1975 1.8L Ljet injection. Car is hard to start. It takes 3-4 tries and some time a shot of starting fluid. Fuel pressure gauge reads 30 lbs. in engine compartment. The rpm rises to 1800 rpm for about 15 seconds, then the idle hunts between 500 rpm and almost stalling out. After the engine warms up it runs and starts as normal. Vacuum hoses are tight. Comments?

I don't usually comment on running faults with FI on the 914 because I have never worked on one with it.
I do know that nearly every older car I have bought with FI has had some sort of air leak from major to minor,I always do an electrical tune up first,then start looking for air leaks,it makes no difference if its L jet,D jet,CIS or Motronic they all run poorly with leaks ....to often certain component are blamed before the basics are sorted. I remember it used to be very common for mechanics to say..."oh well it must be your computer then" because they didn't know s#it about FI. |
