hi, since i changed my air filter/ plugs/ rocker cover/ gasket/ seals the car feels like it has been under-performing. when i press the throttle, it feels "heavy", like someones stuffed a sock in the air intake and its struggling to get enough air. when it used to run well the pedal would feel light and the engine more responsive, now it just feels sluggish. i notice it most when accelerating in 2nd or 3rd from 2-3rpm- it drives like its accelerating up a hill.
unfortunately i launched the old plugs and filter so cant see if putting these back will fix the problem. the new plugs are bosch super 4s and the filter/gasket/seals are fiat.
the car feels the same whether the engine is cold or warm. temperature gauge sits between half and the notch below when properly warmed up.
i tried the car without the air filter and it was obviously more responsive but still not good.
i tried disconnecting the MAF sensor and the performance didn't change.
no tell-tale lights on the dash (apart from when i disconnected the MAF.)
if anyones ever driven a car with both a short pipe between the filter and air intake system, and then a CAI kit with a long pipe, you'll notice you get better throttle response with the short pipe. well, at the moment i have a short pipe but it feels like the pipe is about three metres long.
i tried an ECU reset but no joy. I left the negative disconnected over night and when i reconnected i let it idle for five minutes and turned it off. then i just drove a la normal, however the engine never really warmed up as its only 5-10 minutes to work. is this the best way to reset or should i just drive normally after the reset?
i had the same problem with my honda integra. i'm pretty sure it's not just me as i've experienced the best side of both cars. at one point with the integra it got so bad it wouldnt even accelerate in 4th gear. never did solve the problem. changed a load of stuff and had it on a rolling road and everything.
