Hey all this on has me stumped I've tried everything I can thing of and nothing worked .. My lil suzi has a g16b it's a 93 lwb nd when mOtor is underload develops a misfire completely the only way to drive it's basically idle roll it allows a slight touch on the accelerator but as soon as pressure is increased it misses .. Now I changed the petrol filter an this made it worse so I replaced all leads and no luck

So if u say it's a g16b I'm guessing ur talking about efi

Are your injector jets clean
Maby broken air flow meter
Air leaks
Clean spark plugs

How many kms?
When was the last time it had a decent service?
did you change the rotor button and cap?
spark plugs?
Injectors properly cleaned, not just an injector cleaner fuel addative.

It's got 245000ish I had a look the injector in the 1st cylinder is very loose and when I turn it there Is a strong fuel smell can't see leak but prob is doea it need replacing or are the rubber seals replaceable?

[buzbox]

Injectors can be fully serviced by sonic cleaning them and replacing the O rings. You might as well get the lot done at the same time. If you take them to a decent mechanic they will be able to sort it out for you.

Blocked cat converter?

[4bthatcranks]

I have a sleeved cat that happened a lil while back so I sleeved that and got 2" sports exhaust

chances are injectors. if not i'd be looking at Fuel Pump maybe reg... but fuel pumps life is about 200k... they'll do more im sure... but at 245k its gettin kinda old

i had same problem, got new seals for my injectors - $20

and cause i had pressure cleaned my engine bay, i had a little bit of water in the spark plug wells, so blasted that out too.

runs mint now!

[4bthatcranks]

cheers eldar0 i looked at the seal injector one was really loose and when engine was on i moved it resulting in petrol spraying out everywhere im getting serviced injectors tomoz for 131 in exchangedfor mine is that reasonable?

[4bthatcranks]

Ordered injectors Friday and got a call 8 today they have arrived from syd Allready woo

Hey how'd you go with the injectors? Fix the problem? Mine is similar kms and struggles to get to 90 up a slight hill with 30". New O2 sensor but no good, economy is poor too 380kms per tank.

[BearX90]

I have poor economy to, but I only have 180k on the clock. I put in a new fuel pump at 178k.
can you let me know if the new injectors fix it?

More than likely an old/dirty air flow meter issue
