Jrice posted a topic in Cadillac CTS, STS 2005+, 04-09 SRX, CTS Sport Wagon (Sigma)Hey guys I have an 04 srx v8 northstar. I just purchased it with a known misfire #7. I through a set of filters and ngk plugs and coils at it and now I only have a soft skip at idle. It gives me cylI Der number 8. I changed the plug coil and injector to different cylinder and no change. Also did compression and that was good. I have 15inhg vac at idle and needle jumps a little with the skip. If I unplug number 8 it gets much worse of skip. Fuel pressure running is 60. I left gauge on for the day taped to windshield and one trip into store it had dropped down to 15 psi in 30min. But only that one time. I did intake gaskets also. When doing that I noticed a few different cylinders had new valve seats. Front of motor is dirty so I'm assuming awhile ago it broke chain and eat some valves. But last owner was great guy and he had it from 80k to 110k when I bought it and knows nothing of it. I had the car stall today when going from reverse to drive and it gave me a good misfire after p0300 and p0308 and also a p0019. Not sure where to go at this point.thanks in advance
Crazy_Jake posted a topic in Cadillac Deville, Eldorado, Seville, Fleetwood, Sixty SpecialSo after failing emissions twice for HC (CO and Nox close), I decided to pull the intake mainfold (beauty cover) cover to inspect. Fuel is everywhere inside. Thinking FPR. I'm trying to disconnect the injector harness where it goes through the plastic fuel rail holder. Doesn't look like a connector really. See picture below: BTW, that cup where the wires go through was filled to the top with fuel. Fuel kinda looked like some oil in it too, but not sure how that much oil could get in there. I think it's just old fuel that has evaporated over time and "thickened" so to speak, also mixing with the plastics. I'd really like to remove it so I can clean everything up and inspect wires. Any help would be greatly appreciated. Thanks gents.
