*Closed* 20% Off Supercharger Group Buy 2nd Gen 4.0 Engine

The only thing that makes me think it's the trans is when I put the pedal to the floor it's shifts through first and second but when it goes to shift into third it just bogs down.

 

Would bad gas cause that?

 

Eh bad gas I wouldn't think so. Just be sure you have the right octane but you would be pinging.

interesting. That I would have no idea, hopefully someone can chime in soon. I'd imagine not a practical time to be experiencing issues on a road trip.

 

Did you upgrade your fuel pump or are you using the stock fuel pump?

 

at least you are being honest. ;-)

 

I upgraded the fuel pump.

 

Yea I had to get a hotel room for the night and I guess my only option is to take it to a dealership nearby in the morning. I have no freaking clue what is going on. This supercharger has caused nothing but problems since I put it on. Getting some crazy ass driveline vibrations too but that's a whole different story. Possibly because of the trailer I'm hauling.

 

Good question

 

What about a bad fuel injector?

 

Coulda overnighted the hoseclamp on fuel line, which cuts the line causing hard start.... actually quite common.

Then again, im not sure about the 3rd gear issue

 

Well there goes that idea.. I don't know man, if I had to guess I think it's something fuel related, but I am not an expert. Hopefully you get it fixed before it causes any damage..

 

Maybe 3rd gear stumble cause the fuel demand cannot be met?

It's just weird because the truck has been doing fine for a thousand miles. Then all of a sudden out of nowhere it started acting up. I think I have a small pressure leak from the lid of the fuel tank which is causing the hard start. I'm just more worried that my AFR is all jacked up. Would a bad MAF sensor cause this?

 

Ive seen maf sensor issues personally act rpm dependent and not gear dependent, BUUUTTT, its an easy task to clean ur maf sensor, and k&n have been known to be overoiled easily.
Id try it 1st.

I mean, that may be it? I just would notice it in any gear at a certain rpm on my vehicle at the time

 

I'm also not hearing any pinging.

 

Wouldn't that throw a code? Are you getting any codes?

 

I wish someone with experience could drive it to see how it's acting. It's very strange.

What about this.... I drove through a rain storm. I have a leak somewhere on my gas tank. What if water somehow got into my gas

 

Bro my dash looks like a Christmas tree right now.

 

TRAC on light, check engine light, and maint light are all on

 

U need to get those codes read and come back
