Occasionally when I stand on it or even ease it to the floor. It will act as if its flooding out or stumbling. I let up just a bit and it works fine. Would my airdog system help this out? Or do I have a bigger problem? Been doing it since I bought it. It does have a great to me sounding idle. Kind of a big cam gasser idle. ??

 

is it the Ex or truck?
sound like oil not air. maybe LPOP weak not feeding good.

 

Yeah sorry,in my truck. Doesn't the lpop keep oil in the resvior at start and idle,then at higher rpm the hpop keeps the psi?

 

the lpop feeds the hpop all them time.
at higher rpms the hpop will put out a lot of oil if the lpop is weak it cant keep up with the demands of the t-500.

 

It's not consistent though. Being a mechanical pump wouldn't it happen regularly? It does have 284k on it,probably wouldn't hurt to replace it. Would like to do the harmonic balancer at the same time too.

 

if it is inconsistent then it may be the ipr of the icp reading wrong. or maybe someone will come up with a better idea.

 

I need to learn an play with my AE more. Right now its all greek to me.

 

Bringing this back to the top. This is bothering me.

I'm thinking oil,because when I first start the truck it takes 1-1 1/2 seconds for the oil psi to come up. Reading off the idiot gauge on the inst cluster. Running the AE I have 1400+ psi driving at 65 mph and on a wot run it will reach just under 3500 psi. When I installed the T-500 I cleaned the IPR,everything looked good on it. I do have an exhaust leak on the #8 cylinder(manifold),but it's been doing it before this developed.

What are your thoughts? Leaning towards the lpop myself. Thanks guys
