Hello all,
Still having a problem with my wife's 93’ 240 missing and stalling out under acceleration that only happens once per day in the morning.
It will idle fine but as soon as she take off it will start to stumble/miss and sometimes stall out. This happens about three (3) miles from home as she’s waiting to get on the freeway.
Once on the freeway at higher RPM’s it then runs fine for the rest of the day.

Problem was intermittent but now happened every morning and runs fine for the rest of the day.

Starts and drives fine when cold for the first three miles only.
Then it starts to act up until fully warmed up then runs fine.

*So it runs fine when first started cold and when fully warmed up.
*Only acts up in what I’ll call the “luke-warm” time when it is no longer cold but not yet fully warmed up.

Based on my past experience it seem to be starving for fuel when it acts up.

Checked all the usual stuff and replaced the fuel pump relay.

I figure the fact that is only happens when “luke-warm” should help to diagnose the problem.

I really need to get a handle on this problem as this is my wife’s daily driver.

Has anyone ever run across such an odd situation as this or have any suggestions.

All suggestions are greatly appreciated.

Thanks,
Dale
