I6 Stalling problem
Hello, I have an 88 f150 I6 4.9L manual and I've recently experience a strange problem.
While driving the tach dances down and up and the engine severly hesitates and then eventually stalls out. This usually happens after driving in wet weather conditions.
Basically my truck has been running fine since January. When this problem last occurred I did nothing and it seemed to fix itself. I drove for 4 months through the winter with no symptoms. The problem has now resurfaced.
I've posted some videos of my Tach just to illustrate the activity at idle while in neutral.

If anyone has any suggestions please let me know. Below is my post when the problem last occurred in January.
-thanks
Andrew.

Hello,
I have an 88 f-150 I6 4.9L (manual) with a stalling problem. Initially the Truck would stall while running, and in bad weather. Since then I have put on new plug wires, a new rotor cap and master plug as well as an ignition module. The EGR in my truck was replaced in 1998.
Now my problem is a lot more mild, When I first start it up it will idle @ 1500rpm.. drop to 500rpm after a few seconds and run really rough and stall. After a few restarts it will finally run with the check engine light on.
I extracted the codes and they are:
Key on engine off codes
24 67
Computer Memory Codes
14 41 51

Check the ignition coil. That may be causing the sputtering and stalling of its getting any moisture in the coil. Try checking the wires by turning the truck on and spraying water on the coil wires. If its starts to sputter like that the coil is faulty. Otherwise check the dist cap and replace all spark plugs, wires, cap, and rotor inside cap.
