i was driving and my truck reved up to 2000 rpms it will go higher but not lower i have codes but the only one sorta relavent is p0230 but that doesnt makes sense with the probly any ideas?

 

need more info....year of truck for starters

 

it is a 99 with 200,000 miles i have a edge compbox but it has ben unpluged and the issue continues i have a holly blue pump feeding my vp44 with plenty of fuel

 

P0230 Fuel Pump Primary Circuit Malfunction
might want to check wiring to the lift pump

 

I'm sorry but I can't resist! You're at the wrong forum, I beleive the one you are looking for would be www.toyotaforum.com

 

the code is probably due to holley being there and i would guess the original pump is no longer hooked up, so thats probably not much of an issue, could possibly be the apps sensor, might try to reset it, but probably have to replace it
