Hello gentlemen. Yesterday my husband started to experience some issues with his truck. He noticed that when he started truck and took your foot off brake to engage into drive mode it turned off. He would turn it on and put one foot (left) on the brake and one foot (right) on gas pedal so as to avoid truck turning off. It worked. Battery light would lit up but he doesn't seem to think its the battery. Going 70 mph wasn't a problem. We were towing a trailer and truck didn't have problems. This is the first time we have had issues with his truck. Please help. I loooove this truck! Thanks.

Have you checked for vacuum leaks and the idle air control valve (IAC)? The IAC is responsible for maintaining the idle speed.

No we haven't. Can my husband do it himself or do we need an expert mechanic? And where is the IAC located? Thank you!

It is something you can do yourself. And, the IAC is on the throttle body. It is an electrical device, so wires will be going to it.

Hello gentleman. A close friend of ours who happens to be a mechanic for a Border Patrol station in our hometown helped my husband inspect his truck. He suspects it could be a term called "cold start"? Since it hardly ever gets below 40 degrees in our area he suspects that could've been the problem. Today it's nice and sunny, but just cool and not cool weather. Have you ever heard of such a term? I trust our friends mechanical knowledge but I also value a second opinion. Thank you and I hope to hear from you soon:)

I have to be honest, I never heard the term. However, he may be referring to a problem that I simply call something different. Regardless, it should start cold and run properly.

Can you ask your friend what is causing the issue? In other words, what does he feel causes a "cold start" problem? From that, I would be better able to answer your question

Let me know what he says. And, if I don't hear from you till later, have a great Thanksgiving!

Joe
