Question: Boggy idle on chevy truck

I have a 1995 chevy silverado 350. Recently my truck started idleling a little boggy. It was sucking air from the gasket below the dual carbs causing it to idle to high. I did changed that and the idle came down of course but it started running a lot worse. I have trouble getting it started after it has been sitting for awhile. When it is running it wants to die once its in gear and break held. Once in awhile it will bog enough to die out. Also there is strong odor of gas in my exhaust. I was told to check the oxygen sensor. Any other advice or possible fix?

It has dual carbs?

A 1995 should be a throttle body injected engine. If you replaced the TBI with a carburetor (esp dual carbs), it may never run correctly if the sensors are still hooked up. And the carbs may need to be synced to each other. I'd have a shop look at it as it doesn't sound like an easy fix.

By Zach Bowman For those who suffer a daily commute through heavy traffic, your vehicle's braking system can bring thousands of pounds of metal, plastic and empty Starbucks cups to a stop hundreds of times before you get to work. It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
