High rpm issue
Ok I got stranded one day just stalled out so I scanned it came up with throttle body and pedal codes so I replaced the tb and app now when I start it the idle races to about 2500 to 4 grand then after a minute ot drops then stalls out then also threw a mad and map code I checled wiring I got the 5 v ref and grounds and power to the map amd maf also check resistence in the plugs so im almost certain I ruled out electrical so I'm not sure where to aim next any ideas guys not aure if I ahould check vacuum for the high idle or pm issues whatcha guys think?
