I have a 97 V70 with 160km on the clock. After the engine heats up I
begin to notice that during acceleration from standstill (eg after
stopping at lights) the car looses power for a few seconds, as if the
engine is starved of fuel or something (I am not an expert). The RPM
drops during these episodes. At first I tried to ignore it but it is
getting worse - to the point where we are holding up traffic
sometimes. The local garage "flushed the fuel injection system" but
this has made no difference. I don't understand why this does not occur
when the engine is cold. Has anybody seen this before? Anyone got any
ideas?

Thanks

My older car, a 92 Chevy Cavalier, had the same exact problem. I solved
it by replacing the spark plug wires.

Many things can cause this problem here are some:

- Incorrect ignition timing
- Clogged fuel filter ( Injection has been flushed)
- Fualty emission systems component
- Incorrect gapped spark plugs or faulty sparkplug wires
- Vaccum leakes

Good luck!

The obvious thing to check is the temperature sensor for the computer.

For the record, the problem was in the distributor as was solved by
replacing the "rotor arm" and leads. Don't know it was affected
by heat but I guess when parts start to go wrong then heat can have
such an effect. Thanks for your suggestions.

Thanks for the follow-up. Yes, the plastic in ignition parts can be affected
by conditions. Wet weather more often brings out the worst, but there is no
reason heat can't do it also.
