obs odd issues

Ok so here is what I got going on... its a 95 F250, 5 speed with stage ones, a custom tuned chip, intake, exhaust, gauges and fpr shim.
When I start the truck cold or hot it lopes from 400-1000 rpms until i feed it some fuel for a min or it just stops after about 20 seconds. Also when bringing the motor down from anywhere above 1500 rpms it idles down very low and then slowly climbs back to normal. The idle seems to be getting weak where as used to i would need no fuel at take off and now i must feed it a bit to get her rolling. The idle is so weak that the a/c compressor puts a noticeable load on the motor, just driving the thing runs awesome but these issues have been bugging me. I have checked all the filters, the oil was changed last week and it only has 73k on the clock.....
any ideas fellas???? i was thinking icp or ipr but any input would be awesome.

Thanks in advance

Its an oil issue most definitely....

Check out your ICP sensor to begin with, next step is the IPR!

Im going to be hooking up to a scan tool fairly soon... what should i be looking for as far as a reading from the icp... and how would i check the ipr? when i unplug the icp it throws the code and still lopes at start up... so im leaning towards the ipr

yeah if you un plug ICP sensor it defaults to stock ICP settings, which should eliminate the problem if your ICP really was bad. So you have proven its not bad.

The IPR is a tricky one, easiest way to diagnoise is replace it with a spare one honestly! They are SUPER tricky and can go bad in a moments notice if a tiny partical gets plugged up in one!

did you ever check out the IPR? I bet anything its gummed up with something...

If you can get your ICP while its cranking that will help a lot, AE and scan gauges can do this

No I havent got a chance to check it yet... I'm thinking the hpop might be the prob because it only does it with the chip in... And in my mind I'm thinking that stock the computer is trying to feed stock injectors and with the chip it's trying to feed my stage ones... I may be wrong... What do you think? And how do I check and clean my ipr?
