Does the gas smell go away after driving for awhile?

 

I get the same 19-20 MPG in short trips around town on 10% ethanol regular gas, plus a very strong gas smell on start up. Gas smell goes away after a minute, so I've never worried about it. It does smell toxic at first, though.

 

My MPG improves to 22 mpg on trips at 75mph with AC off. Absolutely no codes. All new ignition parts. It's just the way this car is with an AT.

 

I'd replace the car with something with better MPG, but I don't drive it a lot of miles, and just the sales tax on a new car would buy a year's gas.

on my 95 legacy L wagon ,a/t 2.2 , 165,000mi , no codes, mpg is only 19 , new oem plugs, /wires, fuel filter, air filter, cleaned maf, cleaned egr, new cooplant temp, different tps, new crank sensor, new pvc, could i have the tps not adjusted right or needing 02 front sensor, or needing a new cat,

 

This is my story http://www.ultimatesubaru.org/forum/showthread.php?t=88646

yes only at start up , compaired the 97 legacy with 2.2 a/t same everything , the reading on the fuel trim is the same as the 97,

 

1. Are you sure you replaced the ECU temp sensor and not the one for the gauge? I ask becaus ethat's the kind of mistake I make, but since your codes don't show a prob there, this is probably not it.

 

2. I also have a 97 Legato (Leg-auto 2.2) and had gas mileage problems. Did all the same changes as you and got it back on track. Now get 27 AVERAGE, 16mile 50 mph commute. Very happy.

 

3. I also still have gas smell at startup, and I think it's plain too rich for this older (165k miles) engine. My theory is that compression is down due to tired rings, so less air is ingested, but same fuel amount, based on temp only, is injected, while cold.

What I want to do is put a 10k-20kohm resistor in parallel with the temp sensor, which will flatten the resistance curve. Leaner when cold, same when hot.

 

4. (Not likely but...) Brakes dragging? I noticed caliper piston locking on the 99 Forester we also have and that need to ba addressed (uneven pad wear indicated).
