Default HELP ! Check Engine Light came on .

Check Engine Soon light came on. A friend pulled the code 34. My service manual says M.A.F. sensor. We reset the code, and it came back on after just a few miles of driving and the engine was started. Before I replace that expensive part, is there something that may have caused the code to set. 1988 Stock Thanks for any help. :cuss

Two relays need to be changed just to be safe.
