...miles an hour? but when I let the revs drop below 2000 rpm the engine light comes on and it goes into limp mode and then will eventually cut out. The engine will restart immediately then rev over 3k rpm no problem but blow out black smoke. The truck has now been in 2 different garages for a total of 6 weeks. The first one replaced the 3rd injector with no improvement and the second one has replaced the fuel pump and although it has improved slightly the problem is still there. Help please I want my Toyota back!
