i have a 91 K1500 4x4 with 305 (no catalytic converter). My check engine light kept coming on, so i had it checked (eventually) and was told that the code for EGR came up. So, like all responsible Chevy owners I went out and purchased a new EGR and replaced the old. Now it's important to note that I had absolutely no symptoms of a faulty EGR at this point; No surging, no rough starts, no rough idling, no drop in gas mileage... just "The Code." So, as soon as i put the new EGR on, what should happen but now i have all of those symptoms. And my question is: "Should I just unhook the EGR and stop up the vacuum hoses? Or should I follow this rabbit hole and see how deep it goes?

I'd put your old one back on & return the faulty new one & get your $$$ back. The EGR valve, when it's working properly aids in more complete & efficient fuel combustion (and better MPG) by recirculating hot exhaust gasses back through the cyls. heating the incoming mix, & at $4.00 a gallon for the cat pee that they sell for gas these days, I'd keep it working.

I second that one!

X3, fix it and I would install a new Magnaflow cat converter back on the truck. It will run better with the cat. The new cats are high flowing so the don't hurt performance.

Thanks for the input

Thank you guys for your advice. Sorry I dropped off the planet there. I forgot my password and had an ridiculously hard time getting mine reset. Not sure what was wrong.
