I paid $150 for the misdiagnosed EZL, then spent about 1.5 weeks looking for an EZL which, at my hourly rate, is expensive. Paid another $75 for the correct diagnosis and another $275 for a mass air flow meter installed which fixed the check engine light code. Car runs great. While in the shop, I also replaced two shifter bushings at a cost of about $75 including labor. The whole ordeal was more agonizing than expensive.
