Car probs in high RPM's. Please Help
Alright, so I took car to subaru to have CEL serviced, nothing bad. took wrx home, few days later, my car doesn't want to go above 5500 RPM's, it "chokes'' out. It doesn't want to go above it. It'll just sputter loudly. I talked to another suby guy here in town, he said it is my knock sensor....is he right? if so, how do i fix it? if not, what is it? he said it happened to him right before his cat's went and destroyed his turbo from the up pipe. Soooooooo please help. even if i do have to replace the up pipe , which i plan to, would that cause it? IM me at hartk20vtec or reply in here. thanks all for you help in advance.
