Engine Performance problem
2002 Saturn SL2 4 cyl Two Wheel Drive Automatic 150000 miles
Car has been running relatively well until early this week. Initially it wouldn't start when the key was turned. It would chug and sputter a few times, but it wouldn't fully turn over. I gave it some gas, and once it was running continued to run. I've done that on two or three more occasions since then with no change in symptoms. It makes no difference if the car is warm or cold. It's idling around 700-800 rpm (give or take, doing this from memory).
The car MAY be a bit rough at idle from time to time, but it could be a bit of paranoia on my part. Shifting can be a bit rough when the car is cold, and that loosens up some as the transmission warms up. On the day before this started, I was parking the car. I shifted into reverse to get the car into position, it hesitated a bit longer than usual, then a surprisingly huge CLUNK before it shifted into reverse. I put it in drive and moved forward, then back into reverse to make sure my transmission was sitting in pieces ahead of me, but it shifted normally after that.
The throttle body has the amount of deposits one would expect with 150k miles, so I picked up some TB cleaner (haven't used it yet). The last year or so the car has been eating a fair amount of oil (2+ quarts between 3k+ oil changes), but I'd like it to last at least through this winter.
I'm leaning towards the MAP sensor ($50), and considering the low cost of an ECTS ($9), I'm considering swapping that out, as well.
have the same problem?
