Pick up problem of my punto

ENKI,
it is fast enough but one dont like to throttle more as it is new buy and especially more roaring noise at these gears(1st and gear) ,yeah changing of gears among 1700 rpm to 2500 rpm, i learnt that slowly by reading tachometer(didnt joined TFI at that time).
when one is nearby 15K Kms knows the meaning of "MAKKHAN" and myselves felt better acceleration,smooth ride after 15K Kms.
Things might be different in 90Hp and thats the reason i always say missing 15 Horses....

 

Lol Ganges!! these Multijet's are a bit more than the papers tell you. I like that sense of humor of FIAT. Merely 90 horses are no where enough to propel 1.3 tonne weight to 190 KM/Hr@4900 RPM & 2 Tonne weight to 180@4800 RPM when rear tyres were riding flat on RIM . Can bigger petrol/diesel engines do with more HPs & Torques? Even more astonishing the authority & confidence that they possess whenever they are challenged. Their endurance is commendable for their size.

Even 75 HP achievements are ridiculous for the papers. Did you read the review of diesel cars@Autocar in which Multijets just outplay the Hyundai's big diesels when they are tested in Ghats. The CRDI's mileage & the monstrous torque figures disappear, God knows what happened? The engines feel more & more strained after every 10 mins. It's comedy everywhere. Though it was Ritz diesel which was concluded the best car & not some FIAT but Autocar clearly accepting CRDI's are no match to Multijets in endurance. I am sure CRDI must feel very stress too when they are really loaded. I drove Verna CRDI with 3 people & there was difference felt in performance.

 

Hi,

I am also facing pick up issue in my punto 75 bhp. Turbo hissing sound also not there.Checked turbo and technician told turbo is fine but turbo boost is missing. Car is pulling beyond 2800 rpm in 5 th gear.just 6000 km before did engine work. Checked the Injector and rail in pump house and everything is perfect. Spent around 1.4l but still not satisfied in outcome. Please suggest what I need to do now.

 

I am a;so not getting satisfactory performance right from first 3000 km of my 90 HP.
Now it has clocked 83000 KM. All services done. Cleaned EGR Inlet manifild and all pipes.
Replaced timing chain and clutch. Still no any improvement.

Got problem solved 3-4 times. But problem repeat after using car only for 50-100 KM.
Fiat ASS do some temporary remedy cleaning of vacuum line etc.
instead of permanent remedy.

Now I am going to replace electronic Vacuum optimizer, vacuum tank and vacuum pipes. 90HP comes with electronic vacuum optimizer.
Faulty vacuum optimizer can be culprit. Because vacuum related issues are not tracable via Fiat ECU Examiner.

 

@bhai : Can you share details pertaining to egr cleaning with respect to cost and time required for it? Also does the FASS do it?

 

Hi,

Was the issue resolved? Have you checked the intercooler?

 

Changed intercooler also. No improvement. There is some issue in vaccum line,vaccum optimiser electronic relay fiited near bonnet latch.

This vaccum optimiser relay operates the vanes of variable turbocharger. According to signal from this vaccum optimiser injection timing is also managed through ECU.

MAP and MAF sensors play major role in this type of weired problem.

 

I remember watching a video of an old merc having weird performance problems because of vacuum line issues. Even causing the tranny to shift early and the engine to lose the punch. So, that can be the case but AFAIK, MAF and MAP sensor signals can be fetched via OBD, so that's not an issue. And I hope PCV and related vacuum lines were also checked by them. I also feel that my car is sluggish at times even with a new timing and clutch kit. It would be great help to know how your issue is resolved and I'm an annoyingly curious kid. Hope your problems are resolved at the earliest.
