P1151 and P0174

[kiernan24]

my 98 3.0 v6 started throwing P1151 and P0174.
I've seen some varying possibilities of what it could be. Im going to be driving around 500 miles in a couple days I will definitely try and take care of the problem before than but in case I don't, is there any issue on driving on this for a little while before I get it fixed?

Also, any suggestions on how to fix it would be greatly appreciated

Running to lean, simple stuff first you check for vacuum leaks? Fluid leaking around intake.

A really bad MAF Sensor could do this too but these are O2 sensor codes could also be EGR.

What have you checked so far? Also how does it run?
