hi guys, i have a question about my 89 ST, wont start, check my error codes from the check engine light, and i get a 12, 22, and 42, dist. , coolant temp sensor, and VSS (vehicle speed sensor). anyway, i replaced the coolant temp sensor and i still get the same code, my question is, how can you tell if your ecu is bad? or if one problem is making more problems for me? any adivce is helpful. if you need more details, ill tell you whatever you know
