[QUOTE="97cherokee, post: 1553824, member: 22488"] so about a week ago i noticed that my truck doesnt have the butter smooth idle its had since i did the hrx and frx... i start the truck cold and it idles butter smooth, leave work go about 2.5-3 miles come too the stoplight and after a few seconds itll idle funny... not skipping just idles funny and not as smooth. get on the highway for about 18 miles with no issues, get off at my exit idle is slightly off but not near as bad when the engine is warming up. i monitored my icp and ipr. cold icp commanded is 600 psi, measured 600 (with in about 50-75psi of commanded) ipr is 16.4-18.5 depending upon which tune its in. when it starts too idle funny icp is between 450ish and 720 while commanded is 600 and ipr is in the same 16.4-19 depending upon tune. 2 weeks before this issue started i installed a cnc fab hpop and a motorcraft ipr, irate regulated return kit. the other day i looked at my icp sensor and found it too be leaking oil. today i installed a new zibbits icp sensor. ( i read really really good reviews on it and it wasnt an ebay special sensor nor ebay price) cleaned the connector and ran the truck and it does the same thing... any input? injectors are ffd 180/30s about 2.5yrs old and have under 30k on them. thanks!!!
