Customer Question

I have a '96 cad Eldrorado. It has the cross way engine. I had to replace the starter which is under the intake manifold. This entailed removing all of the stuff on top of the engine.
On reinstalling everything I put all new o-rings on the injectors and new intake manifold gaskets. Everything seemed to go well and the engine runs perfectly except now service engine light comes on. I can remove the yellow engine light but it will come back on again the next day or two. The engine still seems to run perfectly.
I disconnected the fuel lines to do the repairs-- could I possibly not have pushed them back together tight enough or ?
I have to have the car inspected by state to renew the license next month so everything has to be good on the emissions test.
Thanks for your time.

Im sure it has nothing to do with fuel lines especially if it runs good. You either caused a vacuum leak or left a sensor disconnected. Can you scan the car for codes?
