Question about 2007 Mazda B4000
I have a 1994 b4000 4wd manual trans. Just bought it as my commuter. Problem I'm having is that when I press the throttle WOT engine is not responsive and when moving the engine surges slightly. It does respond to part throtle opening can not pass hign idle test on scanner getting code 538 and 412. Just did plugs, wires, oil, filters, egr operating, and test out of tps is ok? Can someone help me this is my first mazda/ford v-6.
SOUNDS LIKE THE T.P.S. IS NOT FUNCTIONING. ALTHOUGH IT MAY TEST OK, IF IT IS NOT RESPONDING, THEN IT MUST BE REPLACED. UNLESS YOU HAVE A FUSE FOR THE TPS, THEN IT MUST BE THE ONLY REASON FOR NO THROTTLE RESPONSE. HOPE THIS HELPS. PLEASE KEEP ME POSTED. THANKS FOR USING FIX-YA. AND FOR AN HONEST RATING IN ADVANCE. GOOD LUCK.
