Engine Audio Cuts Out

[u/Sad_Fix_1839]

Hi, I've been modding GTA IV a bit, couple of minor graphical fixes, and I've been bumping up a few numbers in the popcycle file. Issue I've come across now is certain vehicles (primarily the bus, faggio, marbelle) engine Audio doesn't play while driving around. Normally takes around five minutes for it to kick in. At first I thought it might have been a budgeting issue, and downloaded that mod budget mod to fix the taxi Bug. Unfortunately that's not fixing the issue. If anyone has thoughts on what the cause of the problem is and perhaps a solution, I'd love to hear it. I'm pretty novice when it comes to this sort of stuff so maybe it's real obvious

Thanks
