Help please! My 74 1.8 Djet dies at an idle, it runs okay at higher rpms but the tach just goes to nothing and it dies at idle.
The problems is it is intermitten (sp?) Sometimes it does, sometimes not.
It will start up right away and there is some gas smell.
Ayone familiar with this problem? thanks.
I am planning a longer trip but not with this problem!
Where ya been, Mike?
I don't know djet, but if you want someone to go through hoses and physical stuff we could meet later Sunday afternoon. Maybe I can get Dave too...
call or write back~

Are you sure it's D-Jet?
1.7s and 2.0s had D-Jetronic on them.
1.8s had L-Jetronic.
The two are very different. Please post up a pic of your engine bay so we can tell which you have.
Start by replacing all of your vacuum lines. That's usually the #1 reason why L-Jet (and D-Jet) has failures. All of those rubber hoses in there, except fuel lines, should be replaced. Check back with us after you have done that
If it still has stalling issues after that, it could be a timing problem, bad points & condensor, stuck open/closed injector, bad vacuum pot on the distributor... The list goes on and on. First and foremost start with the most common problem, as mentioned.
Looks like someone was smart enough to replace those intake manifold seals with rubber instead of the cloth-covered hose that is normally on there.
When you've got no vacuum leaks, the engine properly timed, good points and good ignition, L-Jet runs fabulous.
Mine does the same thing. I just replaced the vac lines and now I've discovered a fuel leak underneath (had the gas smell too). I haven't tracked it yet, but it's under the block, not the pump.
FYI, before I replaced the lines, it would not run for more than a couple secs.
Good luck, I'll let you know what I find.
A proper tuneup, beginning with a valve adjustment is the first step. Inspect the TWO seals on the oil filler, as well as the condition of the gasket at it's base. Replace as necessary. All the vacuum lines and hoses need to be in excellent condition. The vacuum advance/retard can needs to be intact and functional. Vacuum leaks KILL L-jet systems.
BTW, FLAPS hose really doesn't fit, so don't even bother. The Cap'n
"it could be a timing problem," I had this done this spring
bad points & condensor, (Also done this spring)
stuck open/closed injector, ( How can I check this?)
bad vacuum pot on the distributor ( How can I check this?)
I am replacing one vacuum line, the rest were done last year, but one old one remains.
Next? Thanks.
other sources of vac leaks. injector seals (easy to renew) and the phenolic spacers/gaskets at the intake runner to head. the runner to plenum hoses are pretty crappy too. you shouldn't need the clamps. i can't figure out what the hell the story is with the engine compartment fan hoses. for now, get them out of the way and cap the j-tubes so you have room to work.

Hello,
I drove it today after fixing the vacuum line and so far it seems to be fine, I got it warm and it did not die, thanks to all of your help.
Mike
