pcv valve how is tire pressure..do not know about pcv valve tire pressure good .Was the catalytic convertor checked? I believe he checked that just had it inspected Could it be that the PCM needs to be adjusted |

Sorry i ran to the Hospital to try and get some relief for this upper respitory infection that hit me like a truck..It could possibly be the PCM But i would like to rule out simple cheap issues first!

I spoke with danthurs back on 3/25. He sent me an email yesterday explaining this:Ya, I still pop in here from time to time, I'm mostly on www.gmforum.com under the same name
Should speak with him?? |
Gas mileage poor
I have a 2001 Pontiac Grand Prix getting 10 miles per gallon in the winter. Just had the car tuned up and the mechanic found the plugs ok, changed the fuel filter and checked the O2 sensor. Nothing else to change?? What else could I be looking for??Mechanic also checked the PCM and said it was fine.

An engine running with fuel mileage that bad should be exhibiting other problems. What else can you tell us about other problems you are experiencing?
You didn't mention air filter. Has that been changed? Do you have a lockable gas cap? Tell us more. |
