my cars acceleration

[brownale01]

yer was on a 1.2 but defo wernt the ecu cover, we checked, double checked, wrapped up and everything on that, we thought it was to start with as we mucked about with it and seemed to stop it but then came back so just wanted to get rid in the end

Wondering if these issues may be down to the head in need of a recon?

 

[franx]

get a diagnostics check, think it may just be down to throttlebody or throttle posítioning sensor (meaning accelerator i think?)

i've read a few threads sounding like your problem.

Are the home U380 readers any good to diagnose this type of issues or still a trip to the stealers?

Cheers

Defo wont be anything that can be solved be pulling the head to bits.
Is it drive by wire ?

 

[bearne1]

I think it is drive by wire, it's a 2002 FF 172. What were you thinking?

Thanks

is you car modified in anyway?

just going off you saying the car revs to 8K

 

[bearne1]

Car has K & N Panel filter, performance back box and matched inlet. Had these problems before any of the modications.

Thanks

Sat in traffic for nearly an hour today and I am sure this problem is getting worse! Cannot afford a CLIP test until the end of the month so any help appreciated.

Idle is very rough (missing badly) and problems only during low revs (i.e. between 500rpm and 1500rpm). No stalling though unless pulling from a hill with low revs.

No dash lights come on, just becomming a pain in the arse!

Many thanks

Think this is the closest solution:-

Guys, on a level road try lifting the clutch pedal very slowly to start the car moving without giving any gas! I`m thinking it might be something to do with the fly-by throttle in some cases. Mine happens if i actually use the throttle whilst im lifting the clutch. If i start the car moving without the throttle its smooth. Its almost like there is a dead spot on the throttle pedal and the car nearly stalls.

Just hoping there is no problem with the clutch..............

 

[bearne1]

What is most likely to affect the weak idle, the TB or the throttle pedal?

 

[bearne1]

Disconnected the plug on the throttle pedal today and acceleration seems better again?! Have I reset something by doing this?

My 182 since i bought it (30k miles) it is slow to react to acceleration up to 5k revs then it's like it has a turbo boost and I'm shot from 5k revs to 8k revs in no time at all, incredible acceleration. I'm not sure if this is standard or not, it doesn't cut out or any other problems on revving

The sparks aren't included on your standard Renault service with a 182 if I'm correct as they cost way more than the standard ones.

That'll be the 5k kick. Quite normal.

 

[bearne1]

Right, nothing on clip at all. Renault technician (experienced chap) noted problem but could not diagnose.

I am lost with this, but have checked and when I press accelerator slightly and hold pedal the revs fluctuate constantly. Does anyone have any ideas?

I'm lost!!

i had the same prob with my 172 its the way they are its an electronic throttle and the response is slow on them compared to a cable throttle the best way to do it is give it half throttle then full throttle

 

[bearne1]

If it gets gradually worse surely this must be fixable?

Thanks for the reply, what do you mean by half then full?

 

[bearne1]

Anyone?

Thanks

Forgot to mention, I also have a very rough idle (not normal as they do miss slightly).

Thanks

Anyone?

Just wondering what else I could try!?
