Message	Can you open up the ECU Case, and have a look and see if your ECU is Socketted?.. The Symptons are of Limp Mode.. Corrupted ROM, and the Main ECU can not read the Program.. The ECU Electronics will go to a mode where it at least able to make the engine run SOMEWHAT, so you can get it off the road.. It's an ECU thing.. You could also have water damage that will cause the ROM to be not readable sometimes.. Or just grab another ECU ( Ebay? ) and try that.. Cj
