flat spot

[fried]

mang! since sunday night after the old road, i filled up BP ultimate at asqutih, which is wehre i ALWASY get my ultimate petrol everyweek...
but since filling up, ive noticed a really bad flat spot specifically between 6500-7800rpm, but also throughout the whole rev range....
is it the petrol?
waaaaaaaaaaaaaaaaaaaaaah!!!! im going to cry... like its a really bad flat spot through out..... and my car feels liek crap!!! why does this alwasy happen to me waaaaah waaaaaaah waaaaaaahhh :cry: :cry: :cry: :cry:

i thought id explain a bit more...

its like a hollow acceleration.... it revs through, and sorta jsut climbs up, but there normal power and torque-iness isnt there.... its jsut hollow...???

vtec doesnt engage rite?

[fried]

im pretty sure it does engage? jsut throuhgout the whole rev range it feels flat and weak..... but from 6500-7800 it just feels specifically hollow and thin....?

BUT if ur right adn its vtec NOT engaging what probelm is that?

[A'PEXi]

[fried]

its like, NOT A HEAVY feeling like my previous problems, it jsut revs throuhg really thin with no power.. strange.... GAHHHH help!!!

Might be a bad batch - hard to tell though.

i think jon swapped ur car with his and did a quick paint job :P

[joneblaze]

bah... if that was the case then it'd run exactly the same as before... ;)

lol...

[Setanta]

what - slow you mean? :P

[SiNH]

Is this a manual or auto?

If manual then your clutch would most likely be slipping, usually occurs in the higher gears.

what - slow you mean? :P

i have never got bad fuel from Asquith...

but i never go just after the tanker has filled up either...

maybe it is your imagination, or the weather, or a sensor is unplugged/loose or your clogged air filter, or your clogged fuel filter, or your dirty spark plugs or old oil or or or or ...

or maybe you over-reved on the OP?

who knows...

[one more chance]

usually due to misfiring but can be because your injectors may need to be examined. either that or a really, really bad batch of fuel...but highly unlikely. run the fuel through, and if it happens to your next fill-up, get your injector flow-tested and cleaned

its very unlikely to be your injectors... i recon check / replace your plugs first.... and also check your ignition timing and basic tuning.
