Twice now within probably 1,000 miles or so, Ive had trouble starting my truck. It sounds like it wants to start, but stutters and fails. I'll try a few times and it's the same each time. Yesterday, I had the issue and I pressed down on the accelerator while she was stuttering and she fired up. Ran rough for only a moment or two and then was fine. No smoke or anything.Truck runs perfectly otherwise. It's got 209k miles. Like I said though..... It runs perfectly except for that occasional starting drama. Truck was recently shut down before each event so it was warmed up before it happened each time. Ideas? Thanks everybody.

 

Sticking IPR, or a faulty ICP maybe? Scan it for codes.

 

Check the oil

 

So does it start better when cold? If so, +1 check oil level. Also, how old is the oil?

 

Oil level looks good. It's been 8 months since the last oil change so it's due. Only about 2,200 miles since the last oil change. Truck doesn't get a lot of miles put on it. It happened both times when the truck was warm/hot. Never happened when it was cold.

 

Sounds like it's the IPR.

 

Could be IPR orings
