My father and mother are on their way to see me in there 1996 Chevy 454
Vortech P30 Chassis Motorhome driving thru a heavy rainstorm.
The service engine soon light came on and my father's book indicated it was
an emissions problem when the SES light comes on in one of these vehicles.
The problem is he cant locate the port to draw out the service codes like I
can in my 1990 Chevy. He cant locate the port, ended paying a truckstop $75
to not locate the port!
Does anyone know where the port is on one of these vehicles????
Symptoms which made him pull over are when climbing a hill, the power and
cruising speed go down. Also cannot maintain a cruising speed of 70 mph.
However, engine runs smoothly.
ANY HELP WOULD BE APPRECIATED
