Volvo 850 engine in an irregular rhythm and sound. Need help in finding the problem
I made sound recording
I replaced the candles and I had to check and clean the fuel injectors. Is the problem may be elsewhere if the ignition system? While driving a car flick.
Any help appreciated.

By candles you mean Spark plugs right? How is it running on the road? I'm leaning towards a bad plug wire. The jolt (movement) of the engine to me I suspect it to be electrical. My uncles BMW had the same exhaust sound and the engine moved just like yours. It does it more on idle and running was ok. It came out to be a slight misfire from #2 cylinder, sort of like a weak spark. When the plug wire was tested for spark it was fine, but once installed back on the plug it arced. We swapped out that individual wire and it went away. The entire wiring kit costed as much as 2 hours worth of labor at the BMW dealer so we replaced all plugs and wires.
A bad/clogged injector would be similar

Thank you Louiebay for your reply. Spark plugs yes. I did a direct translation of the mother tongue
I replaced today plug wires and that made difference. It is lot better now, but not completely correct. Perhaps because those wires are not new ones too. I got five used injectors too. Have not tested those yet.
You have very good looking car. Good to know that there are still people who love this car.

I respect any person that communicates with another language other than their native tongue. You talk better than people I know here in the states, so your good, I applaud you......you do not have to apologize
Since you are changing your injectors for another set of USED injectors, do them one by one. One at a time and see. Only replace the one that might be bad. If the other set you have were NEW then replace them all but you said they are used. So you are about to use injectors that might be older or worst than the ones that are on your car now.
It's like if you have 4 used tires and u have 1 flat.....would you put on another set of 4 used tires? No you would only put on 1 used tire...... unless you are going to put on all 4 new
You follow?
