Suzuki Swift Has Become Sluggish

[w34ponGT]

hey guys my sister has a 2007 suzuki swift. great little car

i was wondering if any of you guys have girlfriends/sisters with this car (their pretty popular)

its a 1.5/ 1.6 auto

when we first baught it had a little grunt to it drove nice

since then its just slowly gotten sluggish and just real slow, not the best on fuel

ive done oil spark plugs new panel filter and still slugglish

ive noticed the transmission takes 3-4 seconds to downgear under acceleration

the intake was very restrictive so i opened it up, helped a little top end and a little tone but still its terrible

so im thinking maybe the cats blocked?

anyone know much about it because i looked on suzuki forums there all dumb cun*s

cheers

Maybe ~ Transmission serviced ($250) and a bottle of injector cleaner ($15)

and yeah check the cat

change fuel filter?

dont use e10(if you are)

diconnect battery for around an hour, on a small number of cars, it can do whats similar to a soft reset, and bring the transmission back to factory settings.

worth a try.

Agree with changing the fuel filter, avoid E10 if possible. Hotwire air flow meter? If so might need a clean out? Hope you can sort it out cause they aren't bad cars for gettin around

il try the fuel filter as i can do it. il do the battery thing and go from there. i would of bashed the cat (shhhh) but theres a secondary oxy sensor and will make the engine light come on

cheers

Just punch/hit the outside of the cat.

If no rattles, should be good.

check if O2 sensor is still working as it should as that can have a dramatic effect on fuel economy

[Marcus89]

is it a swift sport? If so make sure your using 98 makes a big difference. It actually recommends using 98 and the increased economy is enough to offset the additional cost while making the car more fun. On the standard model no idea what fuel is required maybe 95 but likely just standard

[w34ponGT]

its not the sport

if the o2 sensor wasn't working (both of them) the engine light would of come up?

maybe i could clean them with contact cleaner?

[w34ponGT]

the fuel filter is in the fuel pump so the whole thing needs replacing .. which you need to deop the fuel tank to get to

no chance ill be doing that

- Check the tire pressures - could be a little low.

- Check to make sure it is still running light weight engine oil.

- Extra weight in the car. Did she get a big sound system installed lately?

[w34ponGT]

tyre pressure fine

ive opened up the air intake that helped

and started to use 98 bp

and yeh she has one sub in it lol only 15-20kg? shouldnt make a difference?
