I am pretty mechanically inclined so usually I’m able to figure stuff out on my own not this. What happened is I was driving home from work I was in 4th gear let off the gas for a corner then went to give it more and I had no power. Mind you I had music going I turned it down and it had a rough almost grinding noise wouldn’t do over 35 in 4th I live way out in the woods so I had to shoot for home which I did make it not up my driveway though doesn’t like hills. Has a really rough idle and when checking under the hood the IAT sensor had burnt out replaced checked the spark plugs or at least most of them and I redid timing which won’t line up correctly one of the pulleys keeps jumping any ideas ??
