CEL codes...

[jfranson@bellsouth.net]

G'day all,

I recently had these codes pulled...

P0170
P0455
P0300
P1552

I read in Chitown's thread that P0170 is a fuel trim malfunction...

Any ideas on the others??

Thanks in advance.

P1552 is not present. Are you sure? What year/mileage/model? Possibly all are vacuum related if you have an S. Best practice isto change all vacuum hoses and tees, search the forum for how to..

Its always a good idea to include your year trim and mileage when looking for diagnostic help.
