my wife had the 1.4 puma and I have just got her a 1999 1.7 puma ....only bought it yesterday but have noticed when the car hasn't warmed up fully and your slowing down the car starts kangarooing this is the only way I can describe it, usually in 4th gear also when you release your foot off the accelerator the car jerks a little bit, is it cos the 1.7 is more sensitive?? and can anyone suggest what the kangarooing could be doesn't do it when the car is warmer even asked in a garage today they didn't know what it could be.... been serviced today but still does it when cold!!

Can't help feeling disappointed any suggestions greatly received cos wife is moaning UGHHHHH!!!!!

i have a 1.4 and a 1.7 and my 1.7 doesn't kangaroo so wouldn't say it's normal sorry i can't suggest the cause but am sure someone else can

Go to your local Halfrauds, or motor factors, buy a bottle of Wynns injector cleaner, then when petrol tank is near empty, find a petrol station, not a supermarket, fill up with normal unleaded, add the injector cleaner - and enjoy, it wont cure the problem completely straight away, but it will get better in time.

Possible running problems where it runs rich and then lean (kangaroo style) can be the HEGO sensor.
This usually gives a fault code reading of a failing oxegen sensor when on it's way out.
The pattern ones do not last very long and work out less economic then buying a Ford original if it turns out to be this.

thanks for reply,have asked two different mechanics and neither have a clue have never heard of this problem ,tick over is great and drives really well with no misses..just happens now and again when slowing down and acts as if a learner driver kangarooing..will try changing the Hego sensor if above post doesn't solve it will try anything cos otherwise love the car!!! thanks again Mike

Pouring 'snake oil' into your tank won't solve your problem. You need a proper diagnostics analysis.

Mine does the same, it's my O2 sensor breaking down. The OEM versions from Ford will go for a long time before they put the engine check light on, but the cheapo ones from ebay/cheap car accessory shops will last a couple of months and then light up. If you can get hold of a Scangauge or similar, it'll show the fault codes (anything between 0130 and 0135 is to do with the Oxygen sensor). As Kate says, don't buy a cheapo version it's false economy (you gets what you pays for!)

thanks for your replys guys... have changed the 02 sensor still got problem. have seen this problem on various sites but no one seems to solve it.. had new icv fitted its driving me mad taken to garage and nothing showed up when plugged in...now someone is saying the variable timing could be the problem???

Hi Mike

I had this problem a few weeks back, symptoms were the same intermittent juddering usually from start up going into 2nd gear....or around 1700-2000revs. I did a few things which seemed to help but did not really solve the problem; in the end I bought a car diagnostic scanner and it shown the o2 lambda sensor was faulty.

If your car has been running rich/lean theres a good chance your spark plugs are a mess, mine where less than a year old were lovely and BLACK!

I got my 1.7 about 2 years ago and have been slowly working round the car cleaning and improving as I go. Mine has really benefitted from some TLC, I cleaned the MAF, TPS, ICV and it runs smooth now.

Another thing to remember to do is reset the ECU properly... there a link in the wiki explaining the procedure.

Good luck, hope you get it sorted!

One of my HT leads arced over and cracked a spark plug that was what the problem was for me someone else I know had a similar problem but for them it was there coil pack have you checked these? or is it fixed?

[SkunkMunkey3000]

What would you clean the MAF etc with? I've got a couple of aerosol cans of brake cleaner lying around, would that be suitable or would this be overkill?

Theres a similar thread somewhere else at the moment which also says to check a couple of the fuses (can't remember which ones as I didnt get round to looking) but these can also cause errors that produce these symptoms.

You can clean the MAF and ICV with Carburetor Cleaner, if you're cleaning the MAF be careful and do not touch the thin wire inside it, flush it with Carb cleaner only and let it dry.

I took the Throttle body off at weekend it was filthy... and after 2 years of ownership my trottle pedal isn't sticking anymore!:woot:

I used to have a similar problem to this with my old puma, 1.7.
I sussed out, that it only EVER happened when I filled up at morrisons ??
you figure it out, all the petrol in the country comes from the same refineries....but ONLY morrisons gave me that effect, try filling the car up somewhere else would be my advice.......that or TRY the premium unleaded, just for one fill up from empty.....then maybe just once a month or so, put the good stuff in, I normally do this with my bike, and I believe it DOES work wonders !!!
hope this helps, I notice nobody else mentioned this one.....I thought this might have been one of the first things to try, but I will wait and see, I hope you get it sorted out, and it does not cost the earth.

[SkunkMunkey3000]

All the petrol comes from the same refineries but the different companies then add different additives...remember the problems Tesco had a few years ago but no other garages had, I doubt Tesco have their own unique supplier!

[northernmonkey]

skunkmunkey makes a very good point !
as I said, I used to get kangaroo juice only from morrisons....however my new puma does not bother at all, I fill up anywhere, and I've never had a problem.......touch wood !!

hi guys,had the car put into a car tuning clinic on saturday already been on a hand held machine in a garage but they have a £6000 machine cos everything that was a possible cause had been checked cleaned or renewed and was starting to cost alot of money, and still not resolved...they could find no fault codes either but are 99.9% sure its a fault with the cat over fuelling so have booked it in to another garage to get this done on Tuesday another £220 after haggling from £270 but really hoping this is the end...the two guys from the tuning clinic are going to retune for free after so will keep you posted KEEPING FINGERS CROSSED!!! lol....THANKS for all your replies guys really appreciate the help.cheers Mike
