I just bought a used truck and when I got on the freeway my check engine light came on. I took it to autozone and they said it was an egr valve. I replaced the egr valve and it hasnt changed. The truck sputters at high speeds after it has warmed up. I noticed that it is missing a catalytic converter. Could this be my problem?
