R53 Most liked posts in thread: First car with a weird past

it's limiting me just right before 5k rpm for some reason, i can't name why or how, I heard that bad valve train can cause something like this, but I can't tell if it's a fuel cut limit or the car just not wanting to go.

 

how would i check the timing chain?

 

i mean oem injectors not the upgraded ones, im pretty sure my current ones work just fine so im probably not going to do it.

 

The lil' car is fixed! turns out it was the ignition wires, but over the course of this whole thread I've just made the car so much better than it started out. I'm not even mad about, "wasting" time and money with other parts of the car. My crank pulley was on the way out a bit ago, after a hard drive it would smell like burnt rubber, but now I have an ATI pulley. I fixed the choppy idle because somehow injector one was unplugged :/ and now everything is back to normal! Right now I'm really happy with the car! And I might start autocrossing, there's a local club here.
