Hey everyone.
I recently bought my first vehicle: a full-size '94 blazer (Engine was replaced. Not sure what year, but it's a TBI too. is there any way for me to obtain that info off the engine or something?). I'm quite happy with it, but I have a few questions about things that I'm not sure if I should be too worried about.

For one, when the engine is warm it idles at about 200-250 rpm according to the tach. That's a bit low for my liking. It doesn't seem to be causing any issues, but it makes me nervous. haha. I've done a basic tune-up and it hasn't changed so I'm looking for the next step.

Any help would be greatly appreciated.
Thanks,
Dink

P.s. more questions will follow I'm sure. haha

 

Is it shaking really bad? Cause at 200 rpm it should be shaking amd stumbling and having trouble staying running...

Post your enging casting number - Kyles a real nerd with that stuff and can prolly tell you what the guys name was that smelted the iron LOL

 

That's the thing. It's still pretty smooth. Every now and then there's a little shudder, and the gauge bounces a tiny bit, but other than that it still doesn't feel to bad.
And I'll put that casting number up once it stops raining out. haha. Thanks!
