I'm getting that misfire code and my husband's friend who works on cars at his house told me don't throw anymore money into that car,cuz it has a bad number one cylinder Although I'm not ready to throw the towel in just yet cuz when my car gets going it's strong and has alot of power still! He said he put a new spark plug in it but didn't resolve the problem ? Well first he told us it was the coils but then said it wasn't the coils ,said he worked on it for 3 hours and charged us a $100 bucks but said the cylinder is bad and cost lots to fix it! Not sure what I should do prob go have all new spark plugs in maybe?! What do you think ? Thanks,Vickie.? ? ? ? ? ? ? ? ?

Oh I have a 97 toyota camry with 167,778 on it but I've had alot fixed on it too,like knock sensors ,head gaskets, had the oil uptake tube put in cuz it was clogged man I've put like over a grand into it ! Not giving it up yet!

You should get a second opinion. The next step is to perform a compression test, It's possible you have a problem with the head gasket. Replacing the head gasket it's expensive, but less than replacing the engine or the car.
