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! |

My $.02 (US). It's not vapor lock. If it was, in my experience, it wouldn't restart immediately. You'd have to wait til it cooled down to get started again. I think the comments about rust in the tank and clogging the sock fit the symptoms perfectly. The tank isn't hard to pull if there's not much gas in there. Don't think of it as a last resort. Can't help with the idle and rough running, that's for the experts. Good luck and....

(IMG:style_emoticons/default/welcome.png) (IMG:style_emoticons/default/agree.gif) fits the bill. good place to start. my 14 is an L jet so can't help with D jet. if its not bad fuel, dirty tank then mr. @emerygt350 is probably on track with what he is speaking of? a quarter of a century ago i did pick up a bad tank of fuel. water in the petrol. car almost refused to run. when it did, misfires, spluttering, backfires. etc. had to flush the tank and system. injectors esp do not like gunk if it manages to get past the filters. even the smallest particles or impurities. to note it did not come good during that episode as your car is appearing to after you switch off. tends to make me think the fliter or filters if more have been fitted are blocking up then after switch off doing the classic temporary clear as the much floats back off the filter surface (for a little while). you would only get vapor lock if the pump is in its stock location under the engine attached to the right hand chassis member behind the cabin. and it only happens after a hot shut down and not while you are on the move. it won't be that. good luck with it. ------ and hello from across the tasman. looks like you picked up a sweet little 14. lots of interesting cars in NZ, most kiwis i have run into are petrol heads of the highest order and practical people.
