Fuel and oil system to be maintained ?
Hi everybody,
Today I made my first oil change and brake pads by myself, it really worth it in my economy
, I also fixed the problem that I had when I take my HHR to a full throttle body cleaning 
, I just cleaned the sensor that is before the full throttle body, BUT yes a but, It seems that I can not get anymore the 23 mpg that I used to get 
, now even after an oil, spark plugs and filters change I just can get 18, but most of the time I have 17 mpg,
My question is, Can you tell me what else I must to replace to get the most mpg? of course apart of oil, sparks plugs, oil and air filters?
I use to buy the best replacements for my HHR, I continue using synthetic oil 5W/30, Is this correct? it sounds and feels excellent with this oil (Royal purple),
I have to mention that when I stop the car, It smells strange, like gasoline bad consumed or burned.
Can you give me an advice about this?
What else I can check or replace to get more mpg?
Thanks for your help

Yes, I cleaned the sensor but I had to, after taking the HHR to a throttle body cleaning I was having high rpm, and I was having a code about high rpm,( It was working good, I just thought that It was the cause of poor mgp)
"the specialist" tried to change the body with high cost $$, so, I started reviewing all possible causes, so I started to clean and adjust all things that they could have move, so I saw the sensor before the throttle body and I cleaned with a solution based in alcohol for that kind of pieces, and after ....'Voila' ..normal RPMs.
And the weight of my foot is not heavy, That why I ask what else should I replace or clean for having better mpgs.
What Ive never checked are the coils of the sparks plugs.
How Could I check these parts?
