Hesitation on throttle kangaroo fashion.

[mikegor]

Glitch this morning for a few seconds. S3 decided to stutter on the throttle for a few seconds. Felt like fuel delivery, so after a couple of sharp revs all back to normal for remainder of journey, which was about 10 miles. I do tend to drive most of time on low revs, could plugs have fouled ??
Decided to get breakdown cover now !! Anyone recommend which is best policy type / company etc.

hi i went with the r.a.c. he put a new fuel pump on mine in a campsite field he worked for his wages that day

Usually built in with classic insurance policy - although I also have AA cover too for the daily drivers in the house

Had the same problem with 'her' car at the weekend (not an S). When it was last serviced the garage didn't do up the jubilee clip after the air flow meter. So when you put your foot down some of the air bypassed the airflow meter resulting in not enough fuel going in with the air. So maybe check for air leaks after the airflow meter?

Also when she says there is something wrong with the car maybe I won't leave it a month before I look ar it ;-)

Must have been the weekend for it; mine was a struggle to start, running rough for a bit for idling ok at normal revs. When I took it out it did a bit of kangarooing, particularly in 2nd gear and was generally running rough. Unplugged the TPS and it was the same; replaced the TPS with another and took for a drive only for things to get a bit worse. It starts poorly and seems to hesitate/fart when I put my foot down.

Anyone got any ideas? I've got a fuel filter on the way in case it is that, done a quick sweep for vacuum pipes etc which all seem to still be in order.

Not sure of original issue but sometimes the new TPS also needs a wiring mod unless it's already been done to your car. Otherwise WOT will signal closed and vice versa should be ok at mid throttle lols..

Anyway not sure if that's why it got worse when you replaced the TPS or not but could be. IIRC ford did a conversion loom for the later TPS.

Good luck all..

Cheers Damian, I've measure the voltage on mine and it seems to read a good 0.46v closed, 4.5v WOT so that shouldn't be it. I'll try fit the fuel filter over the weekend; I'm not overly hopeful that will fix it, but they are cheap and it never does harm to change them!

I had a "kangaroo" problem a year or so ago. it turned out to be dirty tracks on the Air flow meters. Might be worth switching the plugs between the top and bottom meters to see if that helps, its simple and costs nothing. Cleaning the tracks is a bit of a pain and probably best left until you have eliminated everything else.

I had the same thing recently it was the
air flow meter in the end, took it off and
cleaned it with carb cleaner and is fine
now, worth a try

You mentioning the fuel filter reminds me that I had similar symptoms under load where it would almost die but was fine on low throttle or going down hill just before my fuel pump failed

I've also had AFM issues in the past but it didn't really kangaroo but just ran badly and was a nightmare at MOT time.. Problem is all the parts and loom eats are pretty old now.

Hope it's a blocked fuel filter or something simple.
