The car run but it wont idle , i had a p1129,p1128,p0132,p0152, but I had a VAC hose off, Erik told me it was the o2 sensors , because the VAC hose was off, but we put it on, but it won't stay at an idle, throttle pos, at 5% it will run, and no codes. Any ideas ? hemie31 told me it might be an push rod, but I'm not getting any cods or miss fires. if the heads are milled, do i have to get a new tune, in just going crazy right now:help::help
