3.3 engine problem, quick question

[suhbliem]

I know you have all experienced this before, I have not so I could use your help.

It was about 35f today. Truck was running great for about an hour then all of a sudden the truck bogged way down like it was running super rich or something. It was odd b/c it happened all of a sudden.

I think it is a fouled glow plug but would a bad glow plug give such sudden and dramatic changes?

Another thing I had noticed was that the hose connecting the header to the exhaust had a large tear in it, could this also be effecting things? Only reason I ask is b/c the car was running fine with the hole in the hose before which makes me think that it is probably something else.

Any time you see a bad fuel or exhuast pressure line, you should fix it right away. It will affect your tune. The bogging was most likely a 'lean bog'. Your glow plug could be shot now too. It's always good to have extra line and plugs......it's cheap stuff compared to a new motor.

thanks a bunch for the speedy reply...

so does the maxx eat the revo's exhaust fumes then vomit them back into the revo gas tank?

Whaaa? If you are asking if the exhaust fumes go in to the tank then Yes. That is what gives you your fuel pressure. I think 2Revo may have hit it....you had a lean condition which ended up eating a glow plug. Sound like a good scenario to me. Fix the line and put you in a new glow plug and let us know how is goes!
