Need help with flashing check engine light
So I haven't driven my truck since Saturday and this I go out to start it and it acts likr it has a miss or something. I have a heavy load of soggy land scaping timbers in the bed, and I head down the road and it seems like I have no power. Under hard acceleration the truck would not rev past 2500 rpms and the CEL would start flashing. I let off the gas and it quit. With gradual acceleration it was fine. It did this three times on the way to work. It sat for a about 10 minutes at work, then I had to drop my son off at scout day camp, and the truck ran fine. Should I be worried or do I need to do a tune up?

Flashing CEL: Problem that requires immediate attention
Solid CEL: Problem that requires attention soon
FYI, incase you didn't know.
I agree with HeyYou, sounds like a distributor issue to me, Leave your hood up for a few hours, give things a chance to dry out then try it again.

Actually, flashing CEL is traditionally a missfire, which as you stated, requires immediate attention. So, either a bad plug, plug wire, cap, rotor, coil, or plugged exhaust/catalytic converter, can cause all of those issues. Also, if the issue happens to be at all related to the fuel level of the truck, then you should suspect a fuel pump. As the fuel level drops, air enters the fuel system, causes missfires. I believe across all OBD systems, the flashing CEL is reserved for missfires, but I could be mistaken, in that some manufacturers may program the flashing CEL for other malfunctions.

Why not do the key ON/OFF 3 time thingy and check to see if you have any codes in the computer? If it is a misfire, it could point to the paticular cylinder that is misfiring. If it points to #8 cylinder, suspect the intake manifold plenum problem... Good luck.
