The one I took out of my blue q90,the large seal was as hard as plastic.
Next time I've got afew days off work,I'm going to do some pressure checks.(Red q90)Only getting about 20-25 mpg on a long run and exhaust stink of fuel.Seems tobe running rich?Want to get to,the bottom of it.
When I do the spray test,I want to renew all injector seals.
