hi im new to this site and find it very good. i do need some help with my skyline and hopefully someone can help me. i have a skyline gts rb20de non turbo, its been converted to manual gearbox, and thats all thats been changed on it. the problem is the idling is quite random for example..when i first start it idles good on about 800rpm, after driving around town i stop at the lights, idle goes to 2000rpm plus. another thing is, when i lift my foot off the excellerator, as i change from 1st to 2nd, the revs dont come down in between changes. any help would be much appreciated, thanks for your time. im unsure how to reset ecu.
