S60R jittery acceleration, cause?

Question

When I get the RPM up past about 3500 it feels like the power kicks out for a second and sometimes comes back other times it will just accelerate, but not as fast as it should. Have any of the pros on here heard of this? solution?

Answer 1

Your problem could be a few different things.  Check to see if any of the boost tubes from the turbo/intercooler are loose, cracked, deteriorated.  It could also be a fuel or spark concern, causing a misfire.  You may also be looking at one of several pressure/temperature/air flow sensors on your engine.  It is difficult to diagnose your vehicle without driving it, but these are some places to look.  I recommend taking it to your Volvo dealer, they should be able to help you.  Hope this helps.

Answer 2

it might be a problem with your transmission

Answer 3

it's a Volvo.

Volvo didnt put much engineering into it besides a bigger engine and suspension.

It's not gonna go any faster unless you add a turbo, and change the exhaust system.

BUT remember....it's a Volvo, not a BMW.

Dont expect much from it, even tho it claims to be a performance car.
