I installed my plenum and t/b last night, but didnt take it out until this morning. When I turned it on I realized that the idle was jumping a little and not very smooth. I figured this was normal and would go away by tomorrow after I drive it a little. Well today its only gotten worse and I cant seem to fingure out why. Ive checked all my valves to make sure they were tight along with my botls. Do I need to do anything to my idler valve? If so which one is that and what do I need to do. I also disconected the battery to reset the computer but that didnt seem to help. I have the superchip microtuner which I changed the octane to 93 instead of the stock 87. Ive been running 93 for awhile with the chip and havent had any problems. I dont know if changing the octane affected the timing. Could the octane or timing have any effect on my idle. The idle is so bad that my engine shakes and causes the whole car to shake. Maybe my air/fuel ratio is off and im running lean? I havent gotten on it at all really since the install, I just brought it up to 4-5k and can feel a difference. Can anyone help me?
