A light stall before acceleration...Help
So today on the way to a meeting, I decided to open her up a bit. Going about 50mph, I dropped it to 2nd and it seemed like the car stuttered for a second before taking off. Same thing with 3rd. I slowed down and tried again, and same thing. It's not like the feeling of turbo lag. Literally felt like nothing happened then engaged and took off. So I drove it regular for a bit and tried again, and then it was fine. Just regular turbo lag. Then again, the stutter happened again. It's happening on random occasions. Anyone experience this or what's happening? Knowing the n54, something is failing. Looking to be proactive.
Car is Stock except ppk 2. Just did an oil change last weekend and replaced T stat.

sounds like a misfire. I would start with changing all the plugs.

dying coil pack/plug is where i'd start. get a code reader (just go to autozone and ask someone to read codes) to figure out the cylinder then swap a coil pack with another cylinder and read codes again to see if it goes to another cylinder. if it does its the coil.. if not try again with the spark plug.
there are a million other things that could be going on, but i'd start with those. once yu get the code reading it should be easier to pinpoint your issue. |

I was experiencing hesitation during hard acceleration, exactly like you described. On the freeway, dropping a gear or two and accelerating at mild to hard acceleration, I felt hesitation - like the traction control cutting in.
No engine lights, no error codes. Turned out to be carbon buildup on the intake valves. Had the valves cleaned and the problem went away. Car now accelerates smoothly. Car had 53K miles at the time. You should look into this. |
