Car feels different after this

AltecBX · 12-16-2010, 04:45 PM

This car feels much more responsive after I got this done. It feels like I have a v8 under the hood on the freeway. Also, the car just goes when I tap the pedal. Dealer replaced all 6 spark plugs and injectors. I also got an oil change with new filter. For anyone who is misfiring or car is feeling sluggish, DO THIS.

What do you mean "choking" in the statement? Does your car violently shake after a misfire?

AltecBX · 12-16-2010, 04:55 PM

That's how my advisor worded it..

Same thing happened to me. But I got a new DME and the waste gate retrofit option programmed. Honestly, the car feels a lot faster on the lower end, as soon as 1500 rpm. I know it was not like this before. It just falls flat on mid RPM since it's stock boost.

which dealership did you go for this ?

Bimmer This · 12-16-2010, 05:41 PM

I heard that there is a bulletin out there for bad injectors.

AltecBX I just picked up my car 1 hours ago and look. I did the same thing.

I will agree with you a millions times. I did notice a big big change. I hope it stays like this for a long long time. But they should have just did the coils too

To think I have been driving around like this for the past 10000 miles. Sad Sad Sad.

Very nice. Congrats on the job getting done.

Yea, I can't believe my car felt so under powered before. This is a must do for anyone that hasn't done it in the past few months. Car really feels like its' another car.

Taking mine in tomorrow for the same thing. Hopefully they replace both injectors and plugs.
