I don't think is running on three piston, but what I feel it is something
like misfire(a little) or something. Don't think is the spark plug or
cable cause it has been changed.

If running on three piston, it would be GREAT as I manage to score
180km/h on the highway Evil. Fix another piston I can reach 250km/h [:-)]

ok, in this case, just go for simple checks first... notice that the
older volvo got some 'tubes' around the combustion system... if one of
them disconnected or bocor, it should most probably cause the 'engine to
shiver'... i recommend u to do simple checks first, ensure all wires are
connected tightly, no 'floating' sockets or wires... also check on the
fuses.... thats all from me... ehehehhe...

hey glock19, I am not old brid lar..mature bird only.. Big Smile still a lot to
learn from other older bird Smile

seanswn, sorry if my previous statement misled you, what i mean is 'it
sound like runing only 3 piston". Here if what I managed to check,
whenever ther start sounding "u tu tu tu " and before the engine run
smooth. I had tried to unplug each plug cable. So far managed to unplu No
1 cable and it seem to be either No 1 cable signal was no transmitted of
it could be No.1 injector problem. Will continue to investigate.

By the way, is your 360 an injection model or running on carb ??

Then better take your injectors out and clean them in some solution meant
for this. The then to clog up after a period of time especially when the
pertrol tank is rusty.

Our GLE injection use Bosch machanical type injection, is not so
complicated if we understand the machanism. I am still not sure if the
injectors that cause the problem.

I had the same problem with my s40, I got the injection and crankcase
ventilator service
and now the engine is stable again..

(I serviced the crankcase because at the same time I got blue smoke coming
out from exhaust when I rammed)

I think you should consider servicing your fuel injection.

I have been having this problem on my Unser for many months. It start
with intermittent idling when stop at traffic light. Send for repair cpl
times but don't fix the problem - it appear to help but not totally and
it get worst and more regular over time. Yesterday send for service again
and the guy change the rotor arm in the distributor. The rotor arm look
bad, and the engine feel much better with new rotor arm. Need to monitor
cpl more days.
