Car putters then dies.

Post by subaguy »

2003 Subaru Legacy sedan aprox 52k miles manual transmission. Driving down the road car sputtered bucked then died. Would not restart. Called tow truck waited aprox 3 hours car started ran and drove for about 30 secons to a minute died again and would not start for another few hours. Then same thing starts runs for maybe a minute then dies.

Welcome to the BBS.

Is the check engine light on when the engine is running? I'd suggest trying to pull any codes from the ECU with a code reader. Most autoparts stores can do it.

I kind of suspect your MAF sensor may be the problem.

The check engine light does NOT come on. None of the lights come on.

Can you elaborate what you mean by none of the lights come on?

When you have the key in the ON position, but the engine not running, does the CEL and other warning lights come on?

Mass Airflow Sensor.

Is the the black or silver cylindrical looking thing bolted to the top of the airbox, and has the intake piping coming from it to the engine throttle body.

The engine computer uses the MAF sensor measure the air entering the engine so it can correctly determine the amount of fuel to inject.
