    1988 5.7 Swap

    Hey, About a year ago, I did an engine swap on my 1988 C1500 from a 5.0 to a 5.7, and it mostly went well. However, there are a couple things I have not been able to work out.

    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...

    I have a 89 c1500 with the 5.7 tbi and I want to get into tuning.
