#1 Are you replacing the entire unit or just one of the three solenoids ? Best to change all at once. It's held on by two 10mm bolts. And you should always change the seals when ever you loosen the valve or you may wind up with an exhaust leak. And since there are some plastic tubing nearby you need to be careful they don't get too close or you'll melt them.
#2 , If you have an EGR code it is very very possible that it is a pluggage (carbon) problem for my 95 Beretta 3.1 has done this several times first remove the rubber boot that is between the air filter and throttle body then remove the throttle body then remove the bolts holding down the EGR and lift it out of the way look for the small tunnel like hole that runs from the EGR into the intake you can see one side by looking right behind where the throttle body was removed from on the right hand side wall you will have to find something to dig out the little tunnel so that the EGR can sense the flow again and your check engine light will stay off also clear the light by disconnecting the negative on your battery for a few minutes.
there isn't one because there is a vent on the top of the transmission.
There is no adjustments to be made as the computer does it all. If you were to increase the idle speed then in turn you have changed the throttle positioner and that will truly mess up the party.
The head has to come off to replace a valve. That'a a pretty big job.
Pull upward on the hose that the PCV valve is in. The PCV valve will pull out of the hose. The PCV valve is located in the valve cover.
what year, and which engine? Note: if it is newer year, there are two 3.0 liter engines, a 24 valve and a 12 valve. 2000 3.0 liter engine 24 valve
Sepa la mow.....
When facing the engine, you'll notice two small fittings on either end of the valve cover. The PCV valve is the one on your left. Unscrew the plasic cap and replace the valve.
In the right rear of the valve cover.
replace the EGR valve and reset the OBD II Exhaust Gas Recirculation valve
no the pcv valve is under the intake which is pretty hard to do cuz beretta are werid but yes its under the intake in the back
Replace spark plugs and wires Replace fuel and air filters Replace PCV valve
anything over 100 p.s.i. is fine anything under and you either have a bad ring or a valve is not sealing...
