Hey guys I'm new here just got my VR4 this weeks. I bought it with a slight idle surge goes from 800-1000 then 600. The guy i bought it from said it was because of the after market cams. I instantly checked for a vaccum leak but didn't find any lose hoses etc. I'm coming from turbo charged K-series hondas but haven't played with them since 07. I unplugged the TPS and it idles perfect. In addition if I'm on it and I let off the throttle too soon it'll die sometimes. I'm just trying to look for a general area to start or even if i have to get it tuned find a place around north Chicago that isn't trash. This is the list of mods from his add.
