Hi there, I have a Honda accord, and when it warms up or trying to shift from park to reverse it starts to shake vigorously like its about to have a piston stop working or something, the RPM falls well under 800 and the oxy sensor has died out twice, does any one know the cause of all this?

I have a feeling that the shaking when the idle is warm is the result of a bad PCV valve, could this be it?

But I have no clue whats causing the oxygen sensor to die off so quickly, I'm not using any heavy-duty additives or anything.

I need this fixed before the engine stalls and causes more problems, everything else on the engine seems to be fine, but I did do a tune up, but did not do any adjustments, can you please show me how to them them if there are any mandatory?

Thanks a million in advance!

Hi I just changed the PCV Valve, but no difference, although there was oil in PCV valve and no rattle.

Thanks.

Did this happen before the tune up? Or has problem occurred after the tune up? What was replaced during the tune up?

It started happening last week, I tuned up a month ago: plugs, wires, filters, distributor, rotor.

Now for some reason it starts to vibrate when warm engine and between change gears, (ex. R -->D, etc.)

and there was some oil in clogged PCV valve, you think I should get the throttle bore cleaned, Please show me a diagram of how to, if I should.
Thanks, Molsoncanadian.

Nope, but it was on when the oxygen sensor died for the second time, but I got it fixed, it turned on after about the first 5-10 min of driving, but now I got the CEL cleared-out of the way.

Best and easiest way to clean throttle body is with spray TBI cleaner. Check the idle air control valve on the side of it and remove any carbon in it with the spray cleaner.

Will WD-40 work or anything else sitting in the garage?
I got a carburetor cleaner (spray)

Use only throttle body cleaner, carb spray may strip off the teflon coating and cause more problems.
