gas suckin power robbed ranger

[steve63]

hey gang ,got a 90 ranger thats developing a problem,the truck is getting bad fuel milage ,about 15 m.p.g,but is acting like its starved for fuel,the truck seems to run ok,but while driving ,the power seems to fade in/out like its starved for fuel,the engine light has not come on except for about 15 min after i bought it about a month ago,going to pull any trouble codes it has tomorrow,any ideas?

 

[steve63]

by the way,the truck is a 2.3,5sp,3.73 gear ratio

 

[steve63]

read the codes ,and this is what i came up with- code 34-EVP above closed limit

check that-codes were 34-EVP voltage above closed limit,41-no HO2S switch detected,engine light was not on before test.
