It can't make oil. It must be fuel or antifreeze mixing with the oil. Is it running really rich and flooding the engine out? That would explain gas in the oil. Or do you notice the antifreeze level going down?

What are codes P0133 & P1134, for a 2005 Buick Lacrosse 3.8L V6 with 94,000 miles.


i have replaced an O2 sensor and had similar failure after 1500 miles.
I removed it, chkd it, reinstalled it and it ran fine.
P0133 is related to slow response of O2 sensor. P1134 is mfg specific so google that for ur car.

1992 firebird dies after a few minutes. Had earlier codes - replaced ignition sensor. MAP sensor, O2 sensor, oil sending sensor, new distributor, new spark plugs & wires.. Will sometimes start right...


The Crank Position Sensor dirty or cracked can cause all of this...your parts store should be able to help you locate...not to expensive...hope this helps.

The fuel pressure sounds too low. Is it multi-port injection? Check the fuel pressure against your specs for the car and engine. MPFI systems usually require 40-50 psi.

Car started losing power, died and now wont turn on. Engine light was on for about a week before, checked at O'Rielly's and the computer said catalyst below efficiency (bank 2). What might be


when was it tested at oreillys? was it before it died and failed to restart? if so you could have more than one problem the scanned problem is definitely an O2 sensor but the failing to restart could be from many other reasons. replace the o2 sensor see if it refires. if it does not there are 3 basic things to follow when a vehicle fails to start. does it get a spark, does it get air and does it get fuel. figure out what it is not getting and investigate why and you will find your answer.

Car starts right up but 2 seconds dies, u can start it right up again & it dies again, won't run. has good spark & fuel pressure good when dies


You are on the right track by finding the injector pulse missing.
The computer grounds the injectors based on signals from the cam and crank sensors. You may have to use a scanner to check for trouble codes in the computer and watch the sensors work.
The problem could also be a relay or the key switch.

I wouldn't think catalytic converter, without it giving some indication that it was going bad, but without testing it is hard to say.
When it cranks and won't start, check for battery voltage to the coil on the dark green wire, with key ON. If you have power at the coil, it might be a bad coil. If no power to the coil, it could be a Crank Position Sensor or the Cam Position Sensor inside the distributor. If one of those is bad, it can stop the computer from sending power to the coil.
Good luck.
