I used starting fluid and sprayed the vacum hoses. I was unable to find a leak. I can't seem to find anywhere that sells the "coffie can" canister. I've tried napa, advance, and auotzone. Any suggestions? I was able to find the black plactic carbon charcol canister that is to the left of the battery @ napa and i'll put that in tomorrow. I did find that the crankcase vent conector hose was disconected from the air intake. I fixed that. Then I cleared the trouble codes and tested again. I'm now getting 172,173 and I'm still getting the 332 egr not sufficent flow. More suggestions please! --jb

 

my g-pa had the same problem.i found that several of the plastic vacuum lines were very brittle and cracked so i had to use clear hose that would fit snug over the lines. i also replaced the egr valve, cleaned the evap canister thouroghly. while doing all that i ended up replacing the tps sensor and cleaning the throttle body.

 

For the 332 code, follow the same diagnostics steps as for a P0401 (well covered recently). Its the same malfunction but on the older OBD-I system.

A combination of 172 (lean) and 173 (rich) is a contradictory condition for the same sensor. Most likely, it is due to a faulty Bank 1 O2 sensor.
