Rough idle, white smoke, BAD Smell
My car has been running fine....It's a 2000 S70 GLT with 71,000 miles. Last night, my wife drove the car and complained that it was running poorly. This morning, I fired it up and have the following issues:
1. Rough Idle, takes longer to start up.
2. puffing white exhaust
3. the smell almost reminds me of Gunk engine degreaser coming out of the tailpipe...
Oil looks good, coolant level is full. I don't have any bubbling in the coolant reservoir at idle. CEL is now lit. She had to drive it about 15 miles last night and the coolant temp. was normal the whole time.
Do I have a bad turbo?
Thanks for your help,
Drew

RE: Rough idle, white smoke, BAD Smell
Thanks Tech,
I drove it carefully to Autozone, car has no power.
They pulled a P0300
The PCM has determined that multiple random misfires have occurred
1. Ignition system fault
2. Vacuum Leak
3. Injector Fault
4. High or Low fuel pressure
How bad is it? Where do I begin? Does this rule out the headgasket or turbo? The coolant and oil look fine to me.
I now realize the smell is unburnt fuel.
Your help is much appreciated,
Drew

So typically, your recommendation would be to replace all the coils and plugs?
I'm pretty sure the car hasn't had a tune-up. I received a notice in the mail from the dealer saying it was ready....what's all involved? They treat me pretty
right price wise...should I just take it there and have them do the complete tune up?
Thanks again for your advice,
Drew

RE: Rough idle, white smoke, BAD Smell
....But before I do...just to be clear, I replaced just the one coil pack on the plug that was severely fouled. I was reading another thread in which you said to inspect for hairline cracks.
I noticed that all 5 coil packs have a hairline crack. A couple have 2 or 3 cracks. Could this be it? What confuses me is my car was running fine, then it was started up three hours later and would hardly run at all.
Also, during a local search for the coil packs, one dealer asked why I wanted all five. He said that he has never replaced all five at once and he thinks I'm crazy for trying it.
I trust your judgement as many people on the board here do (especially since you're diagnosing online...not easy) If this ends up not being the issue, where do I go from here?
Thanks,
Drew

What causes this? This car is like new.....and I'm not beating it when I drive it. I just limped it to the dealer....I noticed when I came home that I have a spot of oil on the floor.....DAMN!
I feel like getting rid of it as soon as it's fixed!!!!!!
