My engine light came on the other day and I scanned the codes. P0171 and P0174. Did a quick search and found my system is running too lean and the common problem is vacuum hose leaks.

Well I took it to the stealership and sure enough they told me I had a vacuum hose leak under the intake manifold and that they need to take the front bumper off and loosen the core support to fix it.

They also found I have a coolant leak from the right side intercooler.

This is pretty much all I know at the moment but would really appreciate some help on fixing this without going through the dealers. What are some good replacements for hoses?

Thanks.
