My car is burning gas fast. I just did an oil change and filter. I changed the air filter and I redid the break lines all around. I replaced the fuel line and filter I replaced the water pump and I did a upper and lower intake manifold gasket change and seals with a new thermostat because I needed it done, but it seems to now be going through gas really fast. What can it be or do you think?

Recheck work on intake manifold as it may have a gasket leak. Check vacuum at intake and if below 15" at idle it probably is. Try spraying choke cleaner at gasket area then scan for codes.
