305 tpi idles fine then randomly dies ????
hey guys after changing all the temp sensors and fired up the car sometimes it has a hard time to stay running on its own so you keep it reved up a little it works great then you let it idle for a bit and it will stall while its in park and no one near the car then.... and when slowing down from 40-50 mph the rpm willl fluctuate up and down between 1200 and 2000 rpm??
please help with any thaughts im thinking it could be the tps but not sure

IDK exactly but it could be a vacuum issue,check the egr valve first.but mine started surgig like that then finally wouldnt start at all,come to find out one of my injectors is shorted out which is shorting the ground out on the inj circuit.I can unplug the one inj and itll start and run(rough) but it'll go straight dead when I plug that one injector in..maybe this helps maybe not but its my experiences...wish you well man
