Hello all. I recently connected a tester to my 86 E250 van with a 5.0
liter motor. The code came back as an 84. Checking the book it refers
to the EGR valve vacuum control solenoid. When I checked one of the 2
solenoids it had an infinite resistance far out of the ohm range
stated. The cost for this assembly (2 solenoid valves mounted on a
plastic bar) is $80.00 +/- . The vehicle doesn't seem to be acting
strange (odd idling, stalling at lights, etc.) so -- is it worth
spending this money to repair it? By that, if its not repaired can any
damage be done to the motor? Will my gas mileage suffer? Some posts in
the archive state you must fix it or else while others advocate just
blocking it off and saving the money for a night out. Any help
appreciated....  Thanks...
