Now that I have the break issues fixed it's on to my next project. In the mornings when it is cold out the truck idles rough. Roughly like I am pressing the gas and letting off until it gets warm then it runs fine. Could this be a dirty MAF and/or TB? My brother said his 99 did this same thing and cleaning the TB helped. I know it will be a good idea to clean them anyway since the truck has 184k on it. Just wanted your thoughts. Thanks.
