problem wit ibiza?

[boyles11]

ive done a search and cant find any thin wit this problem

my car is playin up at the min the past couple of days ill be going down the motorway or a road and in 3rd gear i putt my foot down and the boost gauge goes to bar then starts to splutter and lose boost to under half a bar and then the mph wont go any higher than 80 but if i dont put my foot to the floor it will let me go past 80 then 4th aint to bad but 5th it jurks about alot??? plus it is usin a hell of alot of fuel!!
any one else ever had this problem i aint had the car that long plus its my first turbo car so i dont know a fat lot lol

cud it be MAF sensor cuz i red these are comon problem?

and another question is how do i know my car is mapped cuz who i brought it off didnt no if it was mapped, but i heard standard boost is 6-7 psi? and mine pushes just under a bar witch is 13-14psi ent it?

sorry if ive gone on and confussed ppl lol
thanks

your new here so will give you some slack. PLEASE stop the text speak this is a family forum and there are the older generation (generally the mods )on here that dont understand you, plus it isnt the easiest language to read.

as for your problem, you want to do this:

1) unplug your MAF sensor and see how it drives, if it drives around better than without it plugged in, your MAF needs replacing.

2) on idle, pull 1 coil pack out at a time if the engine note changes, plug it back in and move on to the next coilpack untill you find one where the engine note does not change.. (indicates a faulty coilpack)
if you do have a faulty coil, replace all 4 coils

3) the other thing you want to look at is to see if you still have standard boost pipes. if you do have the standard boost pipes, then i would reccomend getting some better pipes as the standard factory fit items tend to collapse when under load.

hope that helps

As for having a map or not, yes you do have a map. regular boost is about 0.5 to 0.6 bar so if you're on 1 bar then most probably its mapped.

Adam nicely put what you said, the only thing I don't completely agree with is changing all 4 coilspacks if only 1 is buggered. Ok, if 3 are weak and one is totally gone then the new one could overload the others and have them go quicker. But to be honest, coils aren't the cheapest things and unless you got some money tree growing on your back, I would suggest changing the faulty one and having at least one spare in the car (at all times as coils can go quite often)

oh yeah and like said do not use text talk

sounds like a coilpack failing under load

thats what i said, hence the 'change all 4'

i know they are not cheap but i have heard, if you only change 1 or 2 coils at a time, the weaker coils will fail and it will also damage the strong 'new' coils. so replacing all 4 is the best option but as said by reuvers, coil packs arn't cheap.

 

[ian_cupra]

i got 4 bolt down ones for 74quid

 

[ian_cupra]

the problem being, he said it does it on load, so what yuo said wouldnt tell him which coil is knackered!
