So recently i had my check engine light pop up, ended up being a code 34, "egr solenoid". So I cleaned it and tested it by the books, it checks out as good, cel goes off after reinstall. But now the check eng light will come on and go off at random, with no corelation to any factor such as engine temp, load, etc. Sube is running absolutley perfect regardless but the cel has me baffled. Help? Don't want to blow $60 on a new sollenoid and have it not fix the problem, also leery of faking it with a 35 ohm resistor as it could mask the problem.

Mask what problem? The ECU is looking for a 35 Ohm load - be that a solenoid or a resistor..... Though you will need about a 10 watt resistor at least to fake it with. I used a 5 watt last time and it eventually burned out. The ECU just wants something to turn on and off. Doesn't care what that something is.
