205 XS Problems
Discussion
I have already posted this on 205gtidrivers.com but thought I would post here as well, just to see if someone may have any other suggestions.
The trouble started last week, was driving back to university and whilst cruising along at 75 or so on the motor way could feel the engine hesitating slightly, almost like a misfire. It seemed quite reluctant to rev freely and generally felt down on power. When on a steady throttle the issue didn't really occur but any sort of load would cause this behaviour.
I made it back but the behavior became more pronounced, and after pulling of the motor way it really struggled to rev, feeling very lethargic and with various flat spots throughout the range. In addition when lifting off the throttle for a second or two and then reapplying throttle the car would die momentarily before the revs would flare back up.
I read some of the previous topics on here and spent some time stripping and cleaning the carb, everything seemed fine but the problem remained. I went to the local peugeot dealer and had a chat with the workshop guy, he suggested that due to the nature of the problem that it was probably ignition based. I have replaced the plugs and leads, rotor arm and distributor cap as well as the ignition coil. I am aware of the ignition module being a weak spot too but this was replaced about 9 months ago. Can they fail that quickly?
Any suggestions would be much appreciated.
Thanks

You're effectively looking at two things that can make a car do that. Fuelling and sparks. Basically just a question of replacing bits until you find the one that's wrong!
Just don't forget to check the simple things first. How are all the filter (including the fuel filter). Is the air filter bunged up? pop in a new one. it could potentially be a fuel pump problem, although from your description of the fault it doesn't sound likely.
Sorry I can't be of more help, good luck!

i think this is the same carb as the axgt from memory.If so it has two accelerator pump jets joined together.They had a tendency to block one of the jets and then drip fuel through the choke that wasn't open .Generally they wlf on full throttle but coughed and spluttered on part throttle.
Checked the battery and alternator?
No point replacing all you ignition system if it hasn't got enough power in the first place.
Blocked carb is a strange one, as a damn good thrashing should usually clear it. When you remove the carb, be careful not to change any of the settings (mixture screws etc) and give everything a good blast with carb cleaner and an airline. Replace any gasket (those sheets of thick cardboard gasket work just fine and you can easily cut them to shape.)
Similar thing happend to a friends XU5 auto - spent ages cleaning and resetting the card as it was clearly leaking petrol everywhere. Ultimately turned out to be the fuel pump.

As a quick update, had the carb off and stripped it down, using the guide on 205gtidrivers, couldn't find any obvious problems but cleaned it all up and made sure the jets were clear. Didn't help. Battery and alternator were replaced fairly recently so unlikely to be them.
I then started having a look at the inlet manifold, thinking perhaps an air leak or something similar may be causing a problem. What i did find was that the vacuum pipe that runs from the front of the inlet manifold to the airbox was cracked, it had split underneath and was leaking air pressure big time. Very hard to spot (or hear) til you were very close. The actual fitting in the manifold was loose as well. A little spannering and some new hose has pretty much fixed the problems. Now revs much more cleanly, seems sorted. Still occasionally seems to hesitate at low revs but I think it might be down to carb icing for now, especially with this weather. The hot air feed has rusted off on my exhaust manifold so could easily be that. Either way the problem is 90% sorted, just got to hope that with some warmer weather that the last 10% sorts itself out!
