OK, so my speedo problem is really being a pain in the ass now. Its still very erratic...works most of the time, but then out of nowhere, itll just stop and ill get a CEL. when i check the CEL, it doesnt bring up anything so I dont even know where to start. last night, the speedo stopped, CEL came on and then my lights stopped working...not running lights, the actual switch lights....then today after I reset the ECU, speedo stopped again, CEL came on and then the engine started acting weird. Around 2-3k in the rpm range, the engine was very rough, like it was trying to go but couldnt...any ideas on what the hell is going on with this?!Cry!
