i just bought the truck a few months ago, and changed plugs wires and a few freeze plugs, my cel light has been on since i bought it and throws the egr code, last night i was drivin home and burned a little rubber on the way about a mile down the road it starts runnin a little rough and the cel light starts blinkin at me?!? im not sure what it is but it hasnt stopped and i dont know what it could be. please help

 

A blinking light means a chance to damage the cats. If an Autozone isn't very far away, they'll pull codes for free. See what code/s it has.

 

Good day,

There a number of reasons the CEL will blink... All point towards engine or Cat damage... I suspect your issue is a misfire or multiple misfires... This has happened to me on several occassions... Check this article out...

They state that even a loose or missing gas cap can cause your CEL to blink... All in all, get the codes read ASAP... Report back with all the codes so we can take the next step...

Good luck!!

Cheers!!

 

ok, just got back from the auto part store, i didnt get the code numbers but its a misfire in cylinder 8, egr code but i already knew that one and lean mixture or something like that in bang 2? i just did plugs and wires about 2000 miles ago so it shouldnt be those. Now what? im lost

 

bank 2*

 

Recheck the plug and wire on that cylinder.

 

i took the plug out of cylinder 8 and it looked new just a little dirty, so i wiped it with a clean rag and put it back in, fired it up and seems to be running fine, took it to get the codes cleared so we will see if any of them come back, still curious as to why it started misfiring

 

does the motor try to shut off

 

if the problem comes back pull the plug and test your compression you could have a bad head gasket
