V70 rpm high fluctuation at idle and engine stops

I would start by unplugging the throttle position sensor then start it and see if there is a change. Could also be the slow idle sensor or the crank position sensor? Have you looked that code up or had it computer checked? most the auto part stores here will let you use one in the parking lot hope that helps

Idle Rpm Too High.

A high idle is caused by either a massive vacuum leak or a sticking idle speed control valve. I would think you have a vacuum leak, use a can of carb spray and shot around the top[ of the engine, if you hit a leak the engine will sound different, repair as needed.

Should the oil pressure gauge fluctuate with speed

The oil pressure guage will fluctuate with engine RPM. At idle it should be approximately 20 lbs./sq.in, at high revs about 50-60 lbs./sq.in. Hope this helps any concerns you may have. Good luck!

Honda Accord 1991 idles high then low

)The fact that thge engine idle fluctuates when it is cold indicates that the Fast Idle THermo Valve is out of adjustment.
This valve is located ot the front of the intake manifold on the driver's side just below the accelerator cable. To adjust it, wait until the engine is cold (best to do it first thing in the morning).
Remove the two screws holding the cover on and start the engine. There is a brass needle sticking up through a plastic ring that has two slots in it. With the engine idle fluctuating, use a thin flat blade screwdriver to SLOWLY turn the ring CLOCKWISE
until the idle stabilizes. Once done. put the cover back on withg the two screws and you should be done.

It is your Idle Air Control Bypass Valve . It is located on the back of your intake manifold. Unplug electrical connector to it while idling then reconnect. idle flux should stop temporarily. It can be bought on ebay for between $100-$150.

Hi,
Please check your fuel line and has it cleaned ( if you have not touch the accelerator).
Seems your AFR is fluctuate changing that cause your car has unstable RPM.
Observe your fuel pump, filter (fuel and air).
Other things need to check : Your high tension side for 'half ( 1/2) faulty' .Your ignition cable, distributor and spark plugs must observe.
Your coil seem still working fine
