Question about 2006 Volvo S80

1 Answer

'99 s80 t-6 intermittent lack of power

The car has 171k, all recent software updates. When warm, it will intermittently act as if it can't get gas. it will idle just fine; you could "floor the accelerator" and you get no change of RPM. Then, it will be just fine again. What's up with this?

It sounds as if your electronic throttle module is failing. This has been a big issue with volvo's since they put it on in 1999. The newer modules are much less troublesome (2005 and up) Dealers installed price on one of these can cost over $1000.00 USD seek a volvo independant to assist you

Temp gauge pegging out, but engine isn't hot to the touch.

You could replace the sending unit to cross it off the list of possible problems.
You could check resistance cold and then with the engine at normal temp too. The gauge on the dash could be faulty too.

Hi. I have a 99 camaro 3.8l and I'm having some

Sounds like a fuel problem,You did the coils,plug wires and sparkplugs, that should of taken care of the misfire,You may have a EGR that stay open and doesnt close properly and it doesnt set a code why the ECM compensate for the false air.Now this causes rough idle,and smooth cruise with no misfire until you get to stop or idle speed.The map sensor this can also fail when warm especially if the vacuum it is suppose to get is not met. And a failing MAP causes a lack of power. A TPS failing causes a stumble and lack of power but no misfire.cansmo_184.gif

Sometimes when i press the gas pedal on my 99 accord all the way down it acts like its needs gas. What could it be?

Hi there,

For an engine to work properly, the fuel air mix must be within certain parameters. Too much fuel uses up the available air before the all the fuel is burned and causes the engine to 'stumble' (a momentary lack of power until the fuel/air ratio has been restored). Flooring the pedal can certainly cause these symptoms.

When this happens, it's lack of air, not gas that causes it. Check your air filter as a possible cause, it may need to be replaced.

Intermittant no start..

Did they check the wiring in the ECM wiring loom? The car's computer would have a separate wiring and have a lot of them inside compared to the rest of the car. This happened to me once and had the car ECM rewired because of it.

1985 Toyota Corolla Intermittently runs rough-no power

Try this: Remove the two (primary & secondary) vacuum diaphram covers & inspect the vacuum diaphrams. If there is any evidence of distortion at the diaphrams, expect to get the condition that you are describing.
