5.7 vortec stumbles when I let off the gas. 1998 Sierra
If Im accelerating to say 50 I get to speed and as I let off when I get to the point of let off it bucks one time the faster Im going the harder it is. IT does want to stall if I give it gas off idle or go from reverse to drive it may stall out. but other then that it runs good shifts good. Ideas. Also I replace the MAF but cant erase the codes for it? I was told it could take bunch of key cycles to allow it to be erased. how many ?? I put it on a scanner and it get the same code the one stored. .
