Engine Rattle(HP gain?)

The other day after school I cranked my ranger up and it had this funny puffing sound from the exhaust and the truck was vibrating a little and the whole way home (3 miles) it sounded live a VW bettle. well my dad came by to check it and found out it was the ERG? sumthin located by the winshield wiper motor and he pulled the rubber hose loose and it was back to normal, he said it was pumping exhaust fumes back to the engine. He said there would be a little more horsepower now( 10% +) I've noticed I now have better acceleration now... anyone else heard of this???

the EGR valve does pump some exhaust back into the engine for combustion, it is necessary for your truck. wihtout it you will most likely start throwing CEL codes. as far as the power gain, it wouldnt be much, maybe .4 of a %

check engine light. your PCM is not calibrated to run without that EGR, and it will not run correctly, turning on your check engine light. not to mention that you probably have a vaccuum hose laying loose thats releasing all your vaccuum. bottom line is, if the EGR is the problem, fix it. dont just unhook it and think your worries are over. it may be ok for a while, but in the long run its going to do more harm than good

cody, first i would make sure that the EGR valve is actually the problem. if it is you can get it at autozone for a lot cheaper than the dealer
