96 Honda passport engine light blinks and car shakes whats the problem?

Answer 1

The engine light is blinking because the engine is misfiring, ie the fuel is not detonating in the cylinder as it should... There are multiple causes for why this could be happening, too much or too little fuel, no spark, lack of significant compression or too much or too little air... These are the only components that you absolutely need to achieve proper combustion in an engine, this light blinking indicates that something is not taking place at the proper time or in the proper volume.

The light blinks because it is indicating that the condition taking place can cause significant damage to internal engine components, or your catalytic converter (dumping excess fuel into the converter will burn it up)

I would suggest immediately taking the car to a trusted repair shop.. Estimated cost for doing a basic tune up (starting point) is around $300, however, don't be surprised if the estimate is significantly more if other engine mechanical problems exist... Do a little research, and find someone who knows what they're talking about (who really knows, not just one of those guys who can BS really well). If you can't explain the idea to someone, the repair shop hasn't explained the problem clear enough to you, don't be afraid to ask questions.

Good luck
