need help truck cuts out

[greatwhite57]

Need help my truck is cutting out sometimes and is not throwing any codes. I've done a whole trans fluid and filter replacement cleaned tb and reset the pcm and it still is doing it.

as in it has times it dont wanna start for a min??

 

[greatwhite57]

It starts fine and every thing it does it when I'm goin down the road or when I go to pull out some times. It acts like its missfireing but it won't throw a code.

 

[jbmobbs]

try your distributor cap,rotor button under dist cap,crank sensor ,spk plugs,plug wires, and coil mine did somethin like that and i replaced all that and it has done fine every since

 

[greatwhite57]

I'm gonna try plugs first then crank sensor. It only has 56000 miles on it its the 5.7hemi so I don't have a distributer on it I got individual coil packs

I agree with the plugs. How long has it been doing it? Maybe you got a bad tank of gas. Perhaps toss in some fuel system cleaner too. Can't hurt.

It's been doin it for about 2 or 3 days now. Im thinkin bad gas too cuz it does randomly. I pretty much ran all the gas out and put different gas in it this evening. I normally put a bottle of Lucas in it every other fill up. I might try seafoam in it this week and see how that stuff does

Seafoam is great stuff. Use it in both my vehicles.

Well I just pulled one of my plugs and it looks like **** so I'm gonna change them out tomorrow when its light outside

 

[jbmobbs]

[greatwhite57]

[greatwhite57]

Yea looks like it was time to replace em. You'll be happy with the Seafoam too.

 

[greatwhite57]

Should I put it in the gas tank or what's the best way to do it?

Here is a link to a thread I had a while back. The general consensus is 1/2 in the vac line and 1/2 into the gas tank. There are lots of videos on Youtube as well.
