So. I have had my 96 SC 230,000 mile Riviera for a week now, and I gotta say it runs and drives aswome, except the CEL had been on.
Finally got the Scan tool I ordered, and found I had the P1406, and P0171, so looks like I will be searching for a vacuum leak and replacing the EGR. Oh and a 1441, probably from me overfilling the gas tank.
It has all the records and it's had the coolant elbow, at least one done, ( not sure where the other is) but the one by the alternator is still plastic.
I bought the Dorman metal ones and AC Delco o rings.
But just looking at the injectors, I don't think they have been replaced. So I was thinking of just doing everything, injectors, lower gaskets, SC Gasket, elbows, TB gasket.
Does anyone make a top end kit, or do you need a full gasket set or just buy them individually?
