So i came home from work, turn on my car and crap... my car works like a tractor, feels like one cylinder doesn't work. Car is shaky and doesn't accelerate.Engine light is on. I have RD cold intake, so i took it off. Same thing. It's a new car it has 17 k miles on it.
What should this be, and should i drive it to a dealer like this or get

I just talked to a friend mechanic and he told me it could be a Cam shaft position sensor failure

Dealer replaced Coils and spark plugs. Isn’t it too soon to change all that. I have only 17,000 miles on a car.
Could Cold intake cause this problem?

Looks like you're doing fine having a conversation on your own :P

What kind of car is it? Attributes?

Not much anyone here can do with the info you gave...

Ha someone is here
Well it's a 2003 325i. I am so mad since i got this car i had problems.
I just wonder if RD cold intake could cause coils to go bad. I am not putting CAI back.

coils can go bad. plugs not likely.

unless you sucked up water into the engine, it ain't cold air.

I had a similar problem with my car about a moth ago. The car was sluggish and the steptronic started in emergency mode like something had happened. I took it in and the Mech told me that the battery had a bad cell and that they had replaced it . When the car was cranked with the bad battery it was not getting enough power and the ECM put the car in basically energy saver mode. I do not know if this will help but a battery is a lot cheaper than full blown engine work.

Time to sell it and buy M3 .
After 5000 miles transmission was changed, went to a dealer for small things at least 20 times, now coils went bad. Crap. I have no luck with this car

Dinan is the only way to go for those types of upgrades, they test every config and that's why they are the only BMW authorized custom.

With Dinan if you upgrade to a free-flow cold intake they require a 'software' upgrade to your engine. I'm assuming you didn't change any of the software and you are having issues based on that.
