misfiring, poor acceleration, runs terrible! Changed coil pack, spark plugs, fixed & replaced o2 sensors and 2nd & 3rd cylinders...still no go!!! Trying fuel pump...not getting any codes!
'Service engine soon' light is on. It states that 'Cylinder 8 misfire' is the problem. I'm hoping it's something simple like a failed ignition coil on that cylinder or a spark plug...
Engine shaking occured during normal driving. Check engine light blinking constantly while driving.Replaced both ignition coils corrected the problem. Very costly.
when i go to give it some gas car starts shaking like, it doesnt stall, it feels like a misfire but not sure.
engine at different times starts to misfire runs roughand some time dies. poor accelerationi have replaced the o2senor on front and back exhaust manifolds and also the mass air flow sensor to no improvments.
replaced front three times with aftermarket. recommend against aftermarket their not reliable. Replaced the rear bank and now getting a misfire code on #7
service engine soon light flashing had it checked said it was #4 cylinder misfire
had this problem replaced coils and everything was fixed coils are very expensive the labor doesn't cost much the part itself was close to $350 total job cost was $800. recommend replacing spark plug with this coil job
Dead miss confirmed by OBD II on no 6 cyl. Replaced coil pac.
car shakes and runs rough due to coil packs needing to be replaced.
car runs ruogh check engin light on says misfirer on number three cylinder.also has crankshaft senser bad.
Front coil pack self destructed at about 126000 miles followed by the rear coil pack at 130000. These Caddys are built like an old AMF Harley...if you like it you will constantly be sinking money into it and working on it every couple of weeks. Typical American car that lasts about 100000 miles (for $50,000) and goes to hell. On another note my Mitsubishi just turned 300000 without ever having an issue and cost 1/3 of my gas guzzling American crap box. Being close to 50YO I have had lot of cars and the Japanese have completely kicked our asses. We have produced nothing but garbage since the 70's. Unless you got tons of spare cash, another car, and lots of patience I would avoid Cadillac and get yourself a Jap car that will last over 200000+ miles.
