trucks acting weird
 

ok well its throwing a code for the egr valve curcit "A" i just replced the egr valve but its running like poo and also when im driving there is a really loud rattling noise almost like rod knock but its deff. not cuz its only when im in gear and driving like i can rev it in nuetral and it wont make the noise but if im in gear moving it will what do ya'll think tranny? rear end?
what do i do about the egr?



thanks in advance guys

So its more of a rattle then a pop? Is the driving doing anythign wierd.. bouncing a little, or locking up when you come to a full stop? I've got a coupel ideas, but they are all abstract from each other unless theres a tad more info on the situation :-)

umm yeah its more of a rattel its not doing anything weird when drivuing

So, Did Anyone Ever Find Out What The Prob? I Have The Same ..

It could be the timing. With the timing controled by the PCM along with the cam position sensor anything could happen. You need someone that is real strong in the PCM workings.

Maybe you'll have to visit a Ford shop.

i work at ford since it only does it when its in gear it may be the flywheel or clutch
