1999 GMC Truck V12 Two Wheel Drive Automatic 138000 miles
This new body style half ton truck is used as my work truck. Over the past few years I have been having quite a bit of trouble with sensors. It is getting worse here lately. About a year ago I replaced a sensor (that my code reader said was defective) PO 141 and it went out again about 6 mos. After. Within the past 2 months I have had to replace it again along with a camshaft position sensor.I went ahead and replaced the entire catalytic system also. Then I got a reading that said the throttle positon sensor was bad too. Replaced that one. Now, within the past 2 weeks my truck kinda runs away at idle and my code reader says the following: PO 141 pd 4/04, PO141 02/04, PO 121 1/04. And Ive gotten misfires on PO 304 03/04?
