Engine Performance problem
1999 Cadillac Deville V8 Front Wheel Drive Automatic 99,000 miles
Have tried every thing. Had heads taken off and new bolts installed. New waterpump, raditor, alternator, starter
car started to burn 4 quarts of oil, every 300 miles, engine quits occasionaly, at stop sign. Then restarts ok. Have changed the following. All new. 2 front oxgen sensors, new valve, with rubber flap in intake manafold, cleaned the maf valve. New plugs wires,
it runs and starts great. Idles at right rpm. Had a code engine rich, then changed oxgen sensors.
we cant figure out what to do to get the oil consumption back to 1 qt. Every 3000 miles like it was before pulled heads. , Why it stalls and quits at stop signs, cold or hot.
and gas milage was 25 to 27 on highway, now 17 to 20
thank you \
