My 06 mega cab is starting to vibrate a bit on a cold start. It runs ok, but when idling, it seems to have a slight miss. When I get back, I will send an oil sample to Fluidlife, to see if I have any fuel in the oil. It turned over 200K, on my last rip to Fort Mac, a few weeks ago. My fuel economy, is still OK. I think the injectors need to be evaluated. Can anyone recommend a good shop, around the Edmonton area?
I want to thank the guys who recommended the winter fronts. Bought one from my cousin (service advisor) in Calgary ($159.00) and the other in Leduc ($217.00-???-***)
