I have a 1994 Toyota Pickup, regular cab, manual trans, 4x4 with the 22re engine. The truck and engine have about 193k on the odometer. When the truck starts cold, it runs fine until it warms up, or when driving. After it has warmed up, the engine will sputter and stall at idle - for example, when stopping at a stop light. The computer is storing Code 14. In the past 2 months, I have completed the following work/maintenance:

• New timing chain/water pump
• Valves adjusted
• New distributor/cap/rotor
• New plugs and wires
• New ignition coil

I don't have any vacuum leaks. Any ideas what else I should diagnose? Could it be the EFI relay or the Ignition Control Module?

Thanks!

Jim
