well about a week ago i had my battery disconnected to replace a cable terminal and since then it has idled rough (always does for 200 miles or so after the computer looses power) but its been long enough it shouldnt be idling that rough anymore. it has also started to run really rich and lacking power since then. fuel mileage dropped from about 17 to about 14. checked codes and got 18 and 33 from memory, 12, 33, 13, 73 while running which are as follows:
12 cannot control rpm during self test high rpm
13 same as above, low rpm
18 erratic idm input to processor/spout circuit grounded
33 egr not opening
73 dynamic response test failed
egr has never worked and i've never had problems with it, and the goose test failed was my fault so its gotta be ignition related, i checked my tfi module with an ohm meter and it passed, so i cleaned it and regreased it, checked my timing and it was fine, checked for spark on all 6 cylinders, checked fine. checked for obvious frayed or chaffed wires and even replaced the computer with no luck. anybody have any suggestions? seems like its gotta be something to do with the code 18. tomorrow i will check codes from the othre computer and will likely replace the upper intake and all sensors unless anybody has suggestions (i've already got the parts)
