please help im new..engine has rough idle

[bonacci10]

well my truck was running perfect (just bought it) then i noticed a oil leak from the back of motor, come to find out it was leaking out of the icp sensor...the o ring was bad on the sensor and the thing was barley hand tight!! so i go and get a new o ring and put it right back together.. no more leaks but now the truck idles loppy and even rougher when u put it in gear? any ideas i took it for a good ride and let it warm up if definitely lacks power for sure....

what should i do? take the sensor out and buy a new one>? it was running fine until i took it out to put a new o ring on there. hmmm..


thanks guy i reallt appreciate it

no codes... with a reader from advanced auto tho

Their scanner wont pull the codes correctly. It needs to be CAN capable. Start a thread over here asking if anyone can scan you in the area.

oh ya, 03 and 04's dont throw a ses light for nothing, ive had 2 egr valves go out egr cooler, oil cooler,(blew the head gaskets) sticking turbo, and one injector. all without a ses. good thing i had a scanner to get the codes.

could be the sensor but i would have it scanned and see what your icp pressure is. and/or what codes come up. it is weird thou.

well i found a can capable scanner (Amazon.com: Actron CP9180 AutoScanner Plus Diagnostic Code Scanner with Live, Record and Playback Data Capability and O2 Monitor Test for OBDII Vehicles: Automotive how do i get in deeper than just reading a ses light or will this unit do the job for me? its in my hands right now...

most scanners only read basic codes, your going to want to get your hands on a ae (auto ingenuity). did you hook that one up yet? if so what did it show.
