Wat car you got mate?

 

unmodified seat ibiza mk4

 

What engine mate? 4 door 5 door? As much info as possible please, will help people help you a lot more!

 

Sorry, it's a 3 door, 1.2 petrol, silver/grey metallic, everything standard no mods

 

Same as mine!!! Does my nut but i keep thinking its jsut the engine

 

what do you mean it goes to idling? Hmmm I got a black 1.2 ibiza mk and sometimes it doesnt feel as nippy as it usually is under acceleration but I dont think it's really a fault with the car.

when my car feels like it's in a flat spot is when i plant my foot down in 4th gear but it doesnt do hardly anything but most of the time there's usually a pull? Anything like this? Maybe our cars are too underpowered ¬_¬"

 

When pulling away at a junction or driving normally, there is a very noticable drop in power, the engine doesn't stop or splutter (which I had on a different car with a dirty fuel filter), the engine speed drops to idling as if the accelerator is not working, lifting off and then replying pressure to the accelerator brings back the power.

It's not the same as if the car is under a heavy load, this is a very sudden change in revs and often causes an engine brake effect.

 

gonna sound daft but check your lambda sensor, i had an astra that did that and was fairly simple

 

i got a 1.4 mk4 ibiza and i notice that when in 1st gear pulling away there is a drop in power (i hit a flat spot)....this is just the engine & how the ecu is setup though..nothing to worry about i dont think.

Can you specify at what revs all this happens? and how long for?

 

I haven't been able to pin-point any particular rev range or gear, it seems to be random, I first noticed on the motorway (little/no gear changes, speed 50-80), but it mostly happened on back roads now (many gear changes, speed 0-60). And so far it's happened till I've lifted off and re-applied the power on the accelerator.

Thankfully I'm alert when driving, so it hasn't got me in any close situations.

 

From what I have read on this forum...this is how the 1.2 engine is.

For peace of mind you can check with your dealers, they will probably ask you to bring it in. There is the possibility that your ECU is returning fault codes. Probably the first thing the dealer will test for.

My Dad had a problem with the electronic pedal control when he had his mk3 ibiza - did exactly what you are describing

 

Some of the VAG engines have drive by wire, throttle sensors basically on the accelerator pedal. These tell the ecu in what position the throttle pedal is in and hence making the car go. Might be wrong, but obviously if the sensor is not working properly then it could cause the problem you describe!

Sure some one will be along to correct me!

A very common fault with the mk3

This isn't a slight lack of power when pulling away, this is a complete and sudden loss of power, and it has only happened in the last week, the rest of the time the car has been nippy.

 

Thanks for the ideas, I think my best option is to take it to a deal, it's looking like it's beyond me or my local garage.

best option mate....by the way on here we refer to the dealers as stealers

 

Yes, just been down the dealers (SEAT camberley, they deserve to be shamed), initial diagnosis they gave after my description, was it was caused by a brake light, cost to fix £120. Didn't like the sound of that, so asked if they could plug it in and diagnose, cost £50.

And then got laughed out the office when I said I would go elsewhere.

 

Stealers!!

 

Hi i have had my brand new ibiza for 3 weks now and last night the enginge the 1.2 suddenly lost power when coming down the motorway didnt stall as it was in gear then it started to accelerate ok again. It has now just as i have been coming hoe from t he shops lost power and the oil light came on the alarm sounded and then the alarm went out and normal service was resumed. the oil level is fine...the bloody thing is les then two weeks old going to the stealers tommorow but what could this be?

 

hi any chance u found out what the issue was as im having the same issue

 

Sounds similar to the faults decribed earlier om this thread - pretty much anything mentioned previously could be the cause

 

got the same problem on a cordoba - drops at around 3-4k. point to mention is that the lamda was replaced about 5k miles ago. ill monitor the thread and post back here if i get a response. i agree its not much fun when your pulling out on the motorway.

 

Try a brake light switch i had exact same problem, it sorted mine out
cheap and easy to fit worth a go,
i would recommend a genuine switch
good luck

 

Did you ever manage to get a fix on this? My 2003 TDI has just started doing the exact same thing.
