Subaru Repair: Subaru Baja hiccup..., spark plug gap, poor gas mileage


Question
QUESTION: 05 Baja in Las Vegas (HOT!), 38K, new plugs, wires, air filter, and oil.

Symptoms:
1) Poor gas mileage (i think nEwayz) I'm getting about 18 MPG, 75% city driving.
2) It dogs on takeoff sometimes, like it's flooded.
3) While in drive at a stop light idling at around 750RPM's i experience a random hiccup that actually jogs the whole car a significant bit. First time it happened I thought someone bumped into me. This will happen about 5 or 6 times as I wait for the light to change. It's not repetitious like a misfire though, its sparatic. Happens only when the AC is on (which could stand to be charged it's not blowing really cold anymore) but I don't think its AC related because just putting the car in neutral raises the RPM's enough to stop it.

ANSWER: I would double check the spark plug gap. Also it is possible though it is rare, that the front or upstream oxygen sensor is failing but not enough for the computer to see that. I would bring it to a repair shop for further diagnosis just to be safe and to prevent throwing parts at it.

QUESTION: you're a fuckin moron

Answer
MAYBE just maybe you should pay for a DIAGNOSIS instead of trying to get one for free. Remember, I do no have your car here, it is not hooked up to my machine for diagnosis and I have not test driven it. So next time you call someone for free ADVICE and you are given some, don't kick the gift horse in the mouth. And it is nice to know how childish some people can be. Have a great day!
