My son has a 2003 F4i with an FI error code 2. The manual says:
- loose or poor connection of MAP sensor vacuum hose
- Faulty map sensor

Would this cause the engine to run rough and make a ticking noise on start up?

I don't have the tools that it says to test these.

:idunno: any suggestions on what my next step is?

Thanks in advance!
