, it had these two codes when I got it, p1537, p1538. I checked the imrc and replaced the plastic clips for the actuator arm on the diaphrams, cleared the codes and drove it 25 miles. during that trip the check engine light started flashing and I got 5 codes, p0340, p0300, p1537, p1538, and p0153. can the first two codes cause all the others to happen? where should I start in order to fix this issue.
