if a car is hesitating at low revs, abit like its going to cut out but never does, what could it be?
im trying to figure out whats wrong with mine atm.
it has had a remap on 99ron shell, which is has got in atm ( i thought it might of been due to me running 95 but its had 99 in for a couple weeks)
any ideas?

well im going to check the following :
fuel filter (i have a new one to put on)
ind kit (make sure its not coated in shite)
spark plugs (check for them working loose and see the gaps)
inlet manifold (see if its cracked as its only plastic)
its on a chain which cant slip a notch and it was fine when i put it on, and has been fine for ages after aswell.

checked the spark plugs and they are pretty clean and look fine..
ive moved them into different cylinders but dont expect anything from it.
coilpack looked fine aswell, but i cant see if this is damaged or not, shoud be fine as its only a year old.

nope, its only started doing it in the last 3 - 4 weeks, the remap was done at the end of august.
its going back in for the rev limit raising, so he will double check everything then, but im not sure its that.
a side problem is that my battery light keeps flickering when the car is being pushed hard, ive been told its a sign of an old tensioner on the alt thats packing up (been told by a couple of independent people) not sure if it could be related. (battery light doesn't flicker when it tries to stall)

just done some reading, it could be the coolant temp sensor, as it only happens when it gets warm..
but my display on the dash reads normal as far as i can tell.. always stays at about 92 ish.

it could be a voltage thing if you are getting problems with alt tensioner.

Was going to suggest this while reading down the thread
corsa did simular with a faulty coolent temp sensor as it was making it overfuel and bog down once up to operating temp as it wasnt coming off of the cold start up fueling.
Mine showed up on diagnositcs you had it plugged in?
Drives supercharged Tec with torque

ive had my scangauge plugged in but it doesnt show up as anything.
it might be worth just replacing it.
im also thinking about cleaning the injectors aswell.
