Let me know what you think
Let me get the details out of the way. 96 Miata all original with 158000 miles. Put on dino and exhaust params are spot on runs like a top with no error codes. Ok here where it gets interesting. For the last 10 months its been to 4 mechanics not including myself to see if we can figure out why O2,EGR,Cat sensors will not ready. All have been replaced and test good with good voltage and suction. ECM was swapped just to make sure that rabbit hole was checked. Boost EGR replaced and vacuumes tested. Tested draw amps and voltages with phantom draw of 27mamps. Started/alternator/battery all good. Radio removed and all fuses checked of course. Only notable issue is cruise control not functioning. Wiring diagrams show this as a possible issue with backup memory with ECM but not sure at this point. Haven't pinpointed issue with cruise control yet but am asking out there is this something anyone has run across?
