Is it the fule pump?, Spluttering and stalling! Options

[chrispovoas]

Hi guys, Chris from New Zealand here....finally bought myself a 914! Shes a '73 2.0 with original FI. Had her about a week, after standing for 8 years.

Previous owner spent some time and money getting her on the road as part of the sale to me, but still a bit of work to be done! I'll try and attach a picture.

Took her for a shakedown run today for about 3 hours but then she started coughing and spluttering then stalled at about 60mph. Coasted to a halt, ignition on/off and away she went again for about half an hour.. Same thing again, ignition on/off and all was well for another 20 min.. This went on and on and the intervals between spluttering and stalling got more frequent until i just about made it home.

Felt like fuel rather than electrical... Could it be the fuel pump, or any other ideas?

I have a feeling I'll be using the forum quite a bit (IMG:style_emoticons/default/smile.gif)

Nice to meet everyone!

As beatnavy mentioned check the grounds, connections, relays etc as it could be electrical,if it all looks ok check plugs ,leads ,cap,points and plugs ,could be something simple like a dying coil or points out of adjustment/or just worn out.
Reset / check valve clearances then start it up and check timing if you have a stable idle otherwise you need to make sure your aux air valve is working,you can test this by diconnecting the power wire and if it still runs the same the valve is stuck and not opening.
See how you go ,you can email me for a chat anytime ,like to keep up with NZ owners and chat ,cheers.
Oh and forgot to mention ,real nice looking car (IMG:style_emoticons/default/beerchug.gif) .

Thanks Porschetub! where are you based?

This was Alistair Moffats car in Auckland. He's done a fair bit of work to get ot on the road, mostly what needed to be done to pass a WoF and get it drivable, so brakes, clutch, gear shift springs, bushes, some FI hoses etc etc... It drives really well. feels tight and responsive, just the stalling issue to report after a drive from Auck to Mt Maunganui and back in the same day... The usual rattles and squeeks prevail, but nothing that some online shopping at Auto Altanta cant fix! (where do you go for your parts?).

Started ok this morning.. bit of a flutter, but a boot full got it idling.. Seems to idle high at around 1200/1400 rpm.

I'am based in Nelson bays in a 'one horse' town over the bay called Motueka ,moved here a couple of yrs ago .
I have bought parts from mainly from the west coast of the US as it keeps the crazy shipping cost a bit less crazy ,I can email you my favourites if you like .
Sellers on here are great also as there prices are generally very keen and NEVER had an issue with quality .
Sounds like your cold idle is in the ballpark so your AAR must be working ,could be an air leak to fix or an adjustment of the air screw,best to check your timing before doing this as it could be over- advanced or the distributor is a bit gummed up which is very common with 205 number units..
Sounds like a bit already been done so thats a step ahead in terms of labour ,time and $$$.
Included a pic of my NZ new car ,cheers.
