My wifes 95 Leg 2.2 has been hard starting when

it's cold.

 

Now she calls me and says her MPG was 14.5!! And

smells like it's running rich.

 

The cars had:

 

*New Coolant Temp Sensor

 

*New Fuel Filter

 

*New Plugs and wires

 

*New air filter

New O2 sensor?

Has anyone checked the fuel pressure regulator operation?

this might be a dumb question , but has she changed driving habits, meaning shorter trips , more idling, both my subaru's are 2.2 1 is 95 other 1 is a 97 , the 95 gets around 22-23- mpg, the 97 gets 24-25 mpg, and both have 170,000mi om them , i have done everything possible to the 95 to get better mpg, , but i make short trips with it,

I got down to 14 with a bad O2 sensor, Replace the front one with an OE. I had an aftermarket and it only lasted 2 years (for the record I did not install it or buy it).

 

How many miles on the car?

When was the last time a timing belt was replaced?

Would that make for hard start when cold too??

She has had it scanned for codes twice with no

codes showing.

 

How many miles on the car?

 

Like 115K or so.

 

When was the last time a timing belt was replaced?

 

I am guessing but for sure no more than 20K ago along with

engine seals, water pump, etc.

I don't remember all the brands. NGK plugs and a Borg/Warner

sensor.

 

All parts were top quality.

We are attacking one problem at a time. The O2 sensor needs to be OE.

 

Hard starting can be a fuel pressure issue, can be runing too rich becuase of the O2 sensor and fouling the plugs, but generally fix one issue at a time. Also get the codes read, see if any are stored, and then reset them and lets start with a clean slate.

 

Also describe better the hard starting.

When cold the car starts hard. She has to give the pedal

a little gas to get it to go. To much and she then has to

keep it to the boards. Runs rough for a few seconds then

it's fine. Once warm, even after sitting an hour or two, it

fires right up.

 

Codes were read twice in the last month with nothing showing.

We replaced the coolant temp sensor anyway. That did nothing

but empty the pocketbook.
