Recently started to drive N/A MR2 and it consumes really lot of fuel.
![](./images/smilies/spacer.gif)
It's very similar to my track mr2 which has around 300hp.

Maybe these point would shorten the list of causes:
1.

Lambda was changed to Denso not so long ago
2.

There is

"sport" air filter and free flowing exhaust fitted
3.

Brake calipers are not seized

Water temp gauge acts very strange.
![](./images/smilies/spacer.gif)
Firstly, it goes to operating temp

(just a little less than half), then it sometimes goes all the way down and then goes back to regular point.

I don't feel anything to engine's work when gauge is fluctuating, so I guess it's only gauge itself or sensor.

There are some problems with idling speed.
![](./images/smilies/spacer.gif)
When the car is started from cold, idle speed is around 1k rpm
![](./images/smilies/spacer.gif)
(at this point I think it's running very rich) and then slowly after a minute or so it goes up to normal
![](./images/smilies/spacer.gif)
±1.5k rpm point.
![](./images/smilies/spacer.gif)
Then it slowly decreases when engine is warming, but when it's fully warm, rpm stays at around 1k.
![](./images/smilies/spacer.gif)
So it's a bit high.

Today morning I started a car with a fuel gauge showing half of tank and drove to work about 6km.
![](./images/smilies/spacer.gif)
After this
![](./images/smilies/spacer.gif)
"trip" fuel gauge dropped by 2 points.
![](./images/smilies/spacer.gif)
When I parked the car I even checked for fuel leaks as this drop really shocked me.

Any help would be really appreciated.
