walsh68 Posted February 1, 2014 Posted February 1, 2014 1996 subaru legacy 2.5 i had it scanned came back knock sensor and low fuel pressure. replaced knock sensor and fuel pump light went off but symptoms still there. it will idle fine for sometimes 1/2 hour then start to stumble. a little hesitant when i hit the throttle. maf sensor? will it throw a code because im not getting a light. i just bought this car and i hate to think it is a major . it ran fine on a 7 mile test drive. i haven't done any tuning yet. last week while it was running i tapped on the maf sensor and the car died, i unplugged it and the car died. i did clean the motor and now it seems to run worse. while under the car it looked like i may of had an exhaust leak between the exhaust manifold and motor but i wasnt sure if it was just residue from the motor cleaner. or mabe the cat is backed up. i just dont know!
monkeyposeur Posted February 1, 2014 Posted February 1, 2014 Clean the MAF with a $6 can of MAF cleaner.
spooln30 Posted February 3, 2014 Posted February 3, 2014 You washed the engine with water? Might have to go through most of the engines connectors and clean and dry them then apply diaelectric grease. Works great on my ATV.
Headtrauma89 Posted February 3, 2014 Posted February 3, 2014 Have you checked your fuel pressure? Could be a bad pump or just a clogged filter
