So I really believe the car needs a cleaning in the EFI. It's 24 years old, needs a clean everywhere. But should I tinker with it. It probably has specific measures and calculation I probably shouldn't tinker with. Or should I take it to an auto mechanic?
just give it a healthy dose of injector cleaner. clean your AFM and intake as best you can, clean and regap your plugs or simply replace if needed. then see if your still not satisfied
