94 chevy suburban idle problem
hello everyone im new to the site and have a question about my 94 suburban it sounds like it has a miss at idle and goes away when i press the gas pedal and seems fine driving around town but when i get out on the highway it seems to lose almost all acceleration around 50 mph and then comes back around 60 or when the trans kicks down could the 2 problems be related oh yea after about 20 minutes of driving the service engine light comes on and i was told by the tech at a oil change shop that it was an egr code? any help would be greatly appreciated thanks in advance.
