I have a 92 hilux 22re. Has some vacuum problems i think. It idles low while in neutral. Does anybody know a good mechanic in Minneapolis or st. paul area they can suggest. I have tried to use the code reader, but most of them will not read anything. Thanks

code reader isn't needed on OBD1 toyotas, short TE1 to E1 in the diagnostics connector and turn the key on without starting the engine and count engine light flashes.

Vacuum problems won't show up in codes, OBD1 is quite limited. OBD2 won't even tell you if vacuum lines are unplugged, it'll show up as an O2 sensor code or lean bank code. about your only recourse is to spray brake clean/carb clean and see if the idle picks up/smooths out or smoke the intake.
