WebBegin by reading and taking note of the pressure at idle and at 2500RPM. On most vehicles, idle back pressure should not be higher than 1PSI. At 2500RPM, the reading should not be higher than 3PSI. If the readings are high at this point, the blockage probably exists downstream of the test point, which typically means it is in the muffler or ...
