double exposure
Guest
Hi guys! Hope i can get some help here, lateley i have been expriencing engine struggles/roughness after 3000 rpm. It is a 1999 jdm spec R, it boosts fine (1 bar) but is undrivable after the 3000 pm rev range. It feels like its not sparking or something but just a huge loss in power and real jerky and rough with smoke coughing out the exhaust. Below 3000 rpm it is quite fine and drives smoothly with the occasional rough idle. Just wanted to get othere peoples thoughts before investing money to this issue.
Thanks.
Thanks.
