check the potentiometer.

Netken, please, after you clean the idle valve and check de O2

sensor, have to chech the Pot. The voltage between pin 2 a

ground has to be 700 mili volts or .7 volts, engine running. If It

doesn't match this value, trie to get it rotating POT right side a

little bit down or up direction. For do that, may be, you have to

disconnect the Pressure Regulator to get access to the POT cap

and 4 screws. The two left screw, under the cap, are using as

pivot t, losse 4 screw only little bit. Conect the Pressure

regulator, star the engine, instal the Multi voltimeter red at Pin 2

and Black to batteri ground. Take initial voltage readings

between Pin 2 an ground. If its different than 700 Mili

volts, then rotate Pot right side very slowly, few degrees, lucking

for to match 700 Milivots, +/- .250mv. You will notice the change

of RPM when you rotate the Pot a little bit.

iF YOU dont match .7 volts, after ROTATING THE POT, may be

you have to graduate the tiny screw on the front of the Trim Pot.

Read the Chris Marteen, Jay 300, Sbourg, Threadid and others on

06-25-2003. and "AIR FLOW METER POT SOURCE - BOSCH CIS"

ON 05-25-2003.


Good Luck.
