okay... my car started this misfire cylinders after i used the seafoam in my motor... i drove it for 2 days straight forgot to changing my oil. i search on this and most people say it might just need to clean the carbouator... (however you spell it) so i pour a bottle of carbouator cleaner into my gas tank. and now it just misfire in cylinder 1 & 3. what do you guyz think i need to do about cylinder 1 & 3? and no O2 sensor code is popping up just the misfire cylinders code. already change cap and rotor for distributor. any help would be good. thanks,.

Your fuel injected car does not have a carburetor. Where did you put the seafoam? I suggest a compression test.

 

i pour the seafoam in the intake, the oil, and gas. all 1/3. car was running fine until 2 days after the seafoam. and can my cat. convertor caused this? or O2 sensors?

 

the EFI written in your manual, fuel injectors, fuel rails, and the absence of a carberator should have given away the fact that you dnt have one

Perhaps some debris broke free in the fuel system, managed to pass the fuel filter, and clogged injectors 1 and 3. Try the compression test. It is cheap and easy. Also, have you looked at you spark plugs? Are 1 and 3 different?

 

fouled sparkplugs maybe?

 

will i check the plug and clean them. all of them were white except the 4th. the 4th was brown. the 3rd one had a little oil on it. all the plug wires are in the right places. the distributor rotor was burn at the tip and i replace it. still misfiring cylinder 1 & 3. before those check up all 4 cylinder was misfiring.

update: just when i change the plugs and reset the ecu. the ECL is off but when the motor is reving to 3k it back fires a lot. can the wires or plugs still be a issue? and i dont know if this causes my motor to misfire but a week ago my heat shield for my cat convertor broke off on the bottom.

I'd say it is a compression issue. Perform a compression check. If it is bad, adjust your valves and redo the compression test.

 

we'll do dogginator... get back to you tomorrow...
