    This volvo S70 is non turbo with 100,000 miles on the clock and is well maintained. Never experienced any starting or running problems. After replacing the oxygen sensor the engine light went off and the car drove well until it cut out and would not restart immediately I was wondering if this was some intermitent fault with the computer? could disconnecting the battery have reset the computer allowing to re start. My mechanic will check the fault codes to see if any thing shows up. r

Hi R, As the vehicle started after replacing the oxygen sensor I don't believe the two problems are linked. Have your mechanic carry out a diagnostic scan and we'll go on from there. As a matter of interest, why did you replace the oxygen sensor? Regards John

SOURCE: Volvo S-60 03, non turbo B5244S, has had check

Replace the cat you have ran it for years with a bad 02 sensor so now replace it and you will get better performance and better gas miliage. Never run a check engine light fo a long time it's telling you something is wrong. youer lucky you did not destroy the engine.

Agreed, you can do one of two things. Replace the alternator, or get some new brushes and try out your soldering skills. Good luck.

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.

You can't rule anything out yet. It could be a plug or injector among other things, but probably not low fuel pressure. If you have a code 300 and nothing else, you may have to wait until the problem gets bad enough to set additional codes. And if any of the sensors fail, such as the cam or crank sensors, you'll get a code for those to be tested.
Have the plugs been checked or replaced in the past 30,000 miles ?

Car wouldn't restart even after I had just driven it and it drove well


hard starting, cranking 3 times to start, engine lite finally came on---
1. shows problem with coil--changed
2. problem with O2 in block--- changed.
3. did a fuel pressure check on original pump--- replaced with new fuel pump
3000 miles later had same problems did a fuel pump pressure test again and it would not hold pressure.
upon removing 3000 mile pump it was hot to the touch so it must have burnt out.
just installed another new one (12000 miles/ 1 year warantee)

2005 dodge ram 1500 hemi. will set code 0132 when starting only some times. O2 replaced both sides.


Try changing the coolant temp sensor, it determines when the ECU shifts from open loop (cold) to closed loop(hot)

You fuel filter may have go to the end of it's life and will need to be replaced. Start with the simple and replace the fuel filter, the filter should be replaced every 15,000 miles or once a year to ensure your fuel system is running 100%. the Aveo fuel- filter is located passenger-side rear, in front of the rear tire. Good luck and start with this, keep me posted and Auto Zone can scan your car for the DTC code that your check engine light indicates there is an issue and the fuel filter can be bought there and they can give you the step by step instructions to replacing the filter.

1998 Saturn SL2 engine light


Possible Causes
The following are malfunctions that could cause a rich condition:
^ Fuel pressure too high. Perform fuel pressure test.
^ Leaking fuel injector(s). - Perform pressure leak down test.
^ Vacuum leak around the MAP sensor grommet.
^ Oxygen sensor contamination.
^ Restricted exhaust or air intake.
^ Fuel Vapor Canister saturated with fuel.

IMPORTANT:
If the front oxygen reading voltage is above 600 mV and the rear HO2S is above 600 mV all the time, the O2 sensors are probably not
at fault.

My2005 f250 6.0 l diesel will crank but not start and run


Possibly a crank sensor on or around the harmonic balancer, acts as a magnet like on an old buick. When you get the truck to fire up run it until she gets hot shut it and try to restart if no start continues try spraying starter fluid on the crank sensor itself. What happens is the sensor overheats and wont register that your cranking the engine. Spraying the starting fluid on the sensor will cool it dramaticlly enough for you to restart.
