[tp550i]

update: 8 new injectors and spark plugs later, the car feels "new" again, smooth idle and power - Big improvement.

after reading all the posts dealing with bad injectors on the 550's I've been waiting to see if I would have the same problem. this is the first replacement

I only have 24k miles, 2 weeks ago it was CEL with bad O2 sensor, then CEL this week all 8 injectors are being replaced with the "newer" injectors.

this is frustrating especially after last years FP issues on a $65k car.
