having some problems
a week ago my truck wouldnt run, anytime i would accelerate it would lose rpms and want to stall
it smelled rich and ran really rough
when i reved the engine and tried to keep it at a steady rpm it would drop and make a lug sound
my mechanic looked at the egr valve and did somthing with it and it worked
recently it has had a hesitation accelerating, it stalled yesterday and i turned it back on and it worked fine
it still hesitates and rpms fluctuate in park somtimes
it doesnt have a vacuum leak and i seafoam cleaned it
any suggestions?

 

Had the egr solonoid replaced and pcv valve
