I have a 1999 civic ex which just started to shake everytime I would accelerate yesterday and today the check engine light turned on and it even started to blink at one point but it stopped blinking. Now before this I had take the car to get tested for emissions test and it failed due to the catalytic converter so I looked online and i found out that scotty kilmer had luck putting one gallon of lacquer thinner in the fuel tank. So i tried that and about two days of driving this started to happen. Is there any suggestions of what could have gone wrong?

 

Could it be something as simple as a fuel filter?

 

Why would you do that?? I would drain the tank,put fresh gas, prime the old fuel/lacquer lol out of the fuel filter(with it disconnected into a bucket) for 10 minutes. Then put on a new fuel filter,change the spark plugs, run seafoam through it. After I would get a new cat welded on which should've been done the first time to avoid all this.

 

Pull all CEL codes and post them.

How old are the spark plugs, spark plug wires, cap, and rotor?

Have you removed the distributor cap and inspected the internals?

 

The distributor is new, im not sure how old the spark plug or spark plug wires are but they look good still im not very good with cars sorry

 

Start by replacing both^ and then go from there.

 

Will do, any recommended brand? thank you

 

Honda spark plug wires and the NGK plugs recommended in the Owner's manual for the D16Y8 engine.

 

Thank you ron
