So i followed the how to's on the site and added 1/2 a can of the Seafoam through the brake booster this morning. Let it sit for 15 min then started the truck and drove slowly around the neighborhood till most the smoke stopped ( 5-10 min) then drove to the store and back. 40 miles since I used the Seafoam the rough idle at startup has stopped, but now when i rev the engine, such as accelerating, up to around 3000 rpms then let is go back down to idle while i coast, it has a rougher idle than it use to at startup and i have the check engine light come on every two or three minutes, blink a few times, then go away. I checked and the brake booster line and i secured it back tightly with the clip. Any suggestions or do i need to keep driving around?

 

More than likely you either fouled a plug or one of the O2 sensors took a crap.

I would do this. After a day or two of regular driving, see if the problem has corrected itself. If it doesn't, then ^^^^ What he said ^^^^.

 

Might be a long shot but try disconecting the battery for 20 minutes

 

All of those are good suggestions. My Sammi still smokes a bit after running seafoam through, I think there's some carbon that's come out and is trapped somewhere burning off.

 

o2 sensor

 

You drove it gently??? I whooped the hell out of it to get those carbon deposits out!

 

Is that why your trucks have been having trouble?

 

lol...NO!

 

Taking engine advice from travis is like taking transmission advice from me

Well, we both should have avoided teh water...

 

=]

I'm just hard on vehicles! The new rig I was issued is beat to hell cosmetically and I have a turbo going out already =\

My dad calls my big rig 'the war wagon'

 

Ouch!

Don't you get in trouble for messing up the trucks? Or is it just a company thing?

I know some driving agencies have an "allowance" per year on repairs, if you go under it, you get a bonus (sometimes the difference) and such.

 

I try to hammer things back into shape. I just gotta find a big enough tree to pull my bumper back into place. I have a leased truck w/the top of the line maintenace package so it's Ryder's problem =] The bossman def prepared himself for a new driver haha.

 

Awesome!!

I wish my truck was a lease w/ top of the line maintenance package too...I could use a lot of repairs!

 

all right guys, im gona give it a day or two then look into the o2 sensors

 

How many miles do you have on the truck?

If the CEL light came on, it should have stored a code in the computer. Take it to a local auto zone and have them pull the code for you. That will tell you what the issue is.

 

I want to seafoam my truck..but I think ill find a way to mess it up lol

 

the truck almost has 100k miles on it

170 miles since the seafoam and still has the same problem, the check engine light didn't come on for the last 100 miles. I'm gona go to Autozone tommorrow and see what they can tell me, thanks for the suggestions guys!

 

okay, so autozone says it is not throwing any codes, and the truck has stalled out three times this morning alone, any other suggestions?

 

Had the same problem with my 4.0 last fall with seafoam,ended up to be 2 fouled plugs,and the check engine light was from a mis-fire,I replaced the plugs and disconnected the battery for 10 mins or so,problem went away...........

 

thanks, ill look at the plugs

 

Did you ever get this issue resolved?

 

Don't you have to change the oil soon after putting this stuff in your engine?? Also isn't flashing cel a misfire which would probably be fouled plugs?

 

if its through your vacuum lines it shouldnt get in your oil at all, if it does then you have worse issues

 

the problem is taken care of. I changed the plugs, (had 100k on them so they needed to be changed anyway.) And then changed the oil. Some say do it, some don't, it was time for an oil change so i played in safe and did the seafoam before i did the oil change.

And yes seafoam is AMAZING! I have done three other vehicles since i did mine, none of those had post-seafoam problems though.
