'73 99 idles, dies when gas pedal is pushed

This is another edition of "Why lawyers should not do car repair"

I had great plans for the green '73 99LE today, but I had to get it from my office parking lot to my garage at home. About 2-3 miles on side streets.

But it regressed, mobility-wise. The car would start, run for 5-10 seconds, then die. This slightly improved over time, to maybe 20 seconds before it would die. Disappointing because yesterday morning it ran and I moved it all around the parking lot.

So I gave up. Came back a couple of hours later. Car started and idled and did not die! But the instant you hit the gas pedal, it dies.

Thoughts? I know this is probably absurdly simple.

Greg, I will buy the car for $700.

That will solve this problem.

Nothing, which is why I never bought it in the first place

On a slightly "on topic" note. Have you replaced the normal mantainence items on the car yet? (plugs, plug wires, dizzy cap, dizzy rotor, clean the battery tra grounds per the advice on that other thread)

If not, get on that!!! I remember the plug wires feeling like stiff plastic when I had a look at the car, clearly that stuff is worn out pretty good.

Once that is all taken care of you might be able to rule out the simple stuff and move onto more complicated potential problems such as faulty D-Jet components and so on.

the gap / dwell on the primary points may need to be checked, also may need new points. Also be sure to check the gap on the secondary points (in the second level of the distributor). These are where the D-Jet system gets it's "RPM signal" from. Also, grounds. Battery tray grounds on these cars are very common to have fail. Also check all other grounds. Don't just physically look, do a resistance check.

well, that I would check first anyway. There is the possibility that the D-Jet system is working perfectly. get a manual for the Bosch D-Jetronic system and read this --

thanks for the detailed advice

I haven't really done anything yet, I was going to drive it home and start the process. I have bought a cap and rotor, wires, and plugs for it, and a new fuel filter (although the seller claimed the filter in there was recent).

It feels like a fuel issue to me.

Well, yet another lesson in not taking anything the seller says is true, i.e., claims of a relatively new fuel filter.

Replaced the fuel filter. Rusty debris is falling out of the old fuel filter as I pull it off the lines. It also weighs about 10x more than it should weigh. EDIT - the old filter was also installed backwards, the "OUT" side was attached to the fuel pump line.

Install new fuel filter. Jump start car. Hit gas, notice engine revs up and does not stall. Problem solved.

It's running rough - there's more work to do. But it gets gas now.

Well, there you go.

Good thing it came off easily, unlike on Big Red.

Much easier. It's a smaller filter, and you access it though a panel in the trunk floor. No mounting hardware either, just hose clamps on either side.

So no diving under the car and swearing when when the bolt won't move separately from the filter itself.
