Subject: RE:93 LT1 wont go above 2000 RPM by LT1Marc on 2007/6/30 20:59:53 hello Andy, after getting out a meeter, we discovered the following...I had a bad ECM that I got off ebay from a forum member...hopefully I can send it in for a rebuild...so after putting back the old ecm...which in the end wasnt the problem..the following weird things would happen.... while having power applied...after sitting for several minutes..the headlights would shudder..and the AC would come on..without any commanded inputs. Upon further tracing with the wiring diagram, it was discovered that we would get a code 42 and that the throttle body was NOT receiving any power even with the engine started, as well as the air codidtion low pressure sensor giving an indication. we traced this to the wiring harness being probably pinched when the automatic transmission was installed..so the tranny probably needs to be pulled and the wire harness inspected. I am returning to Iraq today...we were supposed to be home now but the powers that be decided that a tour of duty is no longer one year..but 15 months..Ill get back to her in November...in the meantime..any idea how I can get that wire harness..or do I just trace the wire and try to fix it? |
