Hello,
I have a '73 1.7 car with fuel injection. Just starting to get it back on the road after sitting for many years. The car starts easily, idles well, and seems to run ok when warming up. Once warmed up and on the road, intermittently the car will stumble like shut off and then just as quickly it will go again. Going around corners, not all corners, it will do the same but for longer periods of time. Pushing on the gas when this occurs, nothing happens. The engine doesn't rev. its like its disconnected. I recently changed the fuel lines at the fuel pump due to age and cleaned out the fuel injectors. Car has about 5 gal of gas in it. Any ideas on where or what to look at first? Does this sound like a FI related problem? Thanks for the advice. EJP914 |

Could also be a blocked breather for the fuel system. You use the car for a bit and as you do so a vacuum develops in the tank as you pull fuel out but no air goes in. Over time the pump can no longer overcome the vacuum and the car runs poorly. Leave it for a bit and air gets back in somehow and it all works again. One way to check for this issue is to wait until the car runs badly and then remove the fuel filler cap - if you hear the sound of air rushing in that's your likely problem.
