intermitten problem at idle
this has been going on for a couple of weeks, sometimes at idle i am at about 900 rpms, other times it's normal 6oo or so, have had codes pulled , even when the engine light comes on it's not storing any!
Now even when the idle issue is going on it runs fine as i get into the accelerator , but i let off and it like lopes ?
not sure what to even look for at this point, anyone else has such issues , help please got a long trip coming would like to get it fixed!

IPR tinnerman nut tight?
Can you watch engine parameters with Torque or similar program and check for linear TPS voltages from idle to WOT?
How does ICP and IPR duty cycle look?
How does fuel pressure look under load?
Some ideas to check.
