i have an 87 TII and the p.o. was a moron, he had no idea what he was doing, and decided to do everything himself. Based on some of the things i have seen, i am re-evaluating everything. anywho... i noticed that my UIM has 4 nipples on the firewall side and i have seen multiple posts by s4 owners stating that they olny have 3 nipples. i also checked the FSM and it looked like olny three lines lead to the UIM. Do i have a S5 uim? Also, he re-did all the vac lines with "pretty" ones and they are all the wrong size. In re-doing them myself, i noticed no restrictor pill to the pressure sensor. Obviously the pill is there for a reason, but am i going to run into problems without it?
