ICP unplugged same power

I have been having power loss for awhile, no leaks or anything, but I tried unplugging my ICP sensor and it didnt change much power with the truck, maybe a little less power not really? Does it usually loose power unplugged? how much? trying to pinpoint a problem,

you might need a new icp sensor. check to see if there is any oil down in the connection. if so, then when you have it plugged in with the truck running and then you unplug it and there is no change in idle, then its no good. when you unplug it, it should make a rough idle and eventually shut the truck off. hope you find the problem. try this first

I had the truck shut off when I unplugged it and started it up. Ran about the same maybe a little less power. It didnt idle wierd or anything though, Did you have it plugged in running and then unplug it running? There isnt any oil in my connector.

yes i had it plugged running then i unplugged it while it was running. while the truck is running and its plugged in, then unplug it and if there is a difference, than its fine.

unpluging icp really doesnt tell anything and definitly dont buy one just because you think that might be the problem, are there any codes coming up in this truck , i would want to know that first, and is maintenance up to par

No codes are coming up in the truck. Truck has good maintenance. Just seems like it doesnt have the pull it should, Someone told me to drop the tank and bet its clogged solid . 165,000 gonna try that tonight, I have all new boots, y boots intercooler, turbo, HPOP, IPR, turbomaster wastegate, Should I be able to get it to puff a little black in stock mode if I put it to the floor out of the hole? I think the tank is plugged or weak fuel pump gonna start with the tank?

I think I have the same or similar issue with the ICP sensor on my father-in-laws 99 PDS. I have started the truck and then unplugged the ICP sensor and nothing changes, it will idle forever with no change in idle or throttled and there is oil in the ICP sensor's electrical connection. Thanks

PS I have checked and there are no codes but the ck engine light is on.

my check engine light isnt on, but something tells me the sensor is junk, has corrosion on it, no oil though, I think i will just buy a new one, see what happens, I might get a new map sensor also because truck seems to run better with my map unplugged
