How much will it be to repair/replace the pcm on my truck? and also, how long?

yes. I Got a diagnosis from Good year several weeks ago, and they told me they don't do such repairs. They replaced my spark plugs( they thought that was the problem), but turned out not all of them were firing, therefore they concluded it was the PCM. so I took it down to another repair shop(its still there) going, on the 2nd week now, because they said they had to order the PCM thru the dealer only. Anyways, the part came in to the dealer last friday(so I was told), but was not delivered to the shop yet. Yesterday when I spoke to the repair guy, he told me that if its not delivered to them today, he will go down to the dealer to pick it up. I am being charged $1225. Is that about right?

1225 sounds very high. why did they not go get it friday?? it all sounds fishy. the price is high even for a dealer. Roy
