Low Pick Up after quick acceleration

Hi all,
I have a Fiat Linea Multijet (90 Hp Variable Geometry Turbo) and face a very peculiar problem. The car seems to be perfect most of the time. However, whenever I accelerate very quickly, the car responds very well pulling all the way to the redline. But after that, there seems to be a sudden loss in pick up and the turbo takes more time than usual to spool up and becomes highly unresponsive. After diving it for a while, it somehow automatically returns back to normal until the next time that I rev and accelerate hard.

I've tried replacing parts like the Vacuum Accumulator and Accelerator Pedal Sensor, but still the problem prevails. Has anyone got any idea as to what might be the problem ?

Re: Low Pick Up after quick acceleration

Here are the details
Year : 2011
KM : 30500

The lack of power comes up in any gear after a quick acceleration. The turbo seems to spool up at a high 3-3.5 k RPM is abnormal. The initial response is almost negligible and the car feels sluggish. However when I switch off for some time, say 10 or 15 min, then it feels normal to drive until the next time I floor the accelerator pedal.

Re: Low Pick Up after quick acceleration

first you conform engine rpm wise vehicle speed-any loss in clutch 1.Any block in diesel line may create same complaint,first have you finish 30000 km service- you change diesel filter (*), air filter(*),oil&oil filter 2.Vehicle in ideal condition (n,gear) you rise engine up to 3500 rpm-note the pedal feel-release again you rise up to 3500 rpm any different in timing res to rpm-if there is no diff,its due to filter block- give your reply soon

Re: Low Pick Up after quick acceleration

I have given my car for 30000 km service where they changed the Engine Oil, Diesel Filter with sensor, Air Filter and the routines that they follow for a 30000 km service. However, I was facing this problem when the car had clocked just 5000 km.

Normally the car runs perfectly and smoothly. Absolutely no complaints, but when I floor the throttle, usually in 2nd / 3rd gear, I still get the same throttle response and Turbo kick. However after that when I slow down and try to accelerate normally, then the car becomes very sluggish and unresponsive in any gear.It just doesn't pulls in the same way around 1750-2000 RPM and the turbo kick is felt at around 3-3.5k RPM and strangely the engien noise becomes a tad louder than normal.

Is the ECU activating the LIMP HOME MODE ???? ( But absolutely no warning signs appearing on the dashboard )

Even more strangely, after driving sedately for about 20-30 min, the car behave just normal.... Until the next time I floor the throttle.

This has caused huge problems especially climbing up steep inclines.

My doubt here is that if there is any block in diesel lines, then this problem should occur under normal circumstances as well right ??

I tried your technique of rising the engine RPM upto 3500 rpm, then release the pedal and rev again to 3500 rpm. When I did this test what I noticed was
1. Before accelerating quickly : The car takes exactly the same time in both instances
2. After accelerating quickly : There is approximately 1 sec delay in both instances when compared to the previous state(i.e before accelerating quickly).

Re: Low Pick Up after quick acceleration

during low pickup any smoke comes out? have you changed any items in breaking system (break jam), check engine rise corresponding to vehicle speed (any loss in clutch),any humming noise hearing from wheels- fuel consumption /lit ? (you add diesel additive it may increase your Engine performance)

Re: Low Pick Up after quick acceleration

No smoke comes out during the low pick up. I've observed this on many instances. Will definitely try out the diesel additive thing. Thanks

Fiat linea MJD 1.3 acceleration problem

I am facing similar problem since last month. I have Fiat Linea MJD Emotion pk

I have been facing a weird issue with my Fiat Linea 1.3 Multijet Emotion Pk. Occasionally, when on a long drive on highways, I have noticed that the car looses all acceleration for a short period.

At this point, there is absolutely no response from accelerator or gear shift (downshift or otherwise). It is as if the vehicle gets stuck at that particular RPM and speed with only slight deceleration. Obviously, on braking the vehicle, it loses speed and there is no issue with braking. Also, Upon aggressive downshift (downshifting to achieve RPM above 3500-4000), I am able to regain normal acceleration.

There is no error in diagnostic software when checked at service centre. Further, it is very difficult to replicate the error in workshop due to unpredictability of this problem.

In addition I did proper servicing and did all checkpoints as mentioned, still problem persist. Anyone able to give correct reason and solution? So that we could do needful.

Re: Low Pick Up after quick acceleration

I had pretty much the same issue with my GP 1.9 Sport.
Accelerating hard, shifting gear and suddenly the engine seems dead, no power at all.
Release the pedal and put it back down returns the power.

Turned out the electrical part of the EGR valve was busted.
It opend up randomly.

Re: Low Pick Up after quick acceleration

hi, i've been having a similar problem with my fiat grande 1.3 diesel multi jet, up to now its had 2 new egr values, a vacuum tank and now a new starter motor! only bought with 18k on it from a fiat garage now has 30k. and twice now i've picked up with it apparently being fixed to then having to turn back round to hand back! mine has happened both at speed (going from 70 to 30 on the motorway as went unresponsive to the gas pedal) and setting off with no warning lights coming up at the time or on the diagnostic tests. I am at a loss as to what to do with this car! any ideas would be great? have rang up fiat today to put a complaint in and to see if there tech guys can work with the garage to hopefully get it sorted.

Re: Low Pick Up after quick acceleration

Just bought a 2005 panda with 48kmiles FSH. Feels like a new car in 2015! But noticed turbo lag on test drive. On drive home took it up to 100mph which it accelerated up to well and held for a number of miles , decelerated to 70mph and tried winding it up again and experienced severe power loss .........I could only achieve 60mph thereafter! Felt to me like fuel starvation and wondered if fuel cap was venting properly so pulled into next services and unscrewed fuel filler cap enough to let air in. That didn't fully cure problem but made things very much better......which seemed to me therefore to confirm that fuel starvation was indeed the cause. My hunch is that it could do with a new fuel filter and the cause is crud build up over ten years in fuel lines, injectors etc . The previous owner was a lady and I think this low power thing had been pre-existing and was self fulfilling.....the low power meant the vehicle was never spun up properly . The plan is plenty of high ratio mixes of "Forte" diesel treatment, new fuel filter and judicious use of the "Italian tune up". I had a golf 1.9D with a non turbo 1Y engine which I ran on straight veg oil for a bit......inevitably the injection pump got waxed up and the filter and fuel lines got clogged up causing all sorts of running problems . A couple of repeat bottles of forte into almost empty fuel tanks with the "Italian tune up" sorted it. My hunch is that the same will cure the panda.....results to follow. S

Re: Low Pick Up after quick acceleration

........follow on. The old panda had a plastic fuel tank.....has the 2005 one! Or the current one! I ask because as fuel is pumped from a plastic tank , which is flexible , if insufficient air can enter the tank via the fuel cap vent , the plastic tank will squash under air pressure. It'll act as a sort of buffer as compared with a steel tank which , I suspect, would lead to a more aggressive sapping of power by fuel starvation caused by tank vacuum . Just a hunch! I'm gonna have a tap around under it later!
