Hello everyone,

I recently have bought a 95 Subaru impreza wrx and have a few questions for those who are willing to help. When I bought the car it was a work and progress and I knew it. I have immediately changed the oil, oil filter, spark plugs, air filter, and fuel filter and drained and refilled the coolant and the car ran great. Maybe a few days or so it would start to misfire at idle so I checked to see if the MAF was dirty and cleaned it with CRC cleaner but it still would happen after about a few hours. I also am getting very poor fuel milage which makes me think its the O2 sensor (no check engine light). I didn't by the car for great gas mileage but I know im not supposed to be getting 200 km(125 miles) a tank. I have ordered new MAF sensor to see if that corrects the problem but I doubt it.

If anyone has any ideas on what I should do I would appreciate it. I live in peterborough

 

Even if you haven't got a CEL the ECU might have recorded an error code. Have a read of the this to check your codes

Also once you get your new MAF make sure you reset the the ECU

 

As above . Are you running standard air box ? Mafs are very sensitive and prone to going wrong
