Ok, I'd really appreciate some answers. I took my '04 Honda EX CIVIC to the dealership for a diagnostic. The tech says the screws came loose in the alternator, and that the alternator fried the ECU. Now I replaced the alternator. The engine starts, the battery light stays on, the engine light flickers on/ off, the speedometer drops to 0, and the car won't accelerate at all. Its my understanding the car wouldn't even start if the ECU were fried. The ECU is on order although I am skeptical it is in fact the ECU. What is the actual problem, or is it the ECU?
