Hi all, I have a '92 pickup 4x4 with the 22re engine, and the last few months, the acceleration has been strange. It's been pretty slow for a while, but lately it doesn't seem to accelerate at all util I'm full throttle. When I first get in the gas, it just seems to run like crap until the throttle's fully pressed down. Any ideas? Thanks!

 

Also, it idles pretty weird. It stumbles and burps until you get into the gas. Thanks

 

EGR, Could be the EGR modulator gone bad, EGR valve stuck open or the green VSV stuck open or closed (I forget).
