help?
ok so i kinda just joined here but i've been an enthusiast for a while.
I have a 2001 volvo s40 1.9t its nice i love it but theres a problem for some reason everytime i floor it black smoke comes from under my car. (or thats what friends say) my check engine light starts to blink at around 4000 rpms. also when its at around 4000 rpms the car shakes like theres something wrong with the turbo. its like when the turbo spools faster it just starts to jerk. i dont know if anybody has had these kind of problems before does anybody have any ideas? :confused: |
Check the spark plugs,coils and wires.

check the engine mounts as well...

more than likely you need a thorough tune up!
|
The black smoke is un-burned fuel...
So you need more air/spark. Like above, a tune up is a great start! |

I'm gonna bet misfire.
based on the fact that the CEL blinks at WOT -- very common sign of misfire I believe (do you concur tech) everything I have read about misfires say that. check plugs, coil packs for cracks/wear, and plug wires Good Luck! |
