hey i got a stock ej8, i just got a full tune up done except for the o2 sensor done about 2 weeks ago cuz the car has felt sluggish and slow lately. well its the same thing if not more sluggish than usual. any ideas what it could be. im not throwing and CEL's. my alternator belt needs to be replaced and my antifreeze smells like fish so i need to flush that. but other than that there doesnt seem to be anything wrong. it just feels super slow. anybody have idea what i should do. and no turbo, nos or build up ideas. i dont have the money for it right now. plus im getting kinda bad gas mileage too. its like 19 mpg, all city. any help wuld be appreciated.

the car has 83k miles on it. heres a list of what i did since i got the car in december.
cv axles replaced
oil change with 10w30 castrol syntec blend
spark plugs
air filter
wires
cap +rotor
fuel filter
pcv valve
timing belt
timing belt tensioner
water pump

i would look into the 02 sensor, ive been getting really bad gas mileage lately and sluggish until 3500 rpm then i feel the power kick in. i get periodical cels but it goes off, i know its my 02, just havent had the $$ to replace yet

yea thats exactly how it is with me. i dont get any CEL's at all but im always driving in town and s**t so i barely ever go above 3500 unless on the highway. and since im always driving usually around 40mph it feels real sluggish.

* so wuld it be the o2 near exhaust manifold or the one near the cat?

change them both if your going to do one, i think the first one regulates fuel not 100% sure though

Replace all the o2 sensors. Your mpg will take a huge s**t with (a) bad o2 sensor(s). And your car will perform like s**t too with (a) bad o2 sensor(s).

Mine felt sluggish untill I cleaned the injectors, they were dirty. Might be worth a try.
