Thanks anyway !

It shoots up then stalls at 4K and yes it only happens in drive I know the factory governs the limiter at 4k In park and neutral but not when driving and it can get up to any speed when driving normally but the second I floor it that’s when the problem arises

Forgot to mention I do have an air intake and headers on the truck would that also be a factor .

Nothing is missing it runs great until I floor it then it gets stuck at 4000 and doesn’t shift along with not speeding up and no it’s not a beater it was well taken care of

I had the leak for quite a few months only because I had no time to fix it . would that be the reason the truck won’t go past 4000 and stop the vehicle from speeding up ? it just seems like a big result of a semi small problem I’m thinking about doing a tune up as well to make sure all my plugs are good anyway .

I have a 2010 Silverado 5.3 vortec and my it won’t rev past 4000 rpm even in manual mode I had an exhaust leak that we thought caused it originally and we fixed it . The problem went away for a bit but now the rpm trouble is back again any help is appreciated . could it Be bad spark plugs and wires or something else? Fuel filter?
