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
Those solenoids are about a 'dime a dozen' at "u-pick-ems'
And those valves aren't an aging commodity... some will fail some wont.
Why take a chance... just fix it.
It doesnt have to be a perfect match, either. Just one made to work with
an EEC IV system, and the ohm value should be in same range
Yeh, I'm a Krusty old Geezer, putting up with my 'smartass' is the price
you pay..DEAL with it!
The EGR valve fulfills two functions... first and most important in the
reduction of NOx.... second, it reduces the possibility of damaging engine
While we may consider that an 86 isn't worth the expense of an EGR valve,
surely, doing our little bit to reduce the pollution we cause is worth the
