FIREMAN Posted May 24, 2010 Share Posted May 24, 2010 My AC 460 the other day started not spooling up and it would not accelerate for about 2 to 3 seconds and then it would take off. Once it gets to working it will work right going down the road. It seems to work better with the cruise on. Pull up to a stop sign or get behind slow traffic it will idle down and sometimes it will try to die unless you can get back on the throttle and pump it a time or two and then it may keep running. If you can keep it on the interstate it seems to work better I had it at the dealer the other day and they repinned the connector to the VGT ? and I couldn't make it mess up so I thought it was fixed but it wasn't When you are coasting along and mash down on the throttle it won't work but if you pump the throttle a couple of times it will then respond. Could it need the pedal calibration deal from Mack the 12B fix ??????? Can somebody help me Mackpro68 where are you? Quote Link to comment Share on other sites More sharing options...
