Have a misfire in cylinder 1 on 99 Honda Accord lx. I change the timing belt. One I change the belt I turn the car on and it turn on normal?

A couple minutes later I noticed the misfire can’t tell from looking engine. I noticed it for the exhaust. No smoke was coming out. Took it apart to look at the timing and everything lines up. I saw the spark plugs and wires on cylinders 1 and 2 still no difference. Any ideas.

    Hmm, sounds like you could be off one tooth on the timing belt/camshaft gear??? If the car runs great, then I'd not worry about it. The engine has the ability to adjust the timing and will do so if the numerous sensors tell the brain box to adjust the timing. Might make sure you didn't knock anything loose while banging around in there.

    Do a compression check. All the timing belts in the world will not repair a miss, nor will new ignition components or injectors if the cylinder has low compression.

    My misfires on my Honda Civic were caused by a bad engine coolant temperature sensor. It took 4 months for the check engine light to come on so i kept throwing money at unneeded parts. Put in a starter, spark plugs, fuel pump relay and it was just a ect sensor

    Adjust the valves. Every Honda motor has a common problem with tight valves and they need adjusting every 60,000 miles. Have a mechanic check the timing belt marks. if you put it on wrong it will look right when you check it because you're doing the same thing wrong.

    N O, you DID NOT notice the misfire from the exhaust, as there are NO symptoms of a misfire that ANYONE can accurately diagnose in that manner.

    That said, the timing belt has absolutely NOTHING to do with a misfire. If you THINK the timing belt could be an issue, YOU need to have someone else service the car.

    Note: If this question sounds rational to you, it is EXTREMELY unlikely you would even recognize the timing if someone showed it to you,

    Changing a timing belt will not sort out a one cylinder misfire. It is obviously due to something else.

    You still have misfire. Misfire is not because timing belt, because new timing belt not fix problem, so misfire definitely something else.

    Ideas is take vehicle to certified mechanic, have them look at problem. You know much about Honda motor, but mechanic know much more. No shame if someone else know more about stuff than you, but big shame if fix it yourself and engine puke while driving to work. Even bigger shame if engine puke while driving with girlfriend.

    Mechanic is good idea.

    Maybe check the distributor and your boots and wires. Could be valve cover gasket pushing oil into the spark plug wells.
