2000 454 rough idle and acceleration while cold
I’m stumped and hope someone can help. 2000 454 k2500, hard starting, will crank forever unless you give it some gas and it’ll stumble to start, but once it does it idles at 750-850 rpm (normal?) but seems to have a misfire and you can smell gas out the exhaust. While it’s still cold (100-120 on...- 00CrewCab

Diagnosing Rough Idle Hell

99 350 vortec rough idle
I'm not any good at diagnosis, but my 350 vortec doesn't idle nicely, cold or warm. It kinda pulses(?) or it seems like it has a cam in a way, If that makes sense. Going down the road if seems to do alright, but as soon as it idles it's not nice. What do you fellas think? IAC, tune up, something...- Raspi454

At my wits end.. Looking for any idea.
Okay, this may be a long post so apologies in advance. I have a 94 1500 with the 350 TBI. I have owned this truck a little over a year now. I bought it with a blown motor because P.O decided to run it hot and then put water in the coolant and it froze and busted the block. Regardless, found a...- Shane Dyer
