tonight i left the house and got less than 1 mile away and it died i cranked and cranked and no start it seemed liked the cps failed and so i took my spare out of the glove box and changed it still no start i ran the codes before changing the cps and got 5 codes p1211, p1212, p0340, p0470, p1670 and im not sure what they all mean i have looked them up and one is the cps but unless i have a brand new one that is bad then i think i ruled that out if anyone could help me it would be great and just a side note for the last month or so the truck has been idling rough and running somewhat rough until it really gets warmed up or runs great if u stay on the accelerator

 

That 1670 is EF signal undetected... I'd be suspicious of the IDM...

 

How do I test the idm
