After about 5 minutes, the check engine light came on. It runs fine once I'm up to speed, but at idle still sounds like its dying. I took it to AutoZone to pull some codes and got the ones mentioned above. The P0125 I'm familiar with...I got the same code about 3 months ago. I changed the temp sensor and the check engine light went off at the time. Could the sensor be bad already? Or did I screw up the job? (most likely) The P1316 is completely new to me. It says "Injector Circuit/IDM Codes Detected." This is a bit above my pay-grade. Can anyone point me in the right direction? What do I need to clean/repair/replace? Thank you in advance!

Also, the P1316...I need to change the plugs and likely the wires anyhow...could this be causing the problem? Maybe some carb-cleaner in the right spot? Thanks again, Mike   Danno (Danno) Member Username: Danno Post Number: 219 Registered: 08-2002 Posted on Monday, April 21, 2003 - 10:11 am:    when i was recharging my AC, the purge control valve (on/near the charcoal canister) started to chatter away, had erratic idle, check engine light came on and then it stalled. a few more restarts, and no more chatter. a few more restarts and the check engine light cleared. i didn't happen to get the codes, since this happens every once and a while.   Mike Hughes (Mhughes) New Member Username: Mhughes Post Number: 8 Registered: 02-2003 Posted on Monday, April 21, 2003 - 11:22 am:    Thanks Danno...It runs rougher at times than at others...Hopefully this will prove to be self-correcting!! I do notice an oder when I shut her down...sorta like something is burning off. Carbon I assume?!?   Christopher Boese (Christopher) New Member Username: Christopher Post Number: 28 Registered: 10-2002 Posted on Monday, April 21, 2003 - 11:52 am:    Bad fuel? My truck stinks when I use Shell, but doesn't on Chevron. And idle smoothness seems to vary depending on what brand of gas I'm using.
