it looks like it was wiped out during my last visit to the Lube Shop. Makes me wonder why they're always trying to push a full air system cleaning "because of all of the carbon build up in your TB".

Okay, on to the plugs. Ooh, those don't look so hot. On second thought, they look [u:3b60758d87]really[/u:3b60758d87] hot, as in white crust all over. Man, that engine must have been cookin', probably what led to so much oil burn over the years. Spec'd for 0.040, the [u:3b60758d87]best[/u:3b60758d87] gap was 0.050 and the worst was 0.080. So, threw in some new plugs, gapped correctly, and crossed my fingers.

Car didn't even hesitate to turn over. Vroom! Started right up, sounded smooth and clean. We'll see if mpg goes up (or if it slows down on the oil burn), but it was already averaging 34-36, so I would be surprised.

I looked over the service records my SO kept for it (before I met her). The stealership was charging her to clean the fuel system, air system, etc. Every 10k miles! Spark plugs were changed at 30k mile intervals, right up until she stopped going to the stealership. About 90k miles. So, those plugs were in there for 90k. No wonder they looked worn out.

I'll switch to 10W30 on my next change, and I'll pick up a new PCV valve next time I'm near the auto store. When you say "sticky rings", what do you mean? Are the rings not sealing against the bore because they've somehow contracted and stuck that way?

I misspoke earlier. Saturn switched to the brass ECTS in 2001, not the late 90's. Either way, I'm good.

I'll have to dig through the records again to see when the tranny fluid was changed, but I seem to recall it being done last year. A bit of research tells me the tranny clunk in reverse is a very common problem with Saturns (Google "Saturn reverse slam"). The suggested solution, in a nutshell, is to change filter/fluid, add in some detergent additive, chock the wheels, and leave the car idling in reverse for 20-30 minutes. This supposedly breaks up the grime in the reverse and 2nd gears (which share a common path in the valve body), both of which I've noticed harder than normal shifts. If this is done before irreparable harm has already happened to the valve body, you're good to go. I may give it a go.

At least the car runs now.
