Hi Everyone, I've been searching for an answer to my problem all morning and have come up short with an answer, hoping someone may be able to help. I have a Xr6 turbo bf and was driving it a little rough, turned onto the highway and hit the accelerator (didn't plant it)... As soon as I was between 3000-4500 rev suddenly my engine started to shudder and I had a complete loss of power (revs dropped down), the car is still driving alright and the engine isn't shuddering now but the "check engine light" came on (but turned off a few hours later). It's happened a few times when I try and give it some, has anyone else had the same problem or does it have something to do with the rev limiter? ANY HELP WOULD BE APPRECIATED AS I AM A NOOB!!
