I have a 1999 oldsmobile silhouette and i got repair code p0452 where sould i start in order to fix it?

All you have to do is Google your codes & read up

TYPE: OBD PO452 etc

You know what the fix is

Go to a repair shop & have them smoke test the Evap
System,find all the problems & make the required repairs

Be a good idea to find a repair shop, like you find a doctor

Before you need one

NEED RADIO UNLOCK CODE TO RESTORE RADIO
IPC INOP. SOUNDS LIKE IP CLUSTER IT'S SELF, COMMON ISSUE

You could try adding power steering fluid and see if it makes a difference. If not, then you might want to replace the assembly

If you have better than average skills you sould be able to tackle it. You will have to remove 3 nuts from the top and 2 bolts on the bottom. Yo will also need a coil spring compressor that you can borrow from parts store (autozone). The most dangerous part is the spring coming lose but its fairly easy t do in your driveway with regular hand tools.

u have 2 bad coils

There is a simple fix... you can unplug it ( a shop can do that in about 1 minute or less.)
It has to be taken apart(transmission) to install a new module.. Unplugging it will get rid of the OVERdrive function.. meaning a little higher RPM at highway speeds.. but will be cheaper than a 1500+$$ job of removal and repair....
