Hey guys, I have a 94 k5 350tbi automatic 4x4. I just replaced the egr cave and selinoid as my truck kicked the cel on. It was hesitating on low rpm to about 2thousand then it would clear up. After replacing those parts the truck is still hesitating off the line but no check engine light? Any ideas?

 

I had a 1994 K5 Blazer back in 2002. If i remember right i had similar issues and mine was fuel delivery issues. It was starving either with speeding up or at highway speeds. I started with the fuel filter (very easy under driver side attached to frame) then continued checking the fuel delivery, injectors, fuel pump, etc. I can't remember exactly what it was to fix it but hopefully it helps give you a place to start.

 

I have a new fuel filter and have good pressure, thanks for the feedback!

 

When was the last time you checked the distributor cap and rotor? plug wire contacts? plugs? Also have you cleaned the tbi before? I am trying to remember alot of what i did but i can't remember what problems i checked all for. But they are easy things to check right away.
