Hello
I have 1993 626 DX
Has been running great for the 2 years I've owned.
Just recently getting back to work from my winter vacation.
Car was sitting in garage most of the holiday season.

Anyway..
Now that I'm driving again, I'm having an issue.
It will stumble while accelerating usually around 2nd and 3rd gear.
Then right after that, the RPM's will drop drastically and go back up, then crash back down.. erratically..
Usually right after this happens the car will stall out completely.
After sitting for about a min with all power off, I can restart and go on my way.
Just until it happens again.
I have added fuel injector cleaner, and noticed i was low on oil and water, now filled.
Ran better for a day, but now back to the stalling.
Wondering if it is the fuel filter?
Will also stall out siting at a red light.
Last night stalled twice at the same light and wouldn't stay idling..
Then it did..

Thanks.. Any help will be greatly appreciated..
