Actually, it can be caused both by game car modifications and invalid car tunning components. I used to play back in 2013 when I had no knowledge about SA-MP on a server, by using a game modification for ZR-350's. Whenever I was approaching ZR's, client was displaying opcodes errors, and after more of this warning, client used to crash, finally. For this reason, I had to remove that modification.
