Recently my 2006 WRX has been acting very odd. It takes a few seconds to start and sometimes dies right away unless I give it gas for a second. It is also idling like absolute trash, will sound like its running normally then sputter for about 2 seconds then run normally and repeat until I am moving. This happens at cold or hot, doesn't matter and doesn't change pace. As soon as I am moving it completely stops and drives like a champ...
This seemed like it wouldn't be a huge deal but when it started dying on me I think I need to figure out what is up. Also started throwing an all 4 cylinder misfire frequently.
Past and present:
last month I got into a wreck and it messed up the headlight, hood, fender and bumper :shakehead: totaled the car but I bought it back and slapped a new headlight on and shes running good again. The one issue was that the wreck unseated one of the radiator fans and I drove it like that for a while until one night I heard a loud pop and it had cut through my top radiator hose. Of course I immediately stopped and figured out what happened. First I filled it as full as I could with coolant and drove about 3/4 of a mile, saw the needle moving a bit, pulled over and refilled and that made it home. (Hoping I didn't really mess anything up here, never let it into the red...)
Recently (~1500 miles ago) had a new street performance clutch from ACT and a streetlite flywheel installed, thought this was the issue due to the misfires but I don't see that giving me a hard time starting.
Put in a Walbro fuel pump a very long time ago, did not change the fuel filter out at that time like I probably should have, ended up breaking two of the mounting bolts when putting it back together and ripped the wire for the fuel level sensor (no more gas gauge and get a "fuel level sensor circuit low" or something like that code almost every time I start my car.
cam seals were leaking, had them replaced.
ran a little low on gas a while back (~2 gallons left), could this possibly have burnt up the pump?
definite oil leak, can't figure out where from. Seems to be from the timing cover but could be from anywhere, also on top of engine by the oil pressure sensor. smells very bad when I first start my car.
THINGS I HAVE TRIED TO FIX THE PROBLEM (Many from the misfire sticky):
I changed the crankshaft position sensor (had a lot of grime on it when I took it out, normal?)
cleaned MAF and throttle body
reset idle
new spark plugs recently professionally
injector cleaner/ seafoam
timing belt replaced
leakdown/compression showed 125 123 122 123
My next step was going to be replacing the fuel pump and entire assembly so I can have a gas gauge again, but that will probably be a $3-400 that I don't really have, so not excited to keep throwing parts at it. I was also thinking maybe just a new air filter is in order and if none of that worked I am out of ideas.
I really tried to do as much as I could before posting the question on here but sadly haven't even seen a slight decrease in symptoms.
MODS:
3.5" catless turboback
Greddy BOV
performance clutch ACT
lightweight flywheel ACT
Tuned after exhaust and BOV install, 17psi
255 Walbro fuel pump
