We recently changed the thermostat, put a tune-up, changed distributor cap, rotor, spark plugs and Ignition Control module. But, the truck still struggles going down the road. Also the service Engine light blinks. Could you give me somewhere to start?

A blinking check engine light means that there is a pending trouble code. You must scan your computer with a scan tool. Or you can take it to autozone or a place like that and they will do this for free. Get the trouble code and let us know what it is.A check engine light is a good thing when there is something wrong; because it will usually guide you in the right direction.
