Hello
Lane Daling,
From washington state. I hope to get some knowledge to get my 98 grand prix running again. When I push it or need power to go up a hill it act like it has a goner on it at about 3000. Then It throughs a code P0171 and p0300. Not sure what's causing it for sure. Greatly appreciate any advice.
Thanks

1. Clean the MAF sensor.
2. Inspect all vacuum and PCV hoses, replace/repair as required.
3. Inspect all hoses and connections in the air intake system.
4. Inspect and/or test the intake manifold gaskets for leakage.
5. Check for a dirty fuel filter and proper fuel pressure.

P0300 - Could be plug wires, plugs, coils, or caused from the lean code.

Was going to post this. 171 (and 174) lean codes are most likely a post-maf leak. P0300 is most likely the byproduct of of the 171.

Another guy named Lane. We're taking over the place.
